Did just as you said and AC worked again! Thanks for saving me $1200 and a major headache!!
Wow nice job!!! Defiantly saved the ac from being replaced !!! Good job!!!
hi thank you for shering your nowlege i have 2014 no power to ac blower work heater work but ac not can you help
Thanks for the heads up, help, we have a 2000 Toyota sienna 6 cylinder. I have a better trouble shooting technique now after watching your Ac video.
Nice!!
Your channel and videos are the best. Saves me time and money...
I have a 2007 Toyota sienna. Freon is full but it blows cold air only when driving but blows ambient/room temperature air when idle. Compressor and fans turn on as normal. Any advice?
I just had that issue on my sienna yesterday and it’s due to low Freon so when ur driving the compressor turns faster and also air flow cools condenser my car has leak small leak in evaporator core so what I do is recharge after 3 months every summer how ever u need to reservice the system it maybe low use ac machine recover vaccum and recharge the system
@@RBTheMechanic thanks. I'll give this a try
2015 sienna, seem to be cold when running on freeway, cool at best on idle or low speed. My friend add more freon but he say low side only go to 60 and high is not high enough? Fan work. Any recommendations?
Well if he used can to fill that’s no good u need to reservice recover it all and vacuum the system to recharge With cans u will never have the correct amount too much will cause as to malfunction to little malfunction
Thank u for sharing knowledge
Welcome!! Anyways I can help is worth it
Hi RB. I have a 2015 Sienna and the AC blows ice cold when at idle or cruising but blows hot when accelerating. Then after about 30 seconds is cold again. Problem occurs when accelerating. Fans are working. Cabin Filter clean. High and low pressures on the gauges are within spec. Had a shop evacuate/dry the system and charge to the correct amount. I also put a new flow sensor on it but the problem still remains. I think it may the compressor control valve, lock sensor, or the compressor itself? Have you seen this issue? Thanks for the awesome content.
Check to see ur pressure reading it could be air pressure I usully get these type of issues or not cold enough and I do reservice just to clear out doubts
Hi RB, thanks for the video! My 2013 sienna AC just not working, when turn it on, thno cold air, car engine is not runing harder as usually it make lauder noise when turn AC on, and also there is no water coming out on the floor. And advise? Should i replace fuse, switch, relay? Or add AC recharge frigerant? Thank you!
Start with checking pressure and relay also check if low side like get cold
I have an 08 sienna do you think the relay could be bad if it blows hot only during idle?
During idle mean low rpm compressor can’t pump enough cubits slow rpm and low Freon so try reservicing ac systym with ac machine recover vaccum and re charge propperly
Hi RB , thanks for your content and very helpful. I have a 2021 sienna and just recharged the AC but does not blow cold and AC turns off every now and then, also rear vents don’t blow high enough at all? Would appreciate any insights on what could be the issue please and thank you.
Dose the ac compressor come on? Dose the Mac line get cold?
I have a 2013 Sienna. From this summer, I noticed my front ac works only when my rear ac is turned on. Any thoughts?
Not sure maybe somthing to do with bled door
Hello RB, i have Toyota Sienna 2018 model and front AC is working fine but Rear AC is not blowing. do you have any idea that do i need to replace blower motor or should try to change relay?
Thanks in advance.
Check rear blend door
Hello i have a 2014 sienna it blowing cool ac but not cold do you think its the relay
No not relay it might be low on Freon or ac compressor is weak so u have to first check low and high pressure reading with ac on low side should be above or at 35psi and high 250-280
However, if the fuse blows? Could be signaling the compressor is failing?
I know that fuse on Taurus & I call it the "compressor's going bad fuse"
It could be or weak fuse or could be too high pressure locking forcing the clutch
@@RBTheMechanic yes. Technically the clutch. I just replace the whole unit but I mean if clutch throws a fuse. Start with fuse, relay, etc. Good call. I got the 2006 sienna, but a friend with an 04 is chasin an ac issue thx
Could it be the relay if my ac works sometimes? My ac works mostly when I'm driving. But when I stop, it blows warm air
No not relay that seems like low Freon it will push more and cool more with high rpm and less when u slow or stop down. By the way check ur fans to see if they work on the radiator that could also cause this type of issue since u will get air cooling from the wind force but most likely u got low Freon might need to reservice the system
@@RBTheMechanic awesome. Thank you!
Nice
Hi! My 2015 sienna have a issue, mormings blow cold, but sometimes just stop the cold and just blow but no cold or hot, just blowing. Sometimes was blowing cold but if turn off the truck and turn on in a few minutes doesnt cold anymore. What do you think?
Start with servicing the ac systym it maybe low on freon
@@RBTheMechaniclike 5 days ago, changed everything. New compressor, condenser, valvs and evaporator clean, everything done by a “professionals”.
Great video, but my sienna is an 06 and doesn’t look anything like this
Similar but diffrent this is 2017 and up
2012 toyota sienna a/c not working when the weather is hot. But when the weather cools down or under shed it work. what could be the problem?
I think ur ac is working but it’s not making cool enough on hot hot or sunny day or in sun. There for I would recommend u to do ac service with ac machine Freon might be low
Ok, thx.
Hi I hope you can help me
2005 sienna the ac is blowing only hot! I check for leaks, Freon and the relay. They told me it is something electrical but nobody can help me
First check Freon pressure low and high side with ac guages and give me the reading
Excellent. Before buying fuses, how are they tested?
U don’t test them just replace the relay and check the fuse if u have test light
@RBTheMechanic Thanks and have a great new year!
@@jaimedpcaus1 thank you Happy New year!!!!
Ok we own a 2012 sienna I added a can of r134 after doing so the compressor stopped working … prior to me adding the can it was working but wasn’t blowing it very cold kinda musky ?? Now it doesn’t blow any cold air out … my wife told me the ac does work at times but than stops blowing cold air …. What could this be ??
It is never good idea to use cans you have to redue ac service. With ac machine recover vacuum and recharge correct amount.
have you fix this mine is doing same thing 2012 sienna
@@dinomusi1982 I took it to a shop and he replaced everything compressor relay switch etc … worked for a bit than just stopped cooling ! This is bull I paid well over a grand me and the wife are thinking of trading it in …
@HermyHerm heybso I got mine fixed it was little flow sensor on a compressor. To test turn the car on and ac on....if ac clutch is not engaged, put little magnet over the flow sensor and see if tha turns it on if it does its that flow sensor you can get it on Amazon $20
When i turn my ac on front of the car is shakes! Changed all mortor mount couse they were broken.and still shakes
Any ideas what it might be
Where did u buy those motor mounts from if eBay they all bad if from autozone they all bad or some bad mostlikely all bad
@@RBTheMechanic i took it to the mechanic i don't know where he order them from
@@viktormora5260 we’ll need to find out cuz I have had bad experiences with after marker parts check my engine mount videos I talk about it and redue engine mounts
Hey, how’s it going? Can I set up a appointment to visit you in Jersey? My AC has a similar issue
Only prepaid appointments
Good morning what is the best way to set up a appointment?
I have a 2005 Sienna. The air works on the driver's side and in the back but passenger side blows warm air.
Possability low Freon or bad compressor start with check pressure readings
Hey where is your workshop ?
I’m in north nj
My compressor works , ac is running but no cold air I had it recharged it worked then stopped and no leaks in the line
Did u check Freon pressure with guages
it was the fuse all along 😂😂
Oh ok good I’m glad u found the fuse
How to diagnose a bad AC relay? 😢
No dignostic replace it swap test it
are u in Tampa
I wish!! I’m in north nj
@@RBTheMechanic what town in north nj? great video!
