called a Honda dealership and asked how much to remove a shim. they said $791. I laughed, watched your video and for $22 bucks and 3 hours with the wrong tools, did it myself. my bank account thanks you, man!
@tylerthegeek28 will Honda do an AC diagnostic for free, and find the actual problem? Without any agreement to fix it with them? I’ve been searching online for my issue, and can’t seem to find the exact same problem..plus my mechanic took that probe tool and checked my relays with nothing showing wrong.
Most likely not, pretty much once they pop the hood you'll be paying. It would probably be around $100 for them to do a diagnostic but there is no guarantee they will find anything within 30-60 minutes they have the car then they'll start charging you more for taking things apart or off the car etc. Honda wanted almost $800 in labor to replace my AC compressor it would have costed almost $1700 using "genuine" Honda parts. I bought parts from NAPA and had them installed for $400 cheaper then the dealer
Thank you so much for posting this video I had the same problem with my 07 and thanks to this video my A/C is running like new again. Took me about 10 hours but saved myself well over 1000 bucks in labor. I also changed out the serpentine belt too.
Update on snap rings. Completed this replacement on my 03 accord. Everything was the same except for the clutch plate design. I purchased a set of Craftsman 2" pliers 9-47412. Unbolt the compressor to reach the ring notch which was at 2 o'clock position. I was able to get the grounding bolt out and replaced with a std bolt 5mm x 8mm. AC's back in business. Thanks guys for a great video instruction
Hey guys, giving you heads up. I've finally fixed my 08' civic. AC is now blowing ice cold air. You're video saved me $900 in labor cost, that coil replacement was a pain to take out. Thanks for the video, really helped me, only if you guys lived close to the New Orleans Louisiana area, I would have treated you guys to lunch. Lol. Now I don't have to sweat my balls off this summer like I did last year. Thanks again, God bless.
Yay.. my car's A/C is fixed :-) Eric from South Main Auto walked me through my exact problem. My A/C would run for about 10 minutes and quit.. then blow warm air. I took my car to a local shop and they recharged the system ($40)... issue remained. Then they replaced the condenser (which looked like Swiss cheese $400)... issue remained... GRRRRrrrrr. So I turned to youtube and I fixed the A/C clutch ($0) and the issue is FIXED! Thanks for being my virtual mentor Eric :-)
Thank You! Excellent information and video; Very Helpful in guiding me in replacing the A/C clutch on my '06 Civic. I learned a lot from reader comments and wanted to contribute in an effort to assist others. - Straight forward repair (with the help of this video). However re-installing the inner larger snap ring which secures the electromagnetic coil to the compressor nearly did me in! Not too hard to remove it but Very Difficult to re-install. I found reusing the original Honda snap ring was helpful. It was easier to work with than the ring that came in my clutch kit. It has smaller holes for the tool to fit into, has a slightly larger gap, and wasn't as prone to twisting when fully expanded. The snap ring tool that worked for me (although not a quality tool) is the straight-external tool from this kit - TEKTON 3576 Internal / External Snap Ring Pliers Set, 4-Piece. To work for this repair the tool needs to have long needle-nose like ends, which give you some working room between the coil and compressor shaft. - Snap ring tools I tried that did NOT work for me in this tight space are: GearWrench 82033 Double X External Snap Ring Pliers and Channellock 927 8-Inch Retaining Ring Plier. - On the '06 Civic if you also change the serpentine belt please note Honda Service Bulletin 06-059. Your replacement belt will be longer than the original and needs to be routed differently. - In my case the A/C compressor had to be unbolted from the engine to allow enough space to remove the clutch (it hits the frame otherwise). There are 4 bolts holding the compressor to the motor; the two on the bottom are easy to spot and the two on the top can be found next to the inlet and outlet compressor hoses. All 4 bolts are long and come in from the front. - The philips head screw holding the coil grounding wire is an M4 and 8 - 10 mm in length. - I was surprised to learn that the cost of a replacement compressor with clutch was roughly $300 (US). I was so-stuck on the inner snap ring that I considered replacing the whole unit and paying for a system vacuum/recharge ($135 US). Hope this information is helpful!
Hey man, thanks for the model of your pliers. . I am stuck trying to get that inner snap ring off, my $13 pair of snap ring pliers from a local store can't get it. I'll try yours
Hello Randy I am having similar issue. I have an 06 civic and am not able to get to the bolt. So do I have to remove the whole compressor unit out or just remove the 4 bolts to give more space. Someone told me I will have to release all pressure and Freon before I remove anything from the compressor. My issue is i am having weird noise from the belt area and when i removed the serpentine belt the only pulley that made a grinding noise was from the a/c pulley. Could that be it or maybe I need to change the tensionor. any help will be awesome. About to order parts dont want to order something unnecessary. oh I am getting cold air no problem there..it's just the noise and it makes a higher pitch noise when the clutch stops spinning.

i found that the compressor bolts are a lot easier to get to if you pull the fan. Two bolts at the top, wire harness disconnect and the fan will lift out. It's a little tricky to snake out, so be careful not to damage the radiator while you pull the fan. Once the fan is out, it is much easier to get to the bolts.. from the top.
Hopefully your repair goes easier then mine did. The front snap ring was a*itch to get to, had to borrow a set of snap ring pliers from a friend. Finally got it out and then focused on getting the pulley off, it took alot of beating and banging and a few choice words, spent almost a full day on getting it off. Came real close to pulling the whole damn thing off so I could work on it. Hub pullers unless it is a very small/narrrow one won't fit in the confined space. The snap ring on the outer side has a very small diameter hole. The inner has a larger hole. I had to use two different pliers to access each one. Good luck if you choose to start this repair,
My clutch was apparently seized (or something, it wasn't turning on with the fan or AC when switched ON, didn't engage, I replaced the Relay switch but it still didn't engage). I poked it with a long stick (car & AC off) and it started to spin! Cold air again! Gonna give it a quick ride and make sure it lasts longer than 5 min like the replaced compressor relay fixed it for...
@@mattmrozinski7820 dont know if youll get this, but when you replaced the relay, did the clutch start spinning again for a few minutes before quitting again? and then using the stick to spin the clutch fixed it? thank you
He’s running power straight to the compressor to see if it kicks on. If it does indeed kick on it’s a problem in the wiring. If the jumper kicks it on the compressor has an open circuit.
Thanks for the great video. You mentioned "jumpering the wires on the switch", which is on the line to the left of the compressor. How do you jumper the wires? Thanks for your help.
Funny thing about these honda AC systems is that it's rarely a major component. Save time and look in the fuse box first and identify the MG Clutch Fuse ( Magnetic Clutch - AC Compressors on Cars are electromagnetic. ) See if it's blown first. Then identify where the AC Compressor Relay is. On the back of the fuse cover it's the one with a snowflake. But, before you purchase that $7.00 ( Seven Dollar ) relay make sure the AC system condenser fan is running right behind the radiator. If they're working buy a new relay. A lot of the relays today are solid state SSR ( look it up - a led's light shines on a light sensitive diode so that a small current controls a larger current just like an electro-mechanical relay ) heat will eventually kill them.
SMA got away with just buffing the rust off the inside plate of the clutch, removed a shim put it back together and Bob's your uncle, done! That being said, this is a great video, I got the same problem on my 2004 SiR and its just sob to get to, I'll do it someday.
thanks for the helpful video. the 4 (12mm) bolts holding the compressor NEEDS to come off or you can't remove the pulley. you didnt say where this alternate ground for the compressor you used is. thanks from Qc, Canada
Hi Random repair, your video is so very helpful. My 2008 civic ac is acting up as well. Ac compressor is ok when is engine cold. However, ac clutch doesn't engage after sitting in traffic and/or outside temperature is higher than 75F. Did a tap on the clutch while engine running and it start engaging again but still will have the same issue after a while. Relay checked out ok. Refrigerant just got recharged. Fans are working when ac button is on. I will check the gap over the weekend. Poorman's idea was to check and adjust shim or do i suspect ac clutch is the culprit or is it something else.... I dont want to fork for a complete compressor if not needed. Your recommendation is very much appreciated!!!
