Friend of mine she bought a 96 Suburban K2500 3/4 ton she has been driving it around for 3 years with no AC all because of this. I found the 50 amp blower fan fuse was burned out. I replaced it fan works now but AC compressor doesn't turn on relay is good. We noticed the lights don't turn on just like you described in the video for recirc, and AC. We got replacement for $142 on amazon and fixed it. Thanks for making this video.
I have watched tons of your videos to help with my 95 C2500. I seem to always end up finding my way back to your channel when looking for a videos to a 95 specific problem. Every time I thought I had seen all of your videos and then one comes in to save the day that I hadn’t seen before.
Thanks for the video. I always thought 95 had a one off AC control that you couldn’t replace with newer.
I need the one for 1995, I was told the wiring harness is different. Do you have a solution?
Thank you thank you thank you Jimmy!!! You cannot imagine how you help us here!! I’ve bought a 1997 Silverado, thanks to you I’m putting her in perfect shape!!
I am doing the same with my 2000 c3500.
I did mine today -GMC 1995 suburban. Now my rear fan; A/C works & air recirc button.🤙
Hello again 1 Road. I had similar issue with my 95 Chevy Suburban. Did the same as you and now it works like a dream, thanks for the video as it kept me from pulling my hair out. Great video once angain, thank you for sharing! Keep up the keep up.
New does not work .only has high speed.the old one was doing the same thing.can you help.
@@johngarza1638 Sounds like a blower motor resistor problem.
Very well done video and super helpful. Thank you.
Thanks for taking the time to post. Good stuff - going after it tomorrow!
I drive a 1996.. after obd2 I am assuming it is the so called improved one. I swapped to LED (t5) lights near 350k miles and 23 years old.. just for something fun to do. Never failed, always works perfect. I mention lights, as heat will kill any electric. LED coolsit down, drops the amp usage to 8 times less. the door buzzer was so annoying to me, I swapped it for a 99 camaro...plugs right in.
The door buzzer is easily removed and plugged back in, just fyi. Thanks for sharing. Good job.
There's a reason most repair instructions say to disconnect the battery before starting repairs.
JavaMan lol, he said that because the buzzer was going while we was talking. There’s absolutely no reason to disconnect the battery to remove/install a door buzzer or even a fuse.
in my 99 yukon I had problems with the blower motor switch. like the speed wasn't what I put it on. so high was like low etc.
I’ve had this problem since I put a sound system in my truck back in 04 and just started driving my truck again now I’m redoing my truck because they are super great and reliable trucks
This happened to me as well. I put in a new stereo and about 3 hours later the AC control stopped working. Do you know why this would be?
thank you soooo much I went to replace mine (95 Tahoe) for the same issue but seen the design of the rear was different from the 95 to 96+ so I thought it was a 1 year only now I can just upgrade to new design. Love your channel
Got a 99 Denali today on the way back home the air had stopped blowing completely and the ac button and circulation button don't light up no more. I'm guessing replacing this and the blower motor? Hope it works and rear vents just shoot cold air no heat
I am missing a knob on my rear control panel and I have a replacement knob but when I put the new one on it can be effortlessly pulled off. I cannot figure out why
i bought new heater and AC controls like you said. it didn't come with wire harness adaptor!!! i had to get one from a junk yard> because they do not exsist on ebay or amozon!!
Only one harness plug fit , on mine do I need an adapter for the the other one ? It looks like the new one in this video . I have a 95 GMC Sierra.
I have a 97 silverado. A.c. now only blows on high. If switched to low or any other speed it will not blow. Placimg back at high I have to give it a few turns and sort of ding on it to miraculously make it work back on high. I will clean out blower motor and make sure it is working or any clog is cleared out. From your knowledge please help me and let me know what my issue might be. It could be what you replaced..maybe worn out knobs..who knows.
Thanks in advance for the help.🙏
Nice video thanks
My unit wasnt turnon on my ac. Button for ac didnt light up. Put in a Dorman unit. AC button lights up but my ac clutch wont engage. Tried jumpering low pressure switch, same results. Tried direct power to the compressor from the relay center and it works. Not sure what it can be.
