My fan runs. Works perfect while driving. Sitting still... blows hot. 2008 honda CRV

Thank you so much! I had the same issue and you saved me and my family a couple of hundred dollars to take it to someone only to tell us it is the fan, something I ended up replacing myself. I do most of the work on my truck myself but stop short at electrical (other than fuses and battery issues) and AC issues (other than recharging). Thanks again!

The evaporator would not cause cooling to stop at idle. If the evaporator is leaking it could cause low refrigerant. Low Freon would cause the air conditioning not to cool regardless, if the car is at a stop or going down the road. If driving down the road helps it cool, it's most likely the cooling/condenser fan by the radiator. The air blowing across the condenser while driving takes the place of airflow that the fan would provide. But it's a good to look at the whole system incl. readings

Ok here's one, my 01 F350 7.3L, doesn't do it all the time. So far I've cleaned the condenser and the fans work. It blows ice cold when it does work. I live in the south around the New Orleans area, on really hot days It cuts out sometimes at lower speeds, say 0-40 mph. If I turn it off for a few minutes then back on sometimes it comes works again. It always works at highway speeds. This ones got me confused for sure. Thanks for the video. Best Wishes n Blessings.

You didn’t cover vehicles that don’t have electric fans. Such as the typical truck with a fan run off the motor through a fan clutch.

Is it possible to need to replace the condenser of 2011 Kia Optima if the ac is blowing warm when the car stops or in traffic?

Sir please give me a solution on this , my car is ELENTRA 2015 model ,my a/c stops working in ideal , and works perfectly alright when crossing 70kmph ,some times it's working even in slow speeds....but not always on slow

Have a 2011 optima 2.0T, A/C works when been driving a little, if in stop and go traffic or at idle it stops cooling. Soon as I turn a/c on the electric fan works, so isn't condenser fan. Also checked the low pressure side and was in full zone. If car sits until cold, the a/c does come on at idle until engine gets warm. Any ideas?

My 2009 Subaru blows warm when idle, but fans seem to be fine, because radiator temp doesn't go up, even at traffic jam. A while back the compressor was replaced, the rest is OEM.

It’s the fan clutch or the cooling fan

I have a 2003 Pontiac Sunfire. I have replaced the condenser, condenser fan motor, and radiator. Also had the water pump and thermostat replaced as well. I had my ac system evacuated and recharged. It is still blowing warm air when I am stopped or idle and then gets very cold when I am driving (usually 45-55mph) Anything under that speed will not work. I replaced the dryer/accumulator, orifice tube, and ac lines. Only parts of the ac I have not replaced is the compressor and evaporator (inside the dash). I am completely lost as what is happening. I did notice that the car is also running around 3-5 degrees hotter. Before, my car would run at 195 and maybe 196-197 when stopped. It is now getting up to 199-201 when I sit still. The fan engages but the ac will never start blowing cold again until I get back on the freeway doing above 45mph.

I have a 2010 Nissan Armada. When im idling my air blows real warm. Then when i drive it takes a bit but eventually blows cooler. I checked the condenser fan and it was blowing. Im not sure what the problem could be. Any suggestions?

When I rev the car at idle the AC comes on. When the rpms drop below about 1,500rpm the AC shuts off again. Works fine while driving as well, only as long as my rpms are up. Any idea on what this might be?

What if your vehicle does not have a condenser fan and sits in front of the radiator. Cold while driving not cold while idle. Could I ad universal condenser fan or would you just replace the condenser ?

My car's AC stops working when going uphill on a hot day. Any ideas?

I have a 98 Lumina LTZ that has a problem with the blower/vent system, and I'm hoping you can help. The air blows fine out of the dash vents when the car is idle or cruising but not under heavy load; when accelerating or hill climbing the air stops blowing out of the dash vents altogether. I want to say it starts blowing out other vents, but I haven't really had a chance to test that theory yet. What could cause this?

I don't think the evaporator has anything to do with it since I got mine replaced recently. I'll be sure to check the fan to see if it's blowing in the right direction since getting the wires wrong seems to be a very common mistake by hackjob mechanics. I'm reading about how to read the gauges so that I'll not be totally clueless when I bring it to the shop. Thanks for the video. It was very informative.

What does it mean when I turn my ac on and the idle goes down then up. Sounds like it wants to stall at times. 2001 ford focus zx3

Ok let's say condenser fans are not properly working and gas refrigerant isn't being converted back into liquid. Would it cause an over accumulation on the high side gauge so maybe a spike in 25 -50psi?

In need of your advice, im driving a honda city 2012 model, My ac doesnt blow cold at idle , i already checked the fan and its working but doesnt blow cold at idle..what should i do?