Marvin U checking and shim may work just fine. mine would not turn on no matter what but it was badly corroded due to the salt used during our winter months. Good luck with your repair, keep me posted
Had this problem same car. Compressor broke and so did the temp gauge. I started out by adding freon and changing the relay. Both didn't work. Paid 800 for the compressor and temp gauge. Thing cranks cold air it actually gets to cold.
Just an additional suggestion. It is not necessary IN ALL CASES to change the coil. If the coil gets power and gets magnetized it could be that the clutch worn out itself (much less cost AND LABOR to change it
Thanks for the help. I just completed replacing my clutch. Here are a couple of suggestions. The type of snap ring pliers you require look like this. www.amazon.ca/OTC-4870-Master-Cylinder-Snap-Ring/dp/B00R7OS1E4/ref=sr_1_31?s=hi&ie=UTF8&qid=1530929949&sr=1-31 One other HUGE trick. Getting the clutch pulley off is impossible without moving the compressor..or.. We used a scissor jack and simply pushed the engine sideways on the rubber engine mounts. We were able to move it about 3/8 of an inch which was just enough to remove the clutch pulley. Saved a ton of time removing the compressor (which entails moving the alternator).
that was painful! cold weather states--just get complete compressor and install. 100 buck used. Just need to evac system which i know some people don't have access to but their are ways around that. also never use those power probes- you back feed the wrong wire you can take out modules. seen several taken out on dodge and fords.
I'm trying to bypass the low pressure switch straight from the battery but I don't know which of the three cables I should be jumping into which one of the three straight from the battery to see if the low pressure switch is bad
@anyone with info, my issue is, long story short, had no AC because I had no condenser, finally got it installed, got the correct pag oil in, was only able to fill the Freon with 1-12oz can because the compressor turns right back off, it does NOT quickly cycle on and off as the popular issue found online, it turns on and blows cold for about 5 seconds and shuts off, it does not kick back on for quite a while, when it’s on everything seems to work properly. Long story long, I crashed smashing my front end, luckily not so bad that it totaled the engine, only the radiator was replaced(engine wise) to get back on the road, however once summer came about (I’m in Phoenix, and been dying for months) realized I had no AC. Found someone with a friend willing to check my hoses, the response from that seemed the hoses were good we believed, but there was no condenser!! My mechanic that replaced my radiator didn’t tell me this, but once I found out knew I had to get one. Ordered one, watched videos how to install/see what all I needed, and got everything I needed. Finally was able to get the condenser installed, and only able to fill 1-12oz can of refrigerant because the compressor shut off quickly after turning on, and wouldn’t come back on. Relays and fuses were checked, nothing bad found, the only thing I know that I don’t have on there is the condenser sensor, so with all that info, is there anyone that can lead me in the right direction to get my AC staying on?! I appreciate the help!
2011 Honda fit- Ac compressor clutch will not engage. Applied 12 v at relay socket, this will engage the clutch manually. Bench tested relay, applied 12 v and got continuity across the load side. Tested relay socket with multimeter, on load side, 12v available , other pin has continuity to compressor. On trigger side, constant 12v source ( reversed polarity -12v for some reason) whether or not AC switch is on. Tested pressure sensor on Low side of compressor line with multimeter, continuity checked. Tested temperature protection switch at compressor, continuity checked. Tried disconnecting battery on the car for ECU reset, tested all fuses I could think of, FAN, SUB FAN, MG CLUTCH, AC. There are several relays in the actual fuse box which have no labels, unable to test those because I don't know what they do, auxiliary relay box in engine bay contains 3 relays, fan x2 and AC Clutch, applied 12 v all click when voltage is applied. Totally lost on what to do next, resistance across the clutch coil is 3 ohms and it works when 12v is directly applied either by battery to clutch or jumping the relay socket. Any help would be greatly appreciated.
I cannot get the pulley snap ring off and it is supposedly the easy one! I have tried 3 different sets of pliers and none have worked. Someone suggested Tekton 3576 - that will probably be my next attempt. At this rate, I'll be satisfied just to get the pulley off, as the bearing is the main problem in my case.
sorry for all the question bro, but same way to test as compressor + to red or green wire, sorry im mechanic but no electrician, still can get stuff done.
Random Repair hey man. so i began fixing my ac.. the clutch seemed to be working (it was rotating) but after i restarted my car its not rotating anymore. you know what might cause that and if i can fix it?
I tried to replace the AC compressor clutch with a kit (clutch, belt pulley w/bearing and coil). but could not get at the snap ring clips holding the old ones in place on the compressor shaft. I bought 3 different sets of snap ring pliers, but none worked. These clips are recessed deep inside on the shaft, and the pliers would just barely budge them. I ended up having to replace the entire compressor, as the snap ring removal phase stopped me cold.
As an aside, I inquired at a Pep Boys about replacing the compressor belt pulley bearing. I was told the unit was not replaceable and that the compressor was shot. Not true. Then he wrote up an estimate that included the compressor and drier/receiver, which came to $1200! I threw in a new (Chinese) compressor for about $200, and at least the pulley bearing is now replaced. Next I need to try and recharge the system and see if it holds. No wonder auto mechanics ranks as one of the top areas for consumer complaints - you can't trust what you are being told.
It's likely if you would have checked the clutch gap on the original clutch you would have seen it became too wide so you would have just needed to remove the shim. That would have been all you needed to do. You could have tried to hit the clutch hard with something with the ac on to confirm. It likely would have turned on, which would have been further confirmation. You can get a spanner wrench to hold the pulley to remove the pulley bolt so you can then torque it to spec if there are holes in the clutch for the spanner wrench to go into. Since the fans were running that should be further confirmation the system itself is working properly enough to show the issue is the clutch. If the fans weren't turning on then it would be something else.
the video was not about complete diagnostics since I had figured that out before hand. the clutch was worn out and maybe removing shims would have made it work, but the proper repair was to replace this inexpensive part. thanks for watching and your input!
@Nuo Jin not really, you need to check for continuity at the ac pressure switch to ensure you have enough refrigerant, and it could be the ac control unit itself on the dash
I installed the new coil with the back facing tit aligned with the hole on the plate that it sits flush against, but with the c-clip installed the coil is not held firmly in place by the c-clip. The coil will start to partially rotate when I turn the A/C on and the coil is energized. This will not work like this, I need to figure out how to have the coil firmly fixed in place. The c-clip is correctly installed and sitting in the groove all the around the compressor shaft. There is space between the c-clip and the front face of the coil. Does the coil have to be pressed in? Do I need to use an epoxy to hold the coil in place? Any and all help will be greatly appreciated. Thanks and great video guy's!
King Solomon there's a video how how to grind off some matter inside the clutch you disassemble, or remove a little disk, as the prongs are worns down that engage and hold the clutch...
Hello I'm about to tackle this project for the very first time, after watching your video multiple times I am pretty confident i can compete the task. Just have a few questions, 1. Did you dismount the ac compressor? And 2. Did you have to remove the alternator? Just asking cause I saw other videos and they stated that needed to be done. Thank you for this great content
I've seen a video talking about this issue. it said "your ac blows and you can feel the air flow lessen and lessen caused by the system freezing over." they said the cause was a sensor in the controls in the dash and the control button piece needed replaced. Mine did that, but that was before the compress stopped working.
I have 07 civic also, stops working when it gets warm mostly, good on start up, if parked at idle it keeps clunking like its not turning on. If I rev engine to 3 rpms it will turn on for a little while sometimes. I think the clutch isnt engaging. I replaced the whole system a year ago, except lines ,wiring, and control panel. Makes a hissing vibrating sound when it works driving, I believe when trying to engage clutch.....