I wonder if they have a unit for a 2003 Silverado great video
Mine is doing this and blower can be operated even with ignition switch in the off position. I am looking for a power source some how getting to controls with ignition off.
Do you know where I can get a rear climate control panel? I am missing the knob to choose between hot and cold
Great video but im having problem finding this product with pig tails like the one in your video, could you supply part number and manufacture many thanks keep it up
@1road does it work on a 96 model,it's the same model as yours just younger
Did u have an issue with the new unit not blowing as hot as the old unit? There is a 30 degree difference between the old and new. I used a 96 unit with a wiring adapter though. I noticed yours does not have the wiring adapter.
Do you have that link to purchase H back climate control unit for my 95 Chevy Tahoe?
Mine doesn’t have a rear window defroster so the one I bought didn’t come with wires, does anyone know how I can plug it in
Thanks for the video. I need this part for my 95 Chevy k 1500 pickup without rear defrost. I followed your link but they are sold out with no restock date. Do you have any other sources. Thank you.
do you know where the harness goes connected that's goes into the back ?
does a 2000 youkon ac control panel exchange with a 1998 or 1999 yukon please need help
anyone know where i could get the ac controls module harness ?
Yeah, i used the pc board part number not the delco number and got the oem part for $60. Some people advertise NOS for $700. The reason why there are issues is because the rheostats are worn or gummed up. No way around it with humidity and dirt. The new and improved version makes a weird noise.
Can you buy a separate wiring harness to mate up with the controls in a 1995 GMC Yukon? There are six prongs to connect to and the device only has two connections
Stefanie I am looking for the harness adapter as well did you find one and if so where at? Thanks
I've got a 1999 gmc suburban where my high doesn't work. Would this ac unit work?
It's the "dash bezel", not front fascia, that's on your house. Doubt the problem is in the fan switch, more likely in the air direction control or a air door servo which is not part of that panel.
On Chevy's and really, any vehicle, do yourself a favor and turn these kinds of control knobs slowly......unless tearing apart your dash sounds like fun.
That one fan speed switch itself is serviceable only like 15 bucks online.
Where???
What’s that little screen you have next to the pocket on the dash?
Dam ya bought em all already , need one
Excellent. My.99' only works on high.
Mine does to.what can we do.
I ordered a control module but it’s for a 96 and up is there a adapter wire harness I can order?
Great I was looking for one .dis not know about new unit
yes I did that. it don.t come with wiring harness adaptor> I call amazon and i sent it back they give me a new one still with no wire harness adaptor!! how to fix that problem that no one knos?
What's the part number for this piece on Amazon, it's not in this CZcams vid, any where,thanks
Kevin.
it made by Standerd HS505
We're did you get the connections for the new one I can't find it nowhere
Would this work on a k1500 without the window defroster?
bought my 95 silverado back in december..Beautiful condition only thing is cant get controls for a 95 anymore..
You have to buy one for a 96 and up and the adapter wired to make it work. Not showing it or mentioned it in video ebay for adapter wires the only way to make it work.
@@ronbolton7597And now the oem 96 and up are also hard to find (without ebay markups and cheap aftermarkets)
Been trying to find one, but they want to charge so much for these units. Any suggestions??
Good morning can you tell me the price in dollars of this control in uSA thanks?
My 98 GMC Yukon already has one of the "New" panels [based on how compact it is compared to the old].
One of the issues of late is that the fan control dial sometimes works and sometimes doesn't. I removed the control panel and upon inspection noticed that the brown wire port on the harness leading to the fan control was deformed/melted.
After cleaning it well enough to test the connection and make sure it wasn't shorting, I turned the fan on to med-low [two clicks clockwise] which did work now, and noticed the fan control harness and wiring was getting quite warm. Not to the point of being unsafe or too hot to touch, but I only ran it for perhaps 60-90 seconds.
I'm curious if this issue is unique to me or not. I'll leave my last observation that the wiring gauge does not appear thinner than the wiring on your new control unit- they appear rather identical, at least as far as I can tell.
For now, I intend to replace the wiring on the fan control harness and perhaps the harness itself.
