So, I get in my car yesterday after being away for the weekend (the car has been sitting for 4 days). I get in and crank the AC and it blows warm air. My first thought was "here we go, I need a new AC compressor". I decided to pull into a driveway and I turned off the car, and then turned it on again. When I restarted the car, the AC kicked in like it is supposed to. Cold air as always. Is this a sign of the AC going out?
View 4 RepliesI know last year it was working fine, actually went pretty cold. Yesterday it was 93 degree here in Wisconsin, so thats pretty hot for us. Anyways, It's blowing warm air out, not hot or anything just pretty much outside air (the feel of it atleast) Can this be recharged with free0on or w.e it takes??
View 2 RepliesIf my car get really hot, it initially blows cold air (the way it should be) for 5-10 minutes, but then it slowly starts blowing warm air until I get the full heater going for about a minute, and then it goes back to cold air, sometimes after 45 minutes the cycle repeats. This does not happen every time, this year I had it happen about 5 times.

My call didn't start two days ago, turned out to b dead battery. Got it replaced at local euro shop but now AC is blowing warm air. Called the shop they say, they didn't touch any wiring related to AC.
*could there be anything they forgot to hook back up that's causing this?
* any fuses I can check?
* do our cars need AC recharge?
I've recently purchased a 2007 Prius and I just noticed few days go that A/C blows warm air (weather was fair when I bought it and I can't remember if it really worked or not then) and middle vents do not blow any air. I'm not sure if two problems are connected but I do want to get both fixed without spending $$$ at the dealership. Where can I start?
View 5 RepliesI turned on my AC... set the temp to 62 degrees (pressed AUTO and pressed the button where all the AC controls are all the same temp) ... And its blowing out warm air.. Left it running for about 5 minutes and still no sign of cold air.... Am I doing something wrong? do i not know how to turn on the AC?
View 6 RepliesI have a 2004 4.2. Touareg A/C is only blowing warm air. I ran Vag-com no codes. I used a gauge to check refrigerant ,the system was empty. I added refrigerant, i could see it increase and then decrease immediately. The A/C then work for a while then started blowing warm again. Used the gauge again ...empty. I then noticed clear oil on the ground. There is a drip from underneath front drivers side , looks like from a small silver canister by radiator.
I'm thinking about adding dye and looking for the leak. Is this A DIY fix or should I just take it to a mechanic. I've replaced the timing belt, brakes, drive shaft and a few other repairs. I hate taking this car to a mechanic, they always have issues.
2001 DOHC AC all of a sudden started blowing warm air when on max AC, not regular cabin air but warm air as if it is on heater mode. It has automatic climate control. I checked the charge and low side is 30psi and high side about 130 psi. Pipes in engine bay are sweating so cooling is occurring. The compressor cycles once or twice when I first turn the car on then just runs continuously. I put some charge in but it didn't do anything so I didn't want to overcharge it. I was thinking maybe stuck blend door but how would I check for that.
View 3 RepliesBrought my Touraeg in due to a/c occasionally blowing warm. Works 95% of the time. Also, while driving pops up warning light that says "Electronics: Consumers being shut off" this seems to somewhat coincide with the a/c issue. Dealer just called and said I have leaves in my system and need new pollen filter---- and not covered by warranty--- Does not make sense to me-- first we have covered parking and limited leaves in area--- also if leaves then why would it work perfectly sometimes and not others?
View 6 RepliesSo the other day my ac had a hiccup and wouldn't blow any cold air. Ac button was on, LO temp setting, and it just blew warm humid air for about 10 mins. I finally pulled over and tried turning ac button off and on and still no luck. Finally I shut the car off, turned it back on and it instantly blew cold. It's been a few days and it hasn't happened again, but I find myself questioning whether it will work every time. It's 110 here in Phoenix so ac is basically a necessity. I know the dealer won't be able to replicate it so I don't really want to waste my time.

View 4 RepliesMy wifes car AC just started blowing warm. I figured it was getting a little low on refrigerant. So I went and bought a can with the gauge on top, and I connected it and it was reading half way into the red zone....way overcharged. But nobody has put any in the system since we bought the car over a year ago. The AC has been great for all this time. So how can it be blowing warm and be overcharged that much without overheating the cars engine ? The clutch is coming on with the compressor?
View 4 RepliesTemp knob is turned full to hottest setting and heat only blows warm. I checked the hose from the IACV and hose from just past the Thermostat housing and they are also hot. Where the hose enters the "Damper" just outside the firewall, it is hot but the small portion of hose after the damper into the firewall is only moderately warm. Is it possible that damper is clogged or is the heating coil iside the car clogged?

View 19 RepliesMy 2006 Sonata GLS 3.3 A/C started blowing warm, so I checked all the fuses and they were good. Swapped the relays and still nothing so I check the wire to the compressor and it was reading 14v. This would lead me to believe the a/c clutch is bad, I didn't want to replace just the clutch incase my compressor craps out on me later on so I'm just replacing the whole thing now. My questions is how much oil does a new compressor need?
View 3 RepliesWas just on a trip (about 200 miles or so each way) and the AC worked just fine.
Car has sat for a few days unused.....when I used it to day, the AC blows warm...doesnt cool at all.
I hooked up a gauge to the low pressure side and the pressure reads very high (in the red zone of the gauge).....
Cant tell if the compressor is kicking on or not when the car is running...
Car is 600 miles out of warranty (of course).
Yesterday the AC worked fine, until I got off work. Then it was blowing as usual, but almost warm air, it wasn't enough to cool the car. When driving and I turn it on, I do see the RPM's lower slightly. A co-worker looked at the compressor and clutch while I turned it on and he said they both are working. He did not see any bubbles in the little window on the line though. The light on the control button is not blinking and the in cabin filter isn't dirty.

View 2 RepliesMy Prius has 198K, runs great and has been trouble free. This week it started acting up. The AC will run for a few minutes, blowing very cold, then will blow warm air for a period of time, perhaps 10 minutes, then will blow cold again for a few minutes. It will repeat this several times, then will blow cold until the end of the trip, about another 30 minutes.
View 7 RepliesI have an 05 prius that has been a great car 193,000 miles with no issues, until now. AC started blowing warm air so took it to mechanic who replaced the compressor. Blew cold for a day and started blowing warm again. Took it back to mechanic replaced the evaporator. Same thing blew cold for a day and then warm air next day.
Mechanic told me to take it to Toyota to get it looked at and they said 3 way coolant valve so we replaced that and still blowing warm air. Took it back to Toyota for the second time and they said it was a bad compressor so we replaced that and still no cold air. No AC in Florida summer is getting old fast need to get this fixed.