@SeverdSeouL Yes, im in Thunder Bay, Ontario Canada. Snow, salt, all that crap. Your doing good if you can have a car look decent and last past 10 years here :)
Thanks for your video. I have the same problem with the AC clutch with my Civic 2007. I don't know if it's the clutch or low refrigerant. I hope to jump the compressor clutch. At around 4:51, the video just briefly mentioned that the clutch didn't turn on even after being powered. It's not very clear to me how to do the powering exactly? Could you please point out again which wires I should tap in order to jump the clutch? Thank you very much.
There is a switch on the line behind the headlight. you can jump that and if its undercharged the ac will turn on. You can also connect a gauge. If fans are running but AC clutch isnt its probably the clutch.
Don't jump the wrong wires on that switch on the AC line, which has 3 wires instead of 2. I did, and the car shut off immediately and is now throwing a P0113 and a P2649 (IAT High input and rocker arm control circuit high). I'm thinking I cooked something in the harness or ECU.
And if this happens to anyone else, it seemingly went away after the car being off for an hour or so. Hopefully it doesn't come back. Was getting ready to start tracing wires. Also, it seems that my coil is fine but my compressor clutch is very corroded. Working the arms on the clutch a bit seems to have freed them up. I've read that for others who just had a rusty clutch, if you spray it with penetrating lubricant, it will resume working. That's assuming your coil's not bad.
The AC on my Honda CIVIC 2010 does not work. It blows hot air only. The clutch engages perfectly I can see it spinning. I checked the gas and it was good, I flushed a little bit in order to be able to put the sealant with the UV in order to detect leaks, none. The compressor stops when it is over charged, I released to the proper quantity, so it engages constantly ( it does not stops and re-engages ) The Lower pressure pipe, it is cold when the AC is running. What else can be?
CGGS1981 sounds like you may have an issue with you hot/cold blend door. a.c. may be working fine but pulling hit air thru the heater core. does the a/c work when you first start the engine cold?
This video has been a HUGE help for fixing my 2008 Honda Civic LX Coupe. One question, though, what specific make/model of Snap Ring Pliers did you use on the innermost ring for the coil. I haven't found one that has worked yet. Thanks in advance.
Hi, can one change the bearing from the clutch housing if its not damaged and beginning to go shot? My AC works fine, but has started being noisy with the typical grinding sound of a worn bearing.
I have a 08 civic mine blows cold and then warm compressor and ac fan cuts on. But the compressor and fan never shuts off for not even a second when the air is on. Maybe im wrong but I thought they were supposed to cut off for at least a few seconds here and there when the system is not stressed. If i drive 60 mph for 30 they run constant. Doesn’t seem right. HELP ME 😳
my 2007 CR-V ac compressor not turning and my condensor fan also not turning. got power 12v to relay coil and pulled the relay and jump it still not turning compressor and fan. could not get the 12 v at compressor. there is about 50 psi on hi and low side line. the only things that i have not verified is hi and low safety switch which has 3 pin and im not sure how to test it. is there any fuses after the relay? thanks
Nick Miller it's probably low on refrigerant, compressor won't kick on if it's low, otherwise it could damage the compressor. pressure on low and high side should be equal when ac not running (pressure equalize).
Nick Miller if it has 3 pins it's a sensor not a switch. It's a thermistor. Takes pressure inside the system and translates it into a voltage that it sends to PCM. take it to shop and get it recharged and checked for leaks.
Hey this is a great video. Wish I had seen this before. I have already replaced my a/c compressor and my a/c is not working. the fan don't turn on and the a/c clutch dose not engage when I turn on the a/c. you mention bypassing the censor. how do you do that. it has three wires which do I bypass?
Yo tengo un problema en mi a/c de mi civic haber si puede ayudarme, lo que pasa es que cuando pisas a fondo el acelerador deja de hechar aire helado,,y dias antes el ac se encendia sin picar ningun boton,
I wish you will try every single situation as damage, for a sample I have I think I have a low pressure switch problem but I'm not sure which cable I should be jumping with the probe not sure if you understand what I mean
Hi-inspired by your video I obtained a clutch rebuild kit and decided to repair my ac myself. Unfortunately, even though I did everything EXACTLY as you did, I can't get the new Clutch Pulley back onto the compressor bearing. The fit is just too tight. I was working on my '07 EX for 8 hours straight today, and two of those 8 hours was spent unsucessfully putting the new pulley on the compressor. I even tried putting the old clutch pulley back on (compressor has been completely unbolted from the motor, just like you did), and still: nothing. Could you help me understand how you did this? Clay
It has to be completely square-yes, I am seeing that that is the problem: that I've not been able to get a completely square push on the pulley. But that begs the question: how did YOU do it ? Did you have your friend hold the compressor is just such a way, while you gave it smacks with your mallet? Another way? Space is impossibly tight down there, and I'm at my wit's end.
Mine whines but my ac works fine 2007 ex civic coupe It makes the noise when I accelerate and you can hear the noise when it’s automatically shifting gears
At 5:15 you point to one red wire then immediately point to the next red wire when you said "this one here" when you're talking about adding power with your power probe. So which one is it? The first wire on the outside or the second wire in the middle?
any advice is welcomed!! I have a 01 honda civic lx that the ac stopped working. I check to see if the ac clutch was kicking on but I noticed It wasn't there!!! would I just need to buy the kit and install it ? NOTE: prior to a drive through car wash my ac was working just fine. no problems. thanks in advance (:
Awesome video. I'm in the process of dx my a/c problem. Was working fine, stopped went into store started up again no ac?? I replaced 2 relays still no AC. Attempted to jump the pressure switch and the clutch DID NOT engage. Also when I turn on max AC the radiator fans do not turn on. My question is the FANS? Should I look at that first or should I stick to replacing the coil and clutch? Thanks for any advice.
First check you're fuses. Pop open the hood, open black fuse box and check fuses. If fuses are fine. See if you can send 12 volts to the AC coil. Unplug power wire to coil, use a long wire with clips on each end. Put one end to battery plus, other end to the coil, if clutch does not engaged, then you have a faulty coil.
what I mean is how do I know without taking it out if my low pressure switch is good I already tried relays, fans coming on fuse compressor start right up from the battery the last thing that I believe is low pressure switch
My Ac guy is telling me the AC pressure switch is the issue.... It works cold then gets hott .. A number of forums tell me its the switch... I ordered the wrong switch from Amazon ... I wanted to know if you could send me an image of what the switch for this should look like ??
If you do it the way they did it, you don't have to evacuate the system because you don't disconnect the AC lines. Getting those snap rings off is not trivial because it's soooooo deep and very little room. My coil went bad and I hired a moonlighting Honda mechanic to fix it.
Hello Randy I am having similar issue. I have an 06 civic and am not able to get to the bolt. So do I have to remove the whole compressor unit out or just remove the 4 bolts to give more space. Someone told me I will have to release all pressure and Freon before I remove anything from the compressor. My issue is i am having weird noise from the belt area and when i removed the serpentine belt the only pulley that made a grinding noise was from the a/c pulley. Could that be it or maybe I need to change the tensionor. any help will be awesome. About to order parts dont want to order something unnecessary. oh I am getting cold air no problem there..it's just the noise and it makes a higher pitch noise when the clutch stops spinning.
Hi, my a/c is gets cold when I recharge but after sometime it blows warm. I checked the a/c clutch and it's working. No leaks and i have enough freon. Dont know what the problem is. Please help
Ruben Ramirez you can take it always and check. if it's only noisy when the compressor is spinning it's probably a bad bearing internally and I would stop using the ac immediately
I have tried to get a long enough snap ring pliers for the coil snap ring... but have been unsuccessful as it is deep with very little space for a regular snap ring pliers. I've tried the channelock one as well, it it is too large to fit in the tiny space. Help!
Spray the snap ring with penetrating oil. Let soak for about 15 minutes, then use a small snap ring pliers. Snap ring is frozed in place from the weather.
What snap ring pliers would you recommend for this coil replacement? The local ones from Autozone and Harbor freight won't reach. Would the Lisle 49200 work?
