Prius (2004-09) :: AC Blowing But Air Wasn't Cold - Evaporator Replacement?
Oct 22, 2011
My a/c was blowing but the air wasn't cold. No freon, so the dealer loaded up with freon containing a tracer. After a week, the tracer is coming out of the evaporator drain only, which implicates the evaporator as the source of the leak.
I just hit 150K miles and was extolling my repair free existence, when I had to do the front struts, brakes, and new tires (again); followed by this. Can't find a reference to evaporator leaks anywhere (a lot of mold maybe, but nothing requiring replacement. Did my luck just run out, or is this more common than I think?

Well my a/c stopped blowing cold last week so I took it to an a/c shop and they said it was really low on freon. The guy recharged it and we noticed the driver side fan wasn't turning on. Said that it was causing to much pressure and it was blessing it off causing the loss of freon. So I came home and put it on the lift to check out the fans. I unplugged the fans from the bottom side below the fcm and the pass side fan comes on with a 12v source but when I put power to the other plug (drivers side fan) there's nothing across the high or low side. Guessing the fan is toast right? Just making sure before I order a new fan. What's all involved in replacing the fan? Also I've read the vw fans have a resistor that are known for burning out. Should I go with oem or a different brand from ecs?

I have a 2012 truck that the AC wasn't blowing cold air this summer so I took it in and they said nothing was wrong... Took back in and they replaced vent control... worked a little bit. Fall came and my windows fog up and really never clears up so I take it in and they said it is blowing hot air but I told them that isn't the problem but the moister in the cab is the problem. I feel I'm getting the run around.

Last week while on the highway I noticed my AC was not blowing cold. It was set to the lowest temperature and at the lowest fan setting. The air had gone from cold to room temperature and the AC button light was flashing/blinking.
I pressed the button, it lit up solid and it started blowing cold again. Two minutes later the air went back to room temperature and the light was flashing again.
It worked fine for a few days and then it happened again Saturday. I noticed the air wasn't coming out cold and see that the AC button is blinking. I tap it solid and it starts blowing cold again only this time it stayed cold for the rest of the 20 minute drive. What could be going on here?

I had my A/C compressor unplugged over the winter, and now that I've plugged it back in, the A/C is not blowing cold. Is there some kind of programming reset that needs to be done?

I have an 06 Prius. I was driving my Prius today and I've noticed that my car has NO HOT AIR...
And this is Winter!! I was driving for about 20 mins and still...No Hot air...vents are blowing cold (cool) air.
I recently changed my condenser/radiator but I did NOT fill my condensor with the A/C gas yet. (could that be the problem?) But isn't the gas inside condenser is for A/C and not for the Hot air??
Any other stuff that I need to check to solve this problem?? (harness, fuse etc.?) It's cold outside and my car has NO HEAT!

So from the beginning the car wasn't coming on. It gave me error "p" said my parking break was not working properly and needed to be on a flat surface in order to work. We jumped it and replaced the battery shortly after that. The car will turn on but the actual engine is not turning on. The display screen has a little car with a red exclamation going through it. The dashboard also has all the lights on. We have tried to jump it from the relay at this point but it wont start now to where before it would.

I've seen several posts regarding the warning lights, mine is a bit different. My Warning Light, Maint Reqd, ((!)), and engine light are all on. I've driven it a few times since and notice that after driving for 10 minutes or so, the VSC light also comes on. In one instance the brake light also came on. At that point my AC seems to also stop blowing COLD air. The motor blower motor still runs, but the air is no longer cold. Battery checks out. Coolant levels are good. Code indicated "something with the inverter cooling" according to local garage. Suggested I take it to the dealer. Scheduled for a trip to dealer tomorrow but wondering if there's anything I can/should do in the meantime.

My wife and I are on a 2400 mile cross country road trip road trip and we just got a check engine light about 12 hours away from home. The check engine light, VSC, and tons of other lights appeared. Shortly after our cruise control disengaged and then A/C stopped blowing cold air. We were cruising along in 100F degree weather at about 75-80mph climbing a 10-mile incline with the AC on full blast.
We got to a Toyota dealership but they are closed until Monday so we'd have to wait 2 days for them to check it out. We went to pep boys and they found the code to be "Drive Motor B" which they said should be fixed by Toyota dealership (but he said he didn't really know what the issue is).
I did a quick search and found this might be the inverter coolant pump. Like another poster, I found the car seems to work okay when the AC is off.

I have a 2005 Prius that financed from a small dealer last year. Currently has over 140k miles on it. When I bought it it had the Red Triangle and it worked fine until recently (about 2 months ago). Recently I've been having some problems. When I go at higher speeds I get the following sings come on:
1. Red Triangle
3. Orange check engine light
2. Orange (Symbol)CHECK - Malfunction Indicator Lamp
3. Orange (!) - Brake Warning Light
4. Orange VSC - Vehicle Stability Control Warning Light
When these lights are on, my AC stops blowing cold air. Sometimes when all these lights are on, the car will slow down and will not let me go past 37 MPH I have to then pull over turn the car off and then on, then the lights turn off and I can drive normal, on short trips that is.
Recently on a longer trip over 50 miles or so all the lights I mentioned came on plus the red break light on the left turned on with a continuous beep. We pulled off the HWY and turned the car off then on and the lights disappeared except for the big red Triangle that one is always on. We continued driving it but it kept doing it so we had to let it rest for over 30 minutes. We had to take it really slow and we finally got to our destination.
Codes P08A3 and P0A37 Prius 2005....