Help. I just recently replaced a new car compressor. my car ac blows only air when idle. but blows cold air when driving in highway at certain speed. i checked that condenser fan operating fine. and have already recharged freon. what seems to be the cause of problem?

My 2012 Kia Optima has this issue... Been to 3 different dealerships and they said its "fine", I also had relays replaced because sometimes the fan won't come on at all. On the first day the relays seemed to fix it, air blew cold all day. But then a few days later I noticed it being hot again at idle. It only does this on hot days usually. I noticed that my fan is really quiet unlike most cars, could it be that the fan isn't moving fast enough? I could really use some advice from anyone, thanks.

I have the same issue at idle. Fans are working properly. Also I noticed when the fans kick on the freon level drops, is that normal?

im having same problem in a 07 grand marquis . A/C is fine then when i come to a stop i hear a click noise the engine idles down a few hundred RPM and then the A/C is hot till i take off again ..Can you help me ??

My ac works for awhile and than I hear a pop and it starts to blow hot air, so I turn off wait a bit turn on it works than after it pops again than hot air. Replace the relay still have same problem any suggestions? Thanks

i need your help, my wife's car 2007 ford focus ac blows cold and then out of nowhere it blows just warm then cold again.. its been doing that for a little over a month and its getting annoying.. what do you think the problem is?

What about a clutch fan system?

thank you for you prompt response, I live in ontario California, not Canada,

pls help. i have a problem my ac doesnt work when i stop or in idle, but wen i turn on my rear ac it blows cold,do u have anay idea why? thank you

2006 chevy hhr ac works perfectly fine when its not that hot outside.... it shuts off when its too hot outside it only has one fan i see that it blows way to little the air condenser has a dent on it idk if should change it out.... one time it smelled like vinegar through the air vents..... any idea what could it be..

Plz help! I have 2008 GMC Acadia with a/c not blowing Cold. I had a/c recharged but that didn't fix the problem. Doesn't have a freon leak either. Then I went all out and replaced the compressor and condenser but it's STILL not cold. According to mechanic gauges showing what their supposed to so a/c should be working but it's not. $1000 later....He's stumped and I'm frustrated! Any advice would be greatly appreciated.

i have that problem but when in traffic car wants to overheat, once i get going it is fine,

I have an 05 Focus and my AC turns off after 15 minutes, I thought it needed a recharge but when I put the Gage it went to the red past 100 psi. Any ideas of what's going on with my AC? Thanks😀

Can anyone help me, 08 civic ex compressor and clutch are running, pressure is good, plenty of AC liquid, only blows cold air when i press the gas pedal but when i stop it blows regular air not cold not hot but regular! Anyone know what can be causing the problem ?

I have an 03 GMC Yukon that doesn't have an electric fan and has the fan on the water pump pulley when I'm driving very slow or come to a stop the air conditioner starts not working as well as it does when I'm driving I've already cleaned my condenser and everything out butt it's still working the same do you have any idea what I could look at or fix next

Hello. I have a 2006 Volkswagen Golf GLS, The AC is not running correctly at all. It won't blow any air at all sometimes. If I hit a bump in the road it will start running. it's will run on all setting low, med, high, cold, warm and hot. IT works on all areas like the floor board and air vents and defrost. Sometimes it will just stop working and turn on and off. The compressor turns on, it runs the right cold and hot. It just started not running at all when the compressor is on, only the defrost. I replaced my blower motor and my fan 4 years ago with kinda the same issue. IT was never this bad though. what do you think? Thank you for your time!

Oh, thanks for the answer! I'm sure it must be the fan in my car cuz after I had to change the compressor the person who did the repair had the fan mounted at a slightly different point which he said wouldn't be a problem

i have 2001 1.3l Corolla Japanese model. i bought DENSO compressor 4 months ago. im expereiencing less cold air in idle. i opened the front and tested the cold pipes, it gets colder when i rev high. although my idle rev seems to be perfect. why my ac requiring high rev? i experience same issue before i bought this compressor, it got weaker and weaker. i dont want this new one to die to soon. not even 1st season passed. pls help

I haveTaho Z71 model 2003.Its A/C started to cool the back side only and there is no cooling in front side?Any advice would appreciated

Hi, I have A 2001 Subaru Outback and when i was driving about a week ago the air was fine and it started making a "train horn" like sound. After that a few days later the air started to not work as well and would not be cold at stops (red light, stop signs, etc). Currently whenever I turn the air on it makes a very loud screeching sound and sort of like a gurgle.

Is it by chance related to the evaporator that the AC is unable to blow cold air while idling??

what is idle temperature at which car ac vent blows air

Thanks for your reply, the information and video you provided is very helpful thanks very much.