My compressor spins but my fans don't, and I also don't get a pressure when connecting my refrigerant gauge, what do you think it could be a leak or the relay??
Quick question. Should the clutch engage when you turn on your AC even if there's not refrigerant in the system ? Cause mine doesn't, is empty thou, cause I emptied it when I replace a hose. Should the clutch engage anyways? Thanks for your video very helpful.☺️
I hope you see this message and get back to me before tomorrow morning. How did you remove the belt? Did you have to spring down the idle pulley or just simply loosened the compressor? Just trying to fine the easier way. Thanks.
Hello! The tensioner is spring loaded. When you turn it with a wrench you can pull the belt off. Best of luck with your repair. Take your time, there are a few parts that can be a bit frustrating.
A/C Compressor is always running even when OFF, blows cold air. Any ideas? Already changed the switch 2 1:05, doing that did nothing but originally if I did remove it, compressor would shut off. This all started when I changed the cold aluminum pipe and refilled the A/C, due to a leak.
a619ko could be a sticky relay switch. If I'm not mistaken it also runs when having the defrost option too(if you're wondering in the winter). Late reply I know, did you end up finding a solution?
It could be the panel in the car dash where the a/c on/off buttons are. There is a sensor that is suppose to tell the compressor to shut off. Change the panel.
How can you tell if there is already plenty of refrigerant in it without having to add refrigerant? Can I just buy some and start adding it? In fact, is that the first thing I should do because I read somewhere that the clutch might not be engaging if there's not enough freon/refrigerant/R134A in it. Is this true? And if so, should I first just try to add refrigerant before doing any other diagnostics? In other words, if the air is blowing warm is it more likely that the clutch is not engaging or that there not enough refrigerant in it? Because I would think that if there was some refrigerant in it it would still blow a little bit cool, just based on logic. I'm inquiring for a 2006 Civic.
OldHickory7 you can buy a kit with a guage and put it on the low side. See what the pressure is sitting at. Somewhere around 25 psi the compressor can turn on. If it's less, needs a charge.
mine is very high on the low side(300psi) and baseline somewhat low on the high side(120psi) I think it's the compressor internal valve thats the problem cos these psi readings don't change when i turn the ac. Ive tested everything else. it's a clutchless compressor. all AC tubes lines in the engine bay are same temperature even in and out the expansion valve area. any help???
So a year ago I bought all the components need to replace the A/C compressor and associated components on my 2006 Honda Civic. Needless to say I was highly pleased when the A/C worked upon initial startup. Great! Well this lasted for a couple of weeks or so then no longer worked. I chalked it up to a failed amateur effort to refit, vacuum and fill my A/C. Some months later I decided to revisit the issue (hot weather and a hot car motivates you) and ran across an article that said give the A/C compressor switch a moderate whack with a screwdriver handle etc. and if the compressor kicks on then bingo their is your failed component. A/C still going strong a month or so later. If only everything could be so simple to resolve. :) amzn.to/35gEDRg
Does anyone know if the coil could be working intermittently depending on temperature? My a/c works fine(car has freon, no leaks) when just starting out cold engine, lower ambient air temps, but as the ambient temperature starts getting into the 90's I have pulled over and visually seen the compressor clutch not engaged, but both fans are still spining. I have ruled out the compressor temp sensor, by shorting two of those three wires on the connector on the alt. Thinking I have a break in the coil, will confirm with ohm reading.
Sean Ashcraft remove the clutch and get rid of washer. The clutch must be worn out so it most not be engaging at high temp. Reduce the difference by getting rid of any washer. This is what i found on google by someone having same issue and they fixed the issue just be removing any washer
I know this is an old video but my daughter just purchased an '07 civic ex and is having the same issue. Where can I purchase an a/c clutch? It's packaged with a compressor everywhere I've looked.
+Sensei Mind You are so right , brother, that is usually all it is!!! That relay, #12 in fusebox, in engine department, cost $5.99 in Advange Auto Parts, so do that first, done it, bad reley, by the way: Made in USA ;o)
Awesome video dude! But how did u take out the snap ring that is on the coil? I am having an awfully hard time removing that snap ring. The snap ring for the pully took me literally 2 min. Thanks for the help!
+Random Repair would u think this pair of pliers will work GearWrench 82033 Double X External Snap Ring Pliers www.amazon.com/dp/B001M0O1KM/ref=cm_sw_r_cp_api_8KEAxbPA4PZSA
called a Honda dealership and asked how much to remove a shim. they said $791. I laughed, watched your video and for $22 bucks and 3 hours with the wrong tools, did it myself. my bank account thanks you, man!
scaife1217 let not play dumb. Dealership is a business w costs and liability. of course its going to cost big bucks if they fix it vs DIY.
$100/hr mechanics time still would only be ~ $300.
I usually go to Honda to get something diagnosed then buy an aftermarket replacement and get a mom/pop garage to install it for cheaper lol
@tylerthegeek28 will Honda do an AC diagnostic for free, and find the actual problem? Without any agreement to fix it with them? I’ve been searching online for my issue, and can’t seem to find the exact same problem..plus my mechanic took that probe tool and checked my relays with nothing showing wrong.
Most likely not, pretty much once they pop the hood you'll be paying. It would probably be around $100 for them to do a diagnostic but there is no guarantee they will find anything within 30-60 minutes they have the car then they'll start charging you more for taking things apart or off the car etc. Honda wanted almost $800 in labor to replace my AC compressor it would have costed almost $1700 using "genuine" Honda parts. I bought parts from NAPA and had them installed for $400 cheaper then the dealer
Thank you so much for posting this video I had the same problem with my 07 and thanks to this video my A/C is running like new again. Took me about 10 hours but saved myself well over 1000 bucks in labor. I also changed out the serpentine belt too.
good job! clutches are common failures on thes
Update on snap rings. Completed this replacement on my 03 accord. Everything was the same except for the clutch plate design. I purchased a set of Craftsman 2" pliers 9-47412. Unbolt the compressor to reach the ring notch which was at 2 o'clock position. I was able to get the grounding bolt out and replaced with a std bolt 5mm x 8mm. AC's back in business. Thanks guys for a great video instruction
Hey guys, giving you heads up. I've finally fixed my 08' civic. AC is now blowing ice cold air. You're video saved me $900 in labor cost, that coil replacement was a pain to take out. Thanks for the video, really helped me, only if you guys lived close to the New Orleans Louisiana area, I would have treated you guys to lunch. Lol. Now I don't have to sweat my balls off this summer like I did last year. Thanks again, God bless.
Awesome news!
If I lived closer I would have helped! HAHA
Good job on repairing your car
Yay.. my car's A/C is fixed :-) Eric from South Main Auto walked me through my exact problem. My A/C would run for about 10 minutes and quit.. then blow warm air. I took my car to a local shop and they recharged the system ($40)... issue remained. Then they replaced the condenser (which looked like Swiss cheese $400)... issue remained... GRRRRrrrrr. So I turned to youtube and I fixed the A/C clutch ($0) and the issue is FIXED! Thanks for being my virtual mentor Eric :-)
Eric from South main is one of my favorites. His vid3os are amazing
can you link me or tell me the title of that video? I watch Eric's videos but don't think I have seen that one.
Thank You! Excellent information and video; Very Helpful in guiding me in replacing the A/C clutch on my '06 Civic. I learned a lot from reader comments and wanted to contribute in an effort to assist others.
- Straight forward repair (with the help of this video). However re-installing the inner larger snap ring which secures the electromagnetic coil to the compressor nearly did me in! Not too hard to remove it but Very Difficult to re-install. I found reusing the original Honda snap ring was helpful. It was easier to work with than the ring that came in my clutch kit. It has smaller holes for the tool to fit into, has a slightly larger gap, and wasn't as prone to twisting when fully expanded. The snap ring tool that worked for me (although not a quality tool) is the straight-external tool from this kit - TEKTON 3576 Internal / External Snap Ring Pliers Set, 4-Piece. To work for this repair the tool needs to have long needle-nose like ends, which give you some working room between the coil and compressor shaft.