I have a 1997 Yukon, and I have seen several sources saying the AC compressor will switch off and on in any weather by design. I'm not sure what it accomplishes but that is what I have read. So... the control unit could working as intended.
They run when the defroster is on to in order to dehumidify.
Exactly right AC always runs in any kind of defrost mode whether it’s combo feet and defrost or strictly defroster. It’s a good thing it helps keep your compressor healthy through the winter season.
do you have an idea where I would be able to find the pigtail plugins for the back of the unit? bought mine off of eBay. and didn't come with any
nathan gonzales , I have the same problem.
Hi. Do you know the name of the lamps in the left one in the picture at 5.37.
Hi there wanted to ask mine is 1995 and found it on Amazon but it says there 1996 and up did your 1995 when you bought it
do you still have the old controller?
Not finding it at amazon anymore. Only for 1996 and w/o harness
question?? heater in 2000 tahoe has been working good, until this morning it just started blowing cold air?? Can you help??Thanks
check coolant level
Currently out of stock. I made the mistake of buying a used one on eBay. All I did was replace my problem with someone else’s problem. There’s another video where I guess some guy diagnosed his and it’s just weak circuitry.
How do you tdisable auto door locks?
we have the same situtation, old model and new one but our new one didnt come with any wires? I can't find them online anywhere, help!!!
Emily Ryland good luck I'm having to fabricate my own wiring and connectors for the one I got. Like tying your shoes when you got wiring diagrams tho
Perfect video thank you for the help. I’ve watched a lot of your videos. I also have a 95 gmc suburban
will that work with a 95 Chevy Cheyenne 3500HD ??
Sucks they dnt sell the panel with the entire harness anymore! I csnt find it anywhere
The 95 is a 1 year specific for that unit and isn't easily found, is that true
Amazon has stopped selling the ACDelco units and just cheap Chinese ones remain. So hard to find a new ACDelco unit anymore. Luckily I was able to buy the very last one on a website that labeled it as only 1 left. But I had to fork over $150. I’m sure 7 years ago when this video was filmed they were much cheaper as you said they were cheap on Amazon. Not sure if ACDelco just stopped making new ones anymore or if they just don’t make anywhere near as many. If anyone has any answers please let me know.
Doesn't RockAuto have it? I rarely ever buy from Amazon.
Where can I get the adapter wires
hi im having my compressor coming on & off aswell,only my rear ac works & not the front what can cause that issues?it has enough freon,plz help
+tino8080 sounds like a faulty control panel. Can you play with the knob and get it to turn on? If so, you may just need a new control panel like me...
1 Road ..thx for replying ive moved knob & still nothing,will low freon cause front side not to blow cold air,rear is super cold tho
UPDATE: end up being low on freon the gauge on can wasnt accurate,& i had just purchased it
+tino8080 I don't think your problem is low freon because the back is cold. That's weird. Have you removed the blower fan under the dash to check for obstruction?
1 Road I bet you they accidentally fixed it when adding freon and didn't realize it lol, cause why wouldn't they have a safety compressor shut off switch that worked for both ac ducts in case of low freon since they run off the same compressor, condenser, lines ect
Thanks!
thank you !!
i have another issue,when i have the a/c off i can hear the clutch on even though ac is off ,the ac button is off too,do you think it might be something electrical with compressor or control panel?
+tino8080 check the a/c & circulate button lights in the control panel... Are they flickering or still "lit" when the compressor is on or the fan speed knob is turned from on and off? Sounds to me like a control panel issue.
1 Road yes light om button would stay on before but it stopped ,now button lights turn off
It appears that this part is no longer manufactured but I keep hearing about a harness adapter to make a 95 model work with the 96-99 models. If anyone knows where to find that harness or this part for a reasonable price let me know please.
Did you ever find one. I have been looking everywhere?
I have the diagram. Message me here or find me on the FB and I’ll send you the diagram. Nicholas Ibarra
@@nicknick9081 i have a 95..I can't find the wiring harness any where..any clues would be appreciated..thanks
@@nicknick9081 Can you send me the diagram please. I might have found it on one of the forums but would like to compare them.