My problems in my ac begin last year around Summer. My ac was blowing hot and not cold and once it even blew some kind of smoke out of the vents. It only did that once and hasn't since. I went to good year and put some freon in the car. And it started to blow cold again and I was good for a while. Well I didn't need the cold air for the last few months till the heat started up again.

I'm putting a new evaporator into my '87 F250. The manuals I have give conflicting numbers on how much oil I should add to the system. How much oil is needed in this replacement? Also, do I add the oil to the accumulator or pour it into the new evaporator?

In January I had to replace my engine in a 2007 Toyota Yaris. Last week we had the first day, since the engine replacement, that I needed to use the air. The fan blows air, it just isn't cold. Could this be anything to do with the engine replacement? Maybe they didn't hook something up properly? Do the drain the coolant to the ac when they take out the engine? I have been reading that it may simply be a fuse or needs to be charged. I realize I should have checked the a/c when I picked it up, but at -8 below, air conditioning doesn't cross your mind.

My wife's 2000 Jeep Cherokee has a failing A/C system. Last year it was blowing warm air in the middle of the summer so I took it to a local mechanic who recharged the freon and it was fine through the rest of the summer. This year it is blowing warm again so we took it in for another recharge and it only lasted a few days. The mechanic said there is a leak at the evaporator coil(?) He said the entire dash needs to be removed to repair and it would run about $1000 to fix. This seems a bit steep. Any thoughts or experience with this issue?

I have a Toyota Corolla 2003. I need to replace the expansion valve and the evaporator of the AC. I have been told I have to remove the whole dash to do that. Is that true? and if so, where I can find a video or a step by step guide in how to do that?

My husband and I have a 2007 Yaris (purchased new in May '07) with 23,300 miles on it. He's super-religious about taking the car in and getting it serviced and maintained regularly. But we noticed a few days ago that the A/C wasn't putting out cold air. My first thought is that it's simply out of freon and needs to be serviced.
But it just seems odd (or at least to this know-nothing!) that it could be out of freon already. My husband mainly drives it and says he doesn't run the air "any more than anyone else." Is it possible that even at 14 months it's just simply out of freon? I've never heard of a car's A/C system running out of freon so quickly.
Also, we were out of town for a week; the car wasn't driven during that time. We noticed the problem the first time we drove it upon returning home. That couldn't have anything to do with it, could it?

Replacing the evaporator? I am just curious how big of a job it is. I have the a/c equipment to service the system. Its on my 01 f-250 with a 7.3.

So here's the deal...my '99 Sub has developed the problem of the A/C running too cold and freezing up the evaporator.The specs call for the clutch cycle switch to shut off the compressor at 25 lbs-low side, and turn it back on at 45 lbs. With a static pressure of 120 lbs, ambient air temp of 85 degrees, engine idle 1200 RPM: when the system is turned on the compressor activates and the low side pressure stabilizes at around 30-34 lbs...the high side sits at around 180-200 lbs...fan on high, max setting on temp control, the middle-front register reads 28-36 degrees.
This is great for awhile until the evap freezes up and airflow is restricted. The lowside pressure will not drop down to 25 lbs to activate the switch to shut off the compressor. I even installed a new pressure cycle switch to no avail since the pressure will not drop enough to activate it anyway. So every half hour or so, I have to manually shut off the compressor at the control panel for about 5 minutes, and then start the process over again. The rear unit is controlled by the TXV and continues to function just fine (rear register temp 36-40 degrees).

I have a 2004 2nd generation Toyota Harrier (Lexus model RX330). The A/C blowing hot air if temperature is not set to Max Cold. This happened no matter whether turn on the A/C with Auto or Manual setting. This case also happen no matter whether setting the A/C system to Dual mode or not, no matter whether turn on or off the air intake control button.
As long as A/C on, cold air only come out when temperature set to Max Cold, even if set to 18 degree, full hot air come out. Another thing is, say I have the A/C on, set to max cold, cold air came out from the front vent, but after I try to increase the temperature to say 18 degree, the hot air flow will change to Floor/Windshield mode.
Could it because due to the change of the battery? Is there anything need to reset after replacing the battery?

It seems my A/C isn't blowing cold air all the time. It's as if the compressor isn't kicking on or is intermittent. It eventually does, but it takes a long time to cool the vehicle. I've had it about 6 years and it has definitely changed. Vehicle is an '04 with 106K now.

Right now it's 101 degrees outside and the A/C on my Prius just ain't gettin' the job done. It doesn't even feel like it's blowing cool air anymore, just lukewarm air. How can I cool down the cabin more? Temps like this only happen a couple times a year here. What do Prius owners do in places like Pheonix where 100+ temps are the norm?