- Snap ring tools I tried that did NOT work for me in this tight space are: GearWrench 82033 Double X External Snap Ring Pliers and Channellock 927 8-Inch Retaining Ring Plier.
- On the '06 Civic if you also change the serpentine belt please note Honda Service Bulletin 06-059. Your replacement belt will be longer than the original and needs to be routed differently.
- In my case the A/C compressor had to be unbolted from the engine to allow enough space to remove the clutch (it hits the frame otherwise). There are 4 bolts holding the compressor to the motor; the two on the bottom are easy to spot and the two on the top can be found next to the inlet and outlet compressor hoses. All 4 bolts are long and come in from the front.
- The philips head screw holding the coil grounding wire is an M4 and 8 - 10 mm in length.
- I was surprised to learn that the cost of a replacement compressor with clutch was roughly $300 (US). I was so-stuck on the inner snap ring that I considered replacing the whole unit and paying for a system vacuum/recharge ($135 US).
Hope this information is helpful!
Hey man, thanks for the model of your pliers. . I am stuck trying to get that inner snap ring off, my $13 pair of snap ring pliers from a local store can't get it. I'll try yours
Hello Randy I am having similar issue. I have an 06 civic and am not able to get to the bolt. So do I have to remove the whole compressor unit out or just remove the 4 bolts to give more space. Someone told me I will have to release all pressure and Freon before I remove anything from the compressor. My issue is i am having weird noise from the belt area and when i removed the serpentine belt the only pulley that made a grinding noise was from the a/c pulley. Could that be it or maybe I need to change the tensionor. any help will be awesome. About to order parts dont want to order something unnecessary. oh I am getting cold air no problem there..it's just the noise and it makes a higher pitch noise when the clutch stops spinning.

just remove the 4 bolts and the compressor will be kind of hanging by the coolant lines. no need to disconnect them
i found that the compressor bolts are a lot easier to get to if you pull the fan. Two bolts at the top, wire harness disconnect and the fan will lift out. It's a little tricky to snake out, so be careful not to damage the radiator while you pull the fan. Once the fan is out, it is much easier to get to the bolts.. from the top.
Thanks for this video. It helped me out tremendously to replace my civic 08 ac clutch. Cold air!!!!!
So did you have to replace the entire compressor or just the clutch?
Thank you very much for taking the time to document, much appreciated!
Dan Ginney you are very welcome
thanks guys I'm up against an ac problem in an 06 civic just down the road in petawawa. never worked on the ac before so this was a big help.
good luck with your repair!
Hopefully your repair goes easier then mine did. The front snap ring was a*itch to get to, had to borrow a set of snap ring pliers from a friend. Finally got it out and then focused on getting the pulley off, it took alot of beating and banging and a few choice words, spent almost a full day on getting it off. Came real close to pulling the whole damn thing off so I could work on it. Hub pullers unless it is a very small/narrrow one won't fit in the confined space.
The snap ring on the outer side has a very small diameter hole. The inner has a larger hole. I had to use two different pliers to access each one. Good luck if you choose to start this repair,
Thanks for the video! I already confirmed this to be my issue, but it was nice to see it step by step!
Or for those without multimeter, Carefully take long broom handle and help (push) activate clutch while ac turned on. The gap is so sensitive
Gary White thanks!
My clutch was apparently seized (or something, it wasn't turning on with the fan or AC when switched ON, didn't engage, I replaced the Relay switch but it still didn't engage). I poked it with a long stick (car & AC off) and it started to spin! Cold air again! Gonna give it a quick ride and make sure it lasts longer than 5 min like the replaced compressor relay fixed it for...
@@mattmrozinski7820 dont know if youll get this, but when you replaced the relay, did the clutch start spinning again for a few minutes before quitting again? and then using the stick to spin the clutch fixed it? thank you
what does it mean to "jumper" the line? connect the two wires to short them to each other?
He’s running power straight to the compressor to see if it kicks on. If it does indeed kick on it’s a problem in the wiring. If the jumper kicks it on the compressor has an open circuit.
Thanks for the great video. You mentioned "jumpering the wires on the switch", which is on the line to the left of the compressor. How do you jumper the wires? Thanks for your help.
Funny thing about these honda AC systems is that it's rarely a major component. Save time and look in the fuse box first and identify the MG Clutch Fuse ( Magnetic Clutch - AC Compressors on Cars are electromagnetic. ) See if it's blown first. Then identify where the AC Compressor Relay is. On the back of the fuse cover it's the one with a snowflake. But, before you purchase that $7.00 ( Seven Dollar ) relay make sure the AC system condenser fan is running right behind the radiator. If they're working buy a new relay. A lot of the relays today are solid state SSR ( look it up - a led's light shines on a light sensitive diode so that a small current controls a larger current just like an electro-mechanical relay ) heat will eventually kill them.
L G what do I do if my AC condenser fan is not running and the compressor is not engaging?
Yeah What Of Condenser Fans Not Running Or Clutch Isn’t Engaging ???
Thanks for taking the time to make this video.
thanks for taking the time to watch!
Well I been stuck on the snap ring for 2 days... hopefully I have better luck tomorrow
SMA got away with just buffing the rust off the inside plate of the clutch, removed a shim put it back together and Bob's your uncle, done! That being said, this is a great video, I got the same problem on my 2004 SiR and its just sob to get to, I'll do it someday.
Yeah might have worked just fine idk. Replacing it is pretty easy :)
2005 civic here. Clutch not engaging. I checked for ground and hot RIGHT AT THE CONNECTION TO THE CLUTCH,Proof positive is kaput. Time to make a plan
Followed this! Got AC NOW! "Blows Cold air"
Roberto Perez perfect!!!
Thanks!
Don't spin the compressor backwards when you take the nut off. It can damage the compressor.
thanks for the helpful video.
the 4 (12mm) bolts holding the compressor NEEDS to come off or you can't remove the pulley.
you didnt say where this alternate ground for the compressor you used is.
thanks from Qc, Canada
Hi Random repair,
your video is so very helpful. My 2008 civic ac is acting up as well. Ac compressor is ok when is engine cold. However, ac clutch doesn't engage after sitting in traffic and/or outside temperature is higher than 75F.
Did a tap on the clutch while engine running and it start engaging again but still will have the same issue after a while.
Relay checked out ok. Refrigerant just got recharged. Fans are working when ac button is on.
I will check the gap over the weekend.
Poorman's idea was to check and adjust shim or do i suspect ac clutch is the culprit or is it something else....
I dont want to fork for a complete compressor if not needed.
Your recommendation is very much appreciated!!!
Marvin U checking and shim may work just fine. mine would not turn on no matter what but it was badly corroded due to the salt used during our winter months. Good luck with your repair, keep me posted
Had this problem same car. Compressor broke and so did the temp gauge. I started out by adding freon and changing the relay. Both didn't work. Paid 800 for the compressor and temp gauge. Thing cranks cold air it actually gets to cold.
Just an additional suggestion. It is not necessary IN ALL CASES to change the coil. If the coil gets power and gets magnetized it could be that the clutch worn out itself (much less cost AND LABOR to change it
Thanks for the help. I just completed replacing my clutch. Here are a couple of suggestions. The type of snap ring pliers you require look like this.
www.amazon.ca/OTC-4870-Master-Cylinder-Snap-Ring/dp/B00R7OS1E4/ref=sr_1_31?s=hi&ie=UTF8&qid=1530929949&sr=1-31
One other HUGE trick. Getting the clutch pulley off is impossible without moving the compressor..or..
We used a scissor jack and simply pushed the engine sideways on the rubber engine mounts. We were able to move it about 3/8 of an inch which was just enough to remove the clutch pulley. Saved a ton of time removing the compressor (which entails moving the alternator).
that was painful! cold weather states--just get complete compressor and install. 100 buck used. Just need to evac system which i know some people don't have access to but their are ways around that. also never use those power probes- you back feed the wrong wire you can take out modules. seen several taken out on dodge and fords.