@@nicknick9081 Can you send me the diagram please. Thank you.
Does anyone know where to get a wiring adapter for this to be able to use in a 95 chevy suburban. You can find the main HVAC climate control by itself. Unfortunately it seems most dont come with that wiring adapter if you do not have the special wiring adapter it wont work in a 95 only 96-99. Also AC Delco had completely discontinued the part....
Allec Anderson I have the same issue! I purchased the new control unit, but have no way to hook it up now...😡. Did you find any answers to this question? HELP PLEASE! Lol... thank you
Dan Kelly, No unfortunately not. I've basically just resorted to looking through junkyards in my area hoping to find a 95 chevy that they'll let me get one out off :/ it's been quite frustrating.
Cannot find the Part where can I find it
does that say only 50K miles
Hey 1 road i replaced my controls because only the front vents were blowing thru. Now with the new controls in place, im still having rhe same issue. No air on floor nor dash just front vents. Any suggestions would be appreciated thx!
+Jesus Perez III you might want to check the small motors under the dash that control the flaps that close off and open air flow... Sometimes those malfunction.
1 Road ill check it out and hopefully find the problem. Thank you for replying ,your video was very helpful!
1 Road what did you result with
1 Road for your specific symptoms
Where can I find a 1995 control panel I’ve looked everywhere?
They're hard to find because the transmission & the ac control module are a "stand alone" year I lucked up & found one on ebay around 150.00
GM AC and heater controls are terrible. One of the reasons I got rid of my 04 Silverado (Among many other issues with
Hey Jimmy thanks for the video. Quick question I'm definitely having the same problem but while I'm on the freeway I'm hearing a flapping noise sounds like the door from the circulating button is not fully closed and is flapping open & shut. by any chance did you get any of those noises?
Hey, sorry I've not had those sounds. Hopefully I won't as that sounds like it'd be hard to fix. Man I hate when there's annoying sounds while I drive...
There are several of those door actuator modules. I hear it is common for them to go bad. Try to find those videos. Not sure if that's the problem you're describing. Good luck.
Yeah it was definitely the actuator it just kept running without opening and closing the doors. easy simple fixes just disconnect it that's what it kept the door closed which I'd prefer anyways
It`s your on/off fan switch speed controller real cheap a few dollars at autozone. Don`t spend 150.oo on a new panel I replaced my about every 9 months
So my new switch does not work.
ac not blowing out of front vents but blowing on top of dashboard how can I fix?
Follow diagnostics procedures, find out what's keeping it stuck in defrost position. Is it electrical or is on the doors or motors to change air direction
I need that grey harness! No one has it for my older 95 unit...
I'm looking for one myself...
CGone DFishing that's because the 1995 is a stand alone year for the transmission & the AC control module I lucked up found one on ebay around 150.00 some places sale them ridiculously higher bcz they're hard to find.......
@@sasteveneadams so crazy, must look in to rebuilding my recent one I found,. Seems either the A/C going out is forcing it to stay on after it is 8n off or something else has gone wrong with the switch(s)… 🤦♂️🙃
@@cgonedfishing Check eBay might get lucky I've even Googled shops that repair them! hope that this helps! I just installed my ac control module today because the old one only worked on some of the settings and not all. Everything worked with new module except AC the compressor not coming on so I'll check relays & wiring @ the compressor 2mrw!
Will that fit a 1999 chevy tahoe?
no
i bought one from amazon. but it didn't have the wiring harness adapter for it. different plug design. where can i find wire harness adapter?
my AC don't work on my old heater control. but all i can find is the newer type you show on video. but i have different plug design. i still looking for plug adapter?
i find newer heater control with wire harness adapter on ebay for about $789. it only think i can find!
the one i buy on amazon don't have wire harness adapter.
does the uppgrade allow the reculator buttion to stay pushed in my 95 with stock one if its turned off not on a fan speed it wont click in
The button clicks in but the light won't turn on (recirculate doesn't work) unless the system is running. I'm kinda disappointed because I was hoping to be able to shut those outside vents. While driving, I get too much air coming through the truck...