Question, my AC and Heater fan slows down and speeds up from an idle through acceleration. I notice this with the speed of my power windows, power seats, etc. I thought it was the battery strength, so I recently replaced it with a stronger model, but no change. The alternator reading is normal and shows no change from idle through acceleration. What do ya think is possibly causing this? Thanks for any help.

The reverse is the case for my ml 350 4matic. It only cools when its idle. For some reason it stops cooling when I accelerate. Almost as if the compressor just shuts off when I step on the gas!! Any idea what could be causing this??

Hi! i got a question. I have a chevy sonic 2013. Since i bought it the ac have gave me a lot of trouble. The car was ''repaired'' last November after 5 visits to the services center, the thing is that now is doing the same thing all over again. What my problem!? When i start the car, it start trowing cold air but after a minute, it suddenly start trowing warm air, when i hit the throttle and engage the car a 60mph it start blowing cold air again, after 2 o 3 times in this situation, the car keeps the cold blow air all the way... before all this back in October and November.. my car was recharged with freon cuz the car lost it all but they said dint find the leaked area... meaning that there is no leak of freon... never believed this. Things like this have made me think that factory warranty are no good and i know if i pay to a private Repairing AC Shop i could get my car finally fixed. Any thoughts? Thanks!!

hi. my nissan note is a very nice car to use. But lately if the ignition is on, I could notice a heat and a strong heat smell even though I do not turn on the heater, what do you think this problem is, please?

I have the same problem with my nissan pathfinder 06 but it's with the heat it blows only while driving???

I have a 2002 saturn and jst bought a refurbished ac compressor it doesnt cool when its idle and the mechanic said its an energy saving compressor. Is this true or does he not know what hes talking about?

hi, I have a Ford escape 2010 and my a.c. starts, cool and everything then dies down. what do you it might be?

I have a good set of manifold gauges. i can give you the readings if that would help?

Mine works great at speed most of the time and does this when it is idling and sometimes when I'm driving. My condenser fan turns fine. I think it is my tensioner. What do you think?

Thank you, very helpful

I have a 2007 jeep liberty. A.c. does not cool. 75psi on the low side and 250 on high side. I did relieve the pressure down to 40 on the low side. High side dropped to about 175. The a.c. got hot then. Also noticed that the pressure started building up on its own. Low side went to 45 and the high side to 200psi but still the a.c. was hot. Any advice would be appreciated. Thanks

I replaced the condenser and the only fan on the radiator (16") still have this issue

i have the same problem. can you tell me which direction the electric fan should spin on a 03 durango? should it spin clockwise or counter clockwise?

thanks i have same problem blow hot air at idle but fan is working this only happen in extreme warm days

my ac works fine but when im coming to a stop my idle drops to 400 rpm then goes back to normal any ideas?

great video where I can buy the conversion kit for my old r12 Guage to r134, thank you cheers from ontario ca

I have a 2010 Toyota corolla, it blows cold air while driving, and the air remains somewhat cool when I stop but not as cold as it is when I'm driving.

Hi 2008 Ford Focus. I have this same problem but recently replaced the radiator fan. Is this the same thing?

08 dodge nitro stops cooling at idle and it also has a smell of mildew.

I have the opposite issue. I have a 93 Town Car which I love and want to keep it forever. When the car is at idle, the ac works cold as ice, but after when its moving the or if i revv the engine the compressor kicks out. any ideas? perhaps low on refrigerant? Its around 40psi on the low side under idle but when i rev it goes lower and kicks off. Any ideas?

My fan kicks in and goes off and the problem with my A/C it blows warm at idle and cold when driving. Is my fan suppose to be on all the time when A/C is on?

I need help...car ac is cold when idle but when car is running ac blows air only...if I stop again cold air comes what could be the problem.? I'm driving a yaris 2007. thanks

hi and thanks , very helpfull, i have a problem with the fans, they work when a/c is on but at slow speed !,,,,and tha car is not Hi and Lo speed fans , i dont know what it is , when the a/c is off and the car reach temp the fan works at faat speeed ! ,b ut not when a/c is on ,, please help thanks again

You look like al pachino

Hi! i would like to inquire also on a opposite situation. May AC stop cooling when driving on the highway from 40kph above.

The used car market is hot! See my experience selling a car to Carvana! kzfaq.info/get/bejne/Z8qSaNFqlqyrk5c.html

low side 15-20psi high side 50-55psi about 86 degrees out

So what if your car dosen't have a condenser fan?? Another waste of a video that answers nothing.

HI, I was hoping you could help me out. My AC is having a similar problem, instead it blows cool air while idle or driving at low speeds and warm air while driving at high speeds. It usually stops blowing cool air while driving 55-75 MPH. Any Ideas? Thanks in advance.