Brian Fitz thanks! it's all good
I'm trying to bypass the low pressure switch straight from the battery but I don't know which of the three cables I should be jumping into which one of the three straight from the battery to see if the low pressure switch is bad
so which of the three connectors needed to be jumped?
@@gloriacarmelitacastillo2257 Did anyone find out which two needed to be jumped? There are three wires.
@anyone with info, my issue is, long story short, had no AC because I had no condenser, finally got it installed, got the correct pag oil in, was only able to fill the Freon with 1-12oz can because the compressor turns right back off, it does NOT quickly cycle on and off as the popular issue found online, it turns on and blows cold for about 5 seconds and shuts off, it does not kick back on for quite a while, when it’s on everything seems to work properly.
Long story long, I crashed smashing my front end, luckily not so bad that it totaled the engine, only the radiator was replaced(engine wise) to get back on the road, however once summer came about (I’m in Phoenix, and been dying for months) realized I had no AC. Found someone with a friend willing to check my hoses, the response from that seemed the hoses were good we believed, but there was no condenser!! My mechanic that replaced my radiator didn’t tell me this, but once I found out knew I had to get one. Ordered one, watched videos how to install/see what all I needed, and got everything I needed. Finally was able to get the condenser installed, and only able to fill 1-12oz can of refrigerant because the compressor shut off quickly after turning on, and wouldn’t come back on. Relays and fuses were checked, nothing bad found, the only thing I know that I don’t have on there is the condenser sensor, so with all that info, is there anyone that can lead me in the right direction to get my AC staying on?! I appreciate the help!
Would've been nice to see how you jumped the relay to get the compressor to turn on.
2011 Honda fit- Ac compressor clutch will not engage. Applied 12 v at relay socket, this will engage the clutch manually. Bench tested relay, applied 12 v and got continuity across the load side. Tested relay socket with multimeter, on load side, 12v available , other pin has continuity to compressor. On trigger side, constant 12v source ( reversed polarity -12v for some reason) whether or not AC switch is on. Tested pressure sensor on Low side of compressor line with multimeter, continuity checked. Tested temperature protection switch at compressor, continuity checked. Tried disconnecting battery on the car for ECU reset, tested all fuses I could think of, FAN, SUB FAN, MG CLUTCH, AC. There are several relays in the actual fuse box which have no labels, unable to test those because I don't know what they do, auxiliary relay box in engine bay contains 3 relays, fan x2 and AC Clutch, applied 12 v all click when voltage is applied.
Totally lost on what to do next, resistance across the clutch coil is 3 ohms and it works when 12v is directly applied either by battery to clutch or jumping the relay socket.
Any help would be greatly appreciated.

I cannot get the pulley snap ring off and it is supposedly the easy one! I have tried 3 different sets of pliers and none have worked. Someone suggested Tekton 3576 - that will probably be my next attempt. At this rate, I'll be satisfied just to get the pulley off, as the bearing is the main problem in my case.
Timetryp with a decent set they aren't crazy hard. If your in the salt belt they can be rusted
sorry for all the question bro, but same way to test as compressor + to red or green wire, sorry im mechanic but no electrician, still can get stuff done.
Thank You! Great Video.
Randy Graves thank u
thanks for this.
with lots of love from southern Ontario
mojojojo911 thank you!! Hot day here today
Random Repair hey man. so i began fixing my ac.. the clutch seemed to be working (it was rotating) but after i restarted my car its not rotating anymore. you know what might cause that and if i can fix it?
mojojojo911 try tapping it with screwdriver handle. Might be shimmed loose
Wish me luck, I am fixing to do my AC coil tomorrow on a 2008 Honda civic. Same repair as this video. :-\
Good luck my friend!
I tried to replace the AC compressor clutch with a kit (clutch, belt pulley w/bearing and coil). but could not get at the snap ring clips holding the old ones in place on the compressor shaft. I bought 3 different sets of snap ring pliers, but none worked. These clips are recessed deep inside on the shaft, and the pliers would just barely budge them. I ended up having to replace the entire compressor, as the snap ring removal phase stopped me cold.
Timetryp they are really, really annoying. Glad u fixed it
As an aside, I inquired at a Pep Boys about replacing the compressor belt pulley bearing. I was told the unit was not replaceable and that the compressor was shot. Not true. Then he wrote up an estimate that included the compressor and drier/receiver, which came to $1200! I threw in a new (Chinese) compressor for about $200, and at least the pulley bearing is now replaced. Next I need to try and recharge the system and see if it holds. No wonder auto mechanics ranks as one of the top areas for consumer complaints - you can't trust what you are being told.
I replaced the relay for $5.99. When a good one was installed, there is an audible "click". Saving this is the clutch goes out.
It's likely if you would have checked the clutch gap on the original clutch you would have seen it became too wide so you would have just needed to remove the shim. That would have been all you needed to do. You could have tried to hit the clutch hard with something with the ac on to confirm. It likely would have turned on, which would have been further confirmation. You can get a spanner wrench to hold the pulley to remove the pulley bolt so you can then torque it to spec if there are holes in the clutch for the spanner wrench to go into.
Since the fans were running that should be further confirmation the system itself is working properly enough to show the issue is the clutch. If the fans weren't turning on then it would be something else.
the video was not about complete diagnostics since I had figured that out before hand.
the clutch was worn out and maybe removing shims would have made it work, but the proper repair was to replace this inexpensive part.
thanks for watching and your input!
@Nuo Jin not really, you need to check for continuity at the ac pressure switch to ensure you have enough refrigerant, and it could be the ac control unit itself on the dash
@Nuo Jin even if the clutch relay was bad, the fans would still turn on
I’m getting a signal from the dealership stay away , however many good mechanics work under tough management
I installed the new coil with the back facing tit aligned with the hole on the plate that it sits flush against, but with the c-clip installed the coil is not held firmly in place by the c-clip. The coil will start to partially rotate when I turn the A/C on and the coil is energized. This will not work like this, I need to figure out how to have the coil firmly fixed in place. The c-clip is correctly installed and sitting in the groove all the around the compressor shaft. There is space between the c-clip and the front face of the coil. Does the coil have to be pressed in? Do I need to use an epoxy to hold the coil in place? Any and all help will be greatly appreciated. Thanks and great video guy's!
So what if they clutch working intermittently? I changed the relay, but it still works on occasion. Could it be a fuse?
King Solomon there's a video how how to grind off some matter inside the clutch you disassemble, or remove a little disk, as the prongs are worns down that engage and hold the clutch...
Nice tutorial. Thank-you.
Hello I'm about to tackle this project for the very first time, after watching your video multiple times I am pretty confident i can compete the task. Just have a few questions, 1. Did you dismount the ac compressor? And 2. Did you have to remove the alternator? Just asking cause I saw other videos and they stated that needed to be done. Thank you for this great content
Hi. Which wires should be 'jumped' on the low pressure switch.....there is a red, a green and a black wire. Thanks.
2007 civic a/c pressure sensor is a three wire sensor. it can't be jumped
or can it..
?
Really wish there was a serious answer to this...
Power, ground, reference. Which way do you think you jump it lol.
also has major issues with the actual fan switche in the dash causing a sensor to shut down when the compressor freezes up.
could you explain what you mean in this comment? I am trying to troubleshoot my own AC. Fans don't spin and AC blows hot.
I've seen a video talking about this issue. it said "your ac blows and you can feel the air flow lessen and lessen caused by the system freezing over." they said the cause was a sensor in the controls in the dash and the control button piece needed replaced. Mine did that, but that was before the compress stopped working.
I have 07 civic also, stops working when it gets warm mostly, good on start up, if parked at idle it keeps clunking like its not turning on. If I rev engine to 3 rpms it will turn on for a little while sometimes. I think the clutch isnt engaging. I replaced the whole system a year ago, except lines ,wiring, and control panel. Makes a hissing vibrating sound when it works driving, I believe when trying to engage clutch.....