1 Road I have the same problem with that recirculation button, I'm confused now whether the recirculation remains ON while the bliwer is OFF or not. I live in a very hot climate area and almost never use fresh air. have you tried opening the okd unit and clean the contacts of blower knob? when I wiggle it the recirculation turns ON with fan OFF.
BuDavid I too am learning of this con in a truck of pros, find the yellow wire is the one which is on mine but the 12v wire from recirculation button to the recirculation air door actuator and run a toggle switch to it
Leave orginal wire hooked in to control board and motor, just tap into it and ground your new toggle switch out. If power wire is disconnected entirely to the circulate switch half of the switches are inoperative. Maybe new updated ones aren't on a loop board but the old one I have is
Also inspect loaded buddy springs x2 or whatever they're called to be in between the air door motor (lower driver side of core/duct housing) and goes vertically up in a V system to the upper blend door hinge rods. When ac is off it won't trigger outside air door to shut, the switch has a function to be used whether fan is on or off. Try holding the switch down for five seconds as well with key on engine running and all ac switches off.
My 95 z71 don't have rear defrost
The ones on Amazon say for 96 to 99 is the 95 not the same style?
Nope, completely different.
That's why you must first disconnect the negative side of the battery before removing the panel.
Anyone know where i can buy new chevy parts! i have a 1995 Chevy C1500 P/U and im having trouble finding a lot of the old interior trim/door panels.!
+Bryan Andrade I would try junk yards first.
1 Road What's that little digital display next to your shifter? My 95 k1500 silverado doesn't have that.
Farmin' with Chevy Trucks it was just a crappy aftermarket CD player system and that was the display for it. It's now gone. 😀
Bryan Andrade Lmc trucks great place for oem and aftermarket

This is good music system for Chevrolet suburban
its not on amazon anymore
link says the switch panel is 499 us dollars
For some reason, I can't PM you from my phone or maybe CZcams got rid of PM's without me knowing. I have a 1995 Chevrolet K1500 Suburban LS 5.7L. I REALLY like your videos so far and I'm having many of the same issues. I just purchased and received the A/C control panel today from Amazon, after watching your vid. I truly thought that it was an under the hood issue. I purchased this as a toy and have done a lot of work, including a 6" Bilstein lift and 35's. I'm interested in bouncing some ideas off of you. Anyway, please let me know if there is another way to contact you. Thanks.
+Patriot4TheTree I'm not quite sure how to do that either... Yes, I'd love to bounce some stuff off you too! One thing that's bugging the heck out of me with my rig is this ticking noise coming from the motor. It follows the rpm's and load on the motor so I'm pretty sure it's a mechanical thing. I've done some googling and seem to have come up with a pushrod adjustment. I've even seen some vids on CZcams showing people making this adjustment while the motor is running with valve cover off. I've only got 53k original miles on this thing so I don't think it's anything detrimental. Do you know anything about this sort of issue?
Glad to hear you bought the a/c control panel. Mine is working like a champ. The only thing it didn't fix is the outside air blowing in through the foot vent while driving and everything is off. I had this same issue with my '96 Sierra and eventually manually shut the door that allowed outside air in. Is this a stock setting or is there an issue there?
Talk soon...
+1 Road I haven't had an issue with ticking and mine has 135k on the original motor. The only noise I'm currently hearing is a gravelly rattle at an idle, but I think I need to tighten my header bolts. The manifold use to make a much worse noise.
As far as the air dam, I'm not sure about that either. I do have the same problem but I was hoping that this control panel would fix that. I did notice on Amazon, that an actuator was commonly sold with the control panel. I wonder if that is necessary as well, to close that dam.
I had cooling issues for a while, and eventually changed the radiator out for a Spectre and put an Edelbrock water pump in.
I also changed the air filter. I took all of that big plastic crap out (which freed up a lot of room, which is cool because I will eventually put another battery in there), and now have one of those old school K&N stack style filters.
Your interior door handles and locks will go up on you, if they haven't already. I had the two front handles actually snap off. I've replaced all of mine, but they are a fairly easy fix. I didn't reapply rivets though.
