Prius (Gen 3) :: AC Blows Hot Air
Jul 26, 2015
Went to turn on the AC on our 2011 Prius and its blowing out nothing but hot air . The AC lights light up as if it's on and operates as if it's on but it feels like the heater .

View 13 RepliesMy low-pressure hose got a hole in it and now my A/C only blows warm air due to the leaked refrigerant. How to remove the hose at the connections as it is not using standard steel hose clamps.
View 6 RepliesI have a Buick park avenue 1998, 3.8L V6 engine. the problem is: The ac vent on the driver's side blows cold air but on the passenger side blows EXTREMELY hot air. no matter how cold or hot you set the ac it blows at the same temperature on both sides. Florida heat is setting in and my passengers are melting. I am really hopping that is not something to bad and that I can fix it myself. Tip: this started happening after i had the alternator and the battery replaced.
View 1 RepliesMy Prius air condition blows hot air sometimes, sometimes it works fine, warm weather seems to increase the problem. Took it to the dealer, they couldn't duplicate problem, said it was fine, but it is obviously not. Where should I start, don't like the replace parts till we figure it out thing. Don't think its the compressor b/c sometimes it works, sometimes it doesn't. Fan is working fine.

Sure seems like a voltage regulator-type issue. Is it possible that a single wiring harness can affect both left and right? It's strange, because if the left one blows today, the right one will blow within a day or two. I've tried every brand of bulb, and no, I do not touch the glass with my hands.
View 19 RepliesI bought my prius IV brand new in December, and its my first one. One thing i've noticed that's different, but when I have my AC on auto (I've preferred using Auto since my last car..) I notice when its cold out, it only blows to my feet, then eventually maybe after driving for about 45 minutes or so it will eventually switch to feet and air. Is this normal? Why it goes to just feet only for so long?
View 2 RepliesI have a 2004 Gen II that blows the A/C(Htr) 10 amp fuse. The dealer changed the inverter and replaced the fuse with a 15 amps which masked the problem. I have looked at the items that this feeds and have eliminated the: inverter (Dealer knows very little, Scary), A/C Control assembly, heater water pump assembly. I thought that since the Heater water pump assembly runs intermittently it might be that. Or could it be the diode in the relay that controls it? I cannot seem to find where it is located..

View 4 RepliesMy 2007 Prius air conditioner blows mainly warm rather than cool air. I took it in for repairs and they replaced the high pressure hose but it is still not cooling the car. The dealer has had the car for 2 weeks trying to determine what the problem is. They tell me it should be blowing 42 degrees but is only blowing 62 degrees. They think that it might be the invertor that cost $1,000.
View 1 RepliesInverter coolant runs low and also regular coolant blows up. Do they use one line together? Everyday I have to fill the inverter.
View 4 RepliesI tried to use my A/C yesterday and all I got was hot air. I've only had the car (06) since the end of January.
View 5 RepliesI made another thread about when I turn the AC on, it blows hot for a few minutes, sometimes almost 10. I decided to go get a recharge kit and when I plug it in, the PSI is almost 60-65. It should be around 35-40. Is this normal for these cars?
View 4 RepliesI installed an Old Air products aftermarket air only AC unit in my 71 F-100 and this unit has run perfect for 14 years until this afternoon. I ran the AC on the way to work, cold as usual, and when I left work it will only blow hot air. The clutch is working with the fan switch, the fan is working at all speeds, the compressor is turning and the fuses are all good. What happened?
View 2 RepliesEvery thing was perfect till suddenly my A/C blows hot air on hot summer days when it over 104 , everything works motor clutch , fans so when its hot outside the motor & clutch turns on & off and wont cool it all started when I refilled my AC, I might of over charge a little. Not sure how to fix.
View 1 RepliesI can't figure this one out. Sometimes I turn it on all the way and it blows very little, barely noticeable and then it comes on eventually. Sometimes it works fine. Sometimes it seems to come on if I hit a bump or something and then off.
View 14 RepliesAs the weather here on the east coast is starting to warm I decided to run the A/C. Well low and behold it blows warm air, regardless of what I do. I put it to LO, nothing. I made sure to turn ECON off, nothing, I even tried to cycle the ECON button but it doesn't seem like the compressor is being turned on.
Will be calling the dealer tomorrow, it is well within warranty. Just sucks I have to deal with this, plus I see that there is a TSB out but it only lists codes as to why the compressor, if that is the problem, is not on.
What was done to resolve? The A/C last summer worked fabulously??? So I hope it is not a coolant leak or something like that, hope it is just a faulty sensor or switch.
On start up, on the hot day, A/C takes 4-5 minutes of driving before starting to cool. Not much cold air coming out once it get's going to.... IF Climatronic is switched OFF, then as you drive you can feel hot air coming out from vents and actually fogging up windscreen on the rainy day.
View 8 RepliesI got a SFS 2.0 Turbo 2014 about 20 days ago. The car is back with black interior and navigation package.
Since day 1 I had noticed that the fan always blows hot air, no matter what the outside temperature is. Air conditioner cools the car sufficiently, but low temperature setting on the thermostat is needed.I feel the fan is pulling hot air from the engine compartment.
I am due for a service in about 30 days.
So last summer I had the AC recharged. Worked great. I only ran the AC about twice over the winter to lub the seals (about 30 sec) prob not long enough but anyway.
I used the AC this month a couple of times briefly and it seemed to work just as well but today I get NOTHING except hot air. I cleaned the cabin filter, it sounds like the compressor comes on cause I know it makes that kick sound a few secs after hitting the AC button which illuminates. I took a quick look around but didn't see any leaks. fuse looked ok. I noticed the Low pressure line is wrapped.. do i have to take that off to check for leaks?
Does this sound like the refrigerant is low again after only like 6 months. If it worked great last week now nothing does that seem like the issue? Thinking of just filling up from autozone myself. I've also have a bad BCM with intermittent light/dash/window issues which arises in heat for past 2 years.
When I start my passat, it blows cold air after a couple minutes as it should. I'll start driving and the air continues to blow ice cold air as it has for years BUT as soon as I stop in a parking lot for a couple minutes or park in a driveway and the car is not in motion, the air blows warm dead air and stays that muggy way until I drive again which then it'll be ice cold again.
View 10 RepliesI have a dual zone climatronic in my 04, I just noticed it last night that regardless of what temperature setting the passenger side is in, it just blows cold air. Winter is fast approaching.