Mine doesn’t have any air coming on at all only when driving at high speeds it will turn on after a few minutes. Help
@SeverdSeouL
Yes, im in Thunder Bay, Ontario Canada. Snow, salt, all that crap. Your doing good if you can have a car look decent and last past 10 years here :)
Random Repair hey would you be so kind, if you would be able to provide the link to the clutch kit you purchased on ebay thank you God Bless!
+carlitos220 you can go to a Honda dealership, parts department will have the coil and clutch sold separately.
Thunder Bolt works wonders boys-lube and le soak; a dry job is unnecessarily tough. I live in Cleveland-capitol of salt and rust
Thanks for your video. I have the same problem with the AC clutch with my Civic 2007. I don't know if it's the clutch or low refrigerant. I hope to jump the compressor clutch. At around 4:51, the video just briefly mentioned that the clutch didn't turn on even after being powered. It's not very clear to me how to do the powering exactly? Could you please point out again which wires I should tap in order to jump the clutch? Thank you very much.
There is a switch on the line behind the headlight. you can jump that and if its undercharged the ac will turn on. You can also connect a gauge. If fans are running but AC clutch isnt its probably the clutch.
I knew from the start it was the AC clutch, spacer or shim as well as coil. Over time, they wear out and the clearance increases.
Don't jump the wrong wires on that switch on the AC line, which has 3 wires instead of 2. I did, and the car shut off immediately and is now throwing a P0113 and a P2649 (IAT High input and rocker arm control circuit high). I'm thinking I cooked something in the harness or ECU.
And if this happens to anyone else, it seemingly went away after the car being off for an hour or so. Hopefully it doesn't come back. Was getting ready to start tracing wires.
Also, it seems that my coil is fine but my compressor clutch is very corroded. Working the arms on the clutch a bit seems to have freed them up. I've read that for others who just had a rusty clutch, if you spray it with penetrating lubricant, it will resume working. That's assuming your coil's not bad.
how did you do it? and what did you do wrong?
The AC on my Honda CIVIC 2010 does not work.
It blows hot air only.
The clutch engages perfectly I can see it spinning.
I checked the gas and it was good, I flushed a little bit in order to be able to put the sealant with the UV in order to detect leaks, none.
The compressor stops when it is over charged, I released to the proper quantity, so it engages constantly ( it does not stops and re-engages )
The Lower pressure pipe, it is cold when the AC is running.
What else can be?
CGGS1981 sounds like you may have an issue with you hot/cold blend door. a.c. may be working fine but pulling hit air thru the heater core. does the a/c work when you first start the engine cold?
Relay is a common problem on these cars. Why wouldnt you have tested that first.
This video has been a HUGE help for fixing my 2008 Honda Civic LX Coupe. One question, though, what specific make/model of Snap Ring Pliers did you use on the innermost ring for the coil. I haven't found one that has worked yet. Thanks in advance.
I used a kit of snap on rings. Its a good idea to have an assortment, and even with that its trial and error
Random Repair Thanks again. Taking your advice and getting a quality set.
Hi, can one change the bearing from the clutch housing if its not damaged and beginning to go shot? My AC works fine, but has started being noisy with the typical grinding sound of a worn bearing.
I have a 08 civic mine blows cold and then warm compressor and ac fan cuts on. But the compressor and fan never shuts off for not even a second when the air is on. Maybe im wrong but I thought they were supposed to cut off for at least a few seconds here and there when the system is not stressed. If i drive 60 mph for 30 they run constant. Doesn’t seem right. HELP ME 😳
Mine Engaged With My Probe At 12 Volts But When I Press Ac The Fans Don’t Come On Or The Ac Compressor . It Has Been Vacuumed & Recharged.
my 2007 CR-V ac compressor not turning and my condensor fan also not turning.
got power 12v to relay coil and pulled the relay and jump it still not turning compressor and fan.
could not get the 12 v at compressor. there is about 50 psi on hi and low side line.
the only things that i have not verified is hi and low safety switch which has 3 pin and im not sure how to test it.
is there any fuses after the relay?
thanks
Nick Miller it's probably low on refrigerant, compressor won't kick on if it's low, otherwise it could damage the compressor. pressure on low and high side should be equal when ac not running (pressure equalize).
Nick Miller if it has 3 pins it's a sensor not a switch. It's a thermistor. Takes pressure inside the system and translates it into a voltage that it sends to PCM. take it to shop and get it recharged and checked for leaks.
Hey this is a great video. Wish I had seen this before. I have already replaced my a/c compressor and my a/c is not working. the fan don't turn on and the a/c clutch dose not engage when I turn on the a/c. you mention bypassing the censor. how do you do that. it has three wires which do I bypass?
Look at other comments above. I think they said middle red wire.
Yo tengo un problema en mi a/c de mi civic haber si puede ayudarme, lo que pasa es que cuando pisas a fondo el acelerador deja de hechar aire helado,,y dias antes el ac se encendia sin picar ningun boton,
I wish you will try every single situation as damage, for a sample I have I think I have a low pressure switch problem but I'm not sure which cable I should be jumping with the probe not sure if you understand what I mean
sorry. I'm not following.
Hi-inspired by your video I obtained a clutch rebuild kit and decided to repair my ac myself. Unfortunately, even though I did everything EXACTLY as you did, I can't get the new Clutch Pulley back onto the compressor bearing. The fit is just too tight. I was working on my '07 EX for 8 hours straight today, and two of those 8 hours was spent unsucessfully putting the new pulley on the compressor. I even tried putting the old clutch pulley back on (compressor has been completely unbolted from the motor, just like you did), and still: nothing.
Could you help me understand how you did this?

Clay Pruitt the fit is tight and it has to be completely square when installing or it will bind. Don't give up!
It has to be completely square-yes, I am seeing that that is the problem: that I've not been able to get a completely square push on the pulley. But that begs the question: how did YOU do it ? Did you have your friend hold the compressor is just such a way, while you gave it smacks with your mallet? Another way? Space is impossibly tight down there, and I'm at my wit's end.
Mine whines but my ac works fine 2007 ex civic coupe
It makes the noise when I accelerate and you can hear the noise when it’s automatically shifting gears
Hopefully it just keeps going :)
Any advice or tips to rid myself of this noise?
All my fluids especially transmission is ok no leaks
😞☹️
At 5:15 you point to one red wire then immediately point to the next red wire when you said "this one here" when you're talking about adding power with your power probe. So which one is it? The first wire on the outside or the second wire in the middle?
Tim Olvera it's the one I point to. Middle of memory serves but I would suggest a quick continuity test to confirm
PLEASE HELP! Where did you put your ground wire?
any advice is welcomed!!
I have a 01 honda civic lx that the ac stopped working. I check to see if the ac clutch was kicking on but I noticed It wasn't there!!! would I just need to buy the kit and install it ?
NOTE: prior to a drive through car wash my ac was working just fine. no problems. thanks in advance (:
Awesome video. I'm in the process of dx my a/c problem. Was working fine, stopped went into store started up again no ac?? I replaced 2 relays still no AC. Attempted to jump the pressure switch and the clutch DID NOT engage. Also when I turn on max AC the radiator fans do not turn on. My question is the FANS? Should I look at that first or should I stick to replacing the coil and clutch? Thanks for any advice.
First check you're fuses. Pop open the hood, open black fuse box and check fuses. If fuses are fine. See if you can send 12 volts to the AC coil. Unplug power wire to coil, use a long wire with clips on each end. Put one end to battery plus, other end to the coil, if clutch does not engaged, then you have a faulty coil.
How did you "jumper" the switch?
what I mean is how do I know without taking it out if my low pressure switch is good I already tried relays, fans coming on fuse compressor start right up from the battery the last thing that I believe is low pressure switch
Middle wire and red wire.