I'm in the northeast and my largest issue by far, has been combating rust underneath. I've replaced all of the brake lines, and the fuel filter being rusted solid to the front and rear lines, has caused me to purchase but not yet replace an entire fuel delivery system including the tank up to the throttle body. I also have less torque off of a stop like you mentioned in your tune up video, and I'm hoping that getting this original fuel filter off will help that.
The awesome thing about this truck, even though I purchased it with the expectation of sinking money into it, is that parts for this thing are cheap. Even upgraded parts are cheap.
+Patriot4TheTree Totally agree about the cheap parts!! I'm curious about that actuator now. Yes, I've had a door handle snap off on my previous '96 Sierra. I bought a cheap rivet gun and did do the rivets... I was wanting to swap out the massive metal and plastic intake bit i'm such a 'stock-look' guy. I'd have to replace it all with something very stock looking. I do like the look of the K&N cold air intakes though.
Here's a question, at freeway speeds I'm getting a vibration that seems pretty much like an out of balance wheel but what's weird is it'll be there for about 15 mins then just go away for a little bit then come back. I'm trying not to think too deeply into and am pretty certain it's just a rebalancing issue. Any thoughts? When I recently changed out my front pads and rotors I tried moving each if the wheels around to check for play but they seemed tight as a drum... Peace bro
1 Road check the u-joints in drive shaft.
Thanks bro, I have a 99 burban Ordering one immediately.
Hey, have to say, since this video was published, my 'new' unit is already malfunctioning. Not to say they all will. But mine has. Basically, in the off position it tends to kick on and off repeatedly. I then have to fiddle with the knob to get it to stop doing that. It still works and functions as normal when in use but... just annoying based off how much these cost. 👍👍
Never except that. I would return it asap!
@@odog4show well, I've had it for quite a while now. No warranty left. I'll just have to try to fix or replace. But hey, at least I'll be able to film it!!
1ROAD try changing your ac/blower switch mine did exactly what your talking about but it ended up going out for good, took it all out and the switch melted my wires so I changed my wires and bought a new switch never had a problem since!
My 95 Yukon Ac wasn’t working due to a relay once I replaced the relay it worked a few weeks now when I have the blower control off the Ac Compressor will turn off and on with the push of a button but when I switch the blower on the Ac Compressor will not engage whether or not the AC is switched on or off. I checked the fuses and relay both good I’m confused I’m beginning to think it’s the controls because it turns on and off with the blower off also I can’t get it to switch vents with the controls
TacoEating SoCalgrower check the electrical connection behind the blower switch mine melted out 3 times before I found out that my blower control switch was broken and wouldn’t turn off, changed the blower switch for 30$ never had a problem since!
@@zachdowns5927 do you mean the blower motor???
My compressor doesn’t come on ..I gave it direct power and it worked fine ..what can it be??
John Doe how do you give it direct power? Same issue here
Its probably the control side of the circuit, check relay while your at it
John Doe
Could be low on refrigerant (Freon), or low pressure switch on the dryer: the canister looking thing on the firewall.
And ac performance control for Chevrolet suburban silverado
Those exposed circuits should be protected by something. IMHO.
Air bags in newer trucks add to the cash removal drama
I had this same issue everyone thinks i was crazy
Disconnect you negative on your battery.
JERRET CARRIERE that don’t need to be done unless service the SRS system.
AH HA,im glad i saw this my bulbs are all out so i wanted to swops with blue Led's like everyone is doing,well mine if you look at the one you took out,each bulb has a yellow and black wire going to the one piece bulb that doesn't look like you can change them,i know they can't be swopped to Led's,look at the back of your new one,it is capable of swopping to Led's,so damn it to change bulbs i need to buy the whole new unit.thanks for the video.now i need to shop.
No longer in stock ...can anyone help?
Here's Why You Should NEVER BUY BRAND NEW PARTS AGAIN!!
Sorry, tried to post a link to one of my latest videos... I actually repair the failing knob on my ‘new’ air conditioning control module... go to my channel and search this title: Here's Why You Should NEVER BUY BRAND NEW PARTS AGAIN!!