More likely you are low on refrigerant due to a leak :)
My Ac guy is telling me the AC pressure switch is the issue.... It works cold then gets hott .. A number of forums tell me its the switch... I ordered the wrong switch from Amazon ... I wanted to know if you could send me an image of what the switch for this should look like ??
Good video and thx for it, but... Would it be better replacing the whole part, (ac compressor price at junk its only 60)
If you do it the way they did it, you don't have to evacuate the system because you don't disconnect the AC lines. Getting those snap rings off is not trivial because it's soooooo deep and very little room.
My coil went bad and I hired a moonlighting Honda mechanic to fix it.
Hello Randy I am having similar issue. I have an 06 civic and am not able to get to the bolt. So do I have to remove the whole compressor unit out or just remove the 4 bolts to give more space. Someone told me I will have to release all pressure and Freon before I remove anything from the compressor. My issue is i am having weird noise from the belt area and when i removed the serpentine belt the only pulley that made a grinding noise was from the a/c pulley. Could that be it or maybe I need to change the tensionor. any help will be awesome. About to order parts dont want to order something unnecessary. oh I am getting cold air no problem there..it's just the noise and it makes a higher pitch noise when the clutch stops spinning.
Hi, my a/c is gets cold when I recharge but after sometime it blows warm. I checked the a/c clutch and it's working. No leaks and i have enough freon. Dont know what the problem is. Please help
Could be a few things but sounds most likely like it's freezing up. Could be under charged, bad airflow, or an electronic issue
@@randomrepair1680 thanks
thanks, do think if I get the for $45 it will work because I think just the bearing is bad
Ruben Ramirez you can take it always and check. if it's only noisy when the compressor is spinning it's probably a bad bearing internally and I would stop using the ac immediately
my a.c on my 2006 civic is making a horrible noise when the a.c is on and the clutch engages. could that be the clutch bearing?
I have tried to get a long enough snap ring pliers for the coil snap ring... but have been unsuccessful as it is deep with very little space for a regular snap ring pliers. I've tried the channelock one as well, it it is too large to fit in the tiny space. Help!
Spray the snap ring with penetrating oil. Let soak for about 15 minutes, then use a small snap ring pliers. Snap ring is frozed in place from the weather.

What snap ring pliers would you recommend for this coil replacement? The local ones from Autozone and Harbor freight won't reach. Would the Lisle 49200 work?
My compressor spins but my fans don't, and I also don't get a pressure when connecting my refrigerant gauge, what do you think it could be a leak or the relay??
Quick question. Should the clutch engage when you turn on your AC even if there's not refrigerant in the system ? Cause mine doesn't, is empty thou, cause I emptied it when I replace a hose. Should the clutch engage anyways?
Thanks for your video very helpful.☺️
It won't turn on unless there is an adequate charge :)
@@randomrepair1680
Got it, thank you much.
i have Honda civic ex 2002 and i think have the problem because the ac make noise how much will cost to repair it
Tanks for the video. How did you reconnect the red wires together, just crimped them?
Hi.
There were connectors on them :)
I hope you see this message and get back to me before tomorrow morning. How did you remove the belt? Did you have to spring down the idle pulley or just simply loosened the compressor? Just trying to fine the easier way. Thanks.
Hello! The tensioner is spring loaded. When you turn it with a wrench you can pull the belt off.
Best of luck with your repair. Take your time, there are a few parts that can be a bit frustrating.
Random Repair thanks you so much.
A/C Compressor is always running even when OFF, blows cold air.
Any ideas? Already changed the switch 2 1:05, doing that did nothing but originally if I did remove it, compressor would shut off. This all started when I changed the cold aluminum pipe and refilled the A/C, due to a leak.
a619ko could be a sticky relay switch. If I'm not mistaken it also runs when having the defrost option too(if you're wondering in the winter). Late reply I know, did you end up finding a solution?
It could be the panel in the car dash where the a/c on/off buttons are. There is a sensor that is suppose to tell the compressor to shut off. Change the panel.
How can you tell if there is already plenty of refrigerant in it without having to add refrigerant? Can I just buy some and start adding it? In fact, is that the first thing I should do because I read somewhere that the clutch might not be engaging if there's not enough freon/refrigerant/R134A in it. Is this true? And if so, should I first just try to add refrigerant before doing any other diagnostics? In other words, if the air is blowing warm is it more likely that the clutch is not engaging or that there not enough refrigerant in it? Because I would think that if there was some refrigerant in it it would still blow a little bit cool, just based on logic. I'm inquiring for a 2006 Civic.
OldHickory7 you can buy a kit with a guage and put it on the low side. See what the pressure is sitting at. Somewhere around 25 psi the compressor can turn on. If it's less, needs a charge.
mine is very high on the low side(300psi) and baseline somewhat low on the high side(120psi) I think it's the compressor internal valve thats the problem cos these psi readings don't change when i turn the ac. Ive tested everything else. it's a clutchless compressor. all AC tubes lines in the engine bay are same temperature even in and out the expansion valve area. any help???
I would say you have a bad compressor with those numbers.
Doesn't everyone replace the whole compressor/clutch assembly? What if you did all of this and the compressor was bad?
Clutch bad and compressor internals? That would be a bad day
So a year ago I bought all the components need to replace the A/C compressor and associated components on my 2006 Honda Civic. Needless to say I was highly pleased when the A/C worked upon initial startup. Great! Well this lasted for a couple of weeks or so then no longer worked. I chalked it up to a failed amateur effort to refit, vacuum and fill my A/C. Some months later I decided to revisit the issue (hot weather and a hot car motivates you) and ran across an article that said give the A/C compressor switch a moderate whack with a screwdriver handle etc. and if the compressor kicks on then bingo their is your failed component. A/C still going strong a month or so later. If only everything could be so simple to resolve. :)

Does anyone know if the coil could be working intermittently depending on temperature? My a/c works fine(car has freon, no leaks) when just starting out cold engine, lower ambient air temps, but as the ambient temperature starts getting into the 90's I have pulled over and visually seen the compressor clutch not engaged, but both fans are still spining. I have ruled out the compressor temp sensor, by shorting two of those three wires on the connector on the alt. Thinking I have a break in the coil, will confirm with ohm reading.
Sean Ashcraft remove the clutch and get rid of washer. The clutch must be worn out so it most not be engaging at high temp. Reduce the difference by getting rid of any washer. This is what i found on google by someone having same issue and they fixed the issue just be removing any washer
I know this is an old video but my daughter just purchased an '07 civic ex and is having the same issue. Where can I purchase an a/c clutch? It's packaged with a compressor everywhere I've looked.
I bought mine from eBay.
I would imagine it's still available
First look at the compressor if it turning and fan is turning It could be the compressor relay fuse, so replace it.
+Sensei Mind You are so right , brother, that is usually all it is!!! That relay, #12 in fusebox, in engine department, cost $5.99 in Advange Auto Parts, so do that first, done it, bad reley, by the way: Made in USA ;o)
+Eero Laukkanen
We dont ever replace anything without testing first... Thats usually a waste of money. A relay is very easy to test :)
Mine was a relay problem......yes.
the link said ended, but I found other but I don't know what kinda car is my if it is Dx lx
Awesome video dude! But how did u take out the snap ring that is on the coil? I am having an awfully hard time removing that snap ring. The snap ring for the pully took me literally 2 min.
Thanks for the help!
you need an interesting assortment of snap ring pliers and an awful lot of patience. I have faith in you!
+Random Repair would u think this pair of pliers will work

+westin lee I would definitely say so. best of luck
+Random Repair my man, thank you!
+westin lee anytime buddy.
Which two wires do you jump? It has three wires.
Thanks for sharing.
Just to add to the knowledge base I have two of these cars and both of them had failed A/C clutch relays. Easy fix.
always a good item to check!
Great video, where can I find the replacement part you're using? My apologies if this has already been answered...
Matthew Alexandre I found them on eBay. Try searching civic compressor clutch.
never mind, now i see thats a high pressure, would that switch stop comlpressor from starting?
