Prius (2010-12) :: AC Light Comes On, Fans Blow Hard, But No Cold Air
Jul 30, 2014
I just bought my 2010 Prius from a Toyota dealer a few weeks ago. It has 103,000 miles, so it's not under warranty.
I thought the a/c was a bit weak when I got the car, but I always drive it in Eco mode, so I thought that was the reason. It wasn't terrible, just wasn't "ice" cold. Well, today it has completely kicked the bucket. Nothing. A/C light comes on, fans blow hard, but no cold air.

A few weeks ago, I bought a new condenser, compressor, evaporator, expansion valve, ac line for my 2010, 200000 mile Prius and had them installed by a dealership. They weren't too happy about my independent purchase of parts , but they did the job.. After a few days, there was no longer cold air. The dealership is 1000 miles from where I live. They are willing to start over again, for free, and see where the leak is but I can't travel to there for awhile, and, already the heat is oppressive in the middle of the day. I asked the local dealership if they would run a test of the system which will be a bit expensive, and they agreed. But, they cannot guarantee that the test will be conclusive. After almost 3000 dollars spent on this, I really do not know where to go from here.

Abridged version: My fans won't blow any air out of the vents. If I spin the blower/fan motor that is behind the glove compartment, it'll work again. But the cycle repeats itself every time I turn the car on.

How does the A/C still blow cold air with the engine not running?

I took my 200000 mile Prius to a garage that is highly recommended and the mechanic stated that I need a new evaporator and expansion valve. He tested the car for a day. There was no time to do the fix so I arranged for a dealership that I trust to do the job. When they were ready to do the work, they detected no leak in the evaporator, but said that the compressor, expansion valve, and AC line needed replacement. (They showed me the leak in the compressor with special glasses.) After I called the first mechanic with the new info, he said that he could detect a leak nowhere, but, in the evaporator, and, at the expansion valve area. I am now stymied as to what I should do.

My 2005 Prius is having a problem with the AC. It will only blow cold air if the temp is set at MAX COLD. Any other temp setting and it will blow hot air. Really hot air. It makes no difference what the outside or inside temps are. Is there a simple fix for this? I can control the AC by setting it on Max Cold and changing the fan speed, but I would like for it to work on the auto setting the way it is supposed to.

CURRENT PROBLEM:The fans don't blow any air after about 30 minutes of driving/once the car has warmed up.Also, A/C seems to permanently be on even if I don't have the A/C button on, but the fan problem is the main issue(There has been a loud hum behind the dash (for over a year) that speeds up the faster I set the fan speed so the motor is going but no air comes out.)
What's happened in the past:
1. Last summer the A/C stopped working. Will have to look back at receipts more to see exactly what was done (not sure if it worked through winter).
2. Basically the heat only came out of the vent to the left of the steering wheel all winter (no air came out of other vents or it barely came out but was cold).
3. A/C wasn't blowing cold so they replaced thermo switch. When they did this, car wouldn't do anything so they replaced the computer (fortunately I didn't pay for that).

I'm at the end of my rope! My 2005 Ford Five Hundred Limited has a constant problem with the A/C system and overheating. In the last year I've replaced the compress, expansion valve, dryer FOUR times. They have replaced the condenser, blower motor, and added Freon, and checked for leaks. It will blow cold when running fast and then blow hot. They have replaced belts pulleys, They have replaced the thermostat, fans, coolant reservoir, hoses. and it still overheats. I've taken it to 4 difference mechanics including two dealerships. No one can seem to fix this problem.

Just passed 30 months and 30k miles in my 2012 TDI SEL and suddenly the air conditioning fans blow harder as I press on the accelerator pedal.
To be more clear, as I accelerate, I can hear the windshield/defogger fans blow harder. When I let up on the accelerator the fan noise dies down. I tried adjusting the A/C settings to blow to the middle or feet only, and also enabling/disabling cabin air circulation. It only seems to be the defogger fans that do this.

When I'm stopped at a red light for a while I notice that my car doesn't blow cold air anymore, there's tons of blowing but feels like its just normal outside air being blown into the cabin even with re circulation on and AC on.
I've tried turning the AC on and off again at the light, and nothing changes...
I also notice sometimes the AC would decide to blow a little stronger, then let off again. Not sure if the problem is RPM related , i.e. IDLE issue or what.
Just wanted to see what fellow i45+ owners had in mind to what could be causing this issue... I've read something about condenser being clogged, and what not, but I have to be sure.
It works again and starts blowing cold air as long as I'm moving, so I guess it's not that big of an issue, but the hot temperatures here in South Florida can surely give you heat strokes in matter of minutes.

So, my A/C in the 2005 doesn't blow cold. It blows, just not cold.
The dealer recommended doing an evac/recharge, which, from what i understand, is there way of finding out where I have a leak.
I took it to my local shop, since the dealer wanted a lot of cash to do this. After having my car in their lot all day, the local fellows called me to say that they couldn't do any recharging/service on my A/C since the coolant is something only the dealer can get (which is a special kind of coolant with special lube in it, right?).

My 2007 Prius does not blow cold air, I bought the car back in March, when the weather was cold, so I never used the AC. I don't use the AC at all, I always roll my windows down if it ever gets too hot, but I recently have guests over, and I turned the AC on as I thought it would be a better and comfortable drive for my guests who are in town.
Anywho, the AC doesn't work. I obviously feel air, and I feel the apropriate levels (low, medium, high), but the temperature is just warm. It is set all the way to the lowest. I was going to fill up the refrigerant, but after doing some research, I quickly stopped and saw that the Prius has a very complex approach to its AC system. I am not sure if this is really a compressor issue, or just having low levels of refrigerant, but I'd love to get down to a basic diagnosis so I can understand what my costs are, and what potential issues it can cause.

I have a 2005 Prius, purchased 5 months ago with 100k miles, and it currently has 106,000 miles.
The air conditioning blows cool, but not cold. When the A/C is turned on, it makes an unpleasant whining noise. I have a recording of it.
It did not make this noise 5 months ago, and the A/C output was colder then. I haven't used the A/C that much over the winter, but it's starting to warm up now and I've noticed it's not doing as well as it used to, and it isn't sounding very good either.

I slammed on my brakes the other day because a car pulled out in front of me. When i let off the brakes i noticed the car did not move for a good 1-2 seconds and a traction control light was flashing. I didn't think much of it until i was sitting at a light and decided to see what happens if i press my brake pedals in hard again... the traction light turns on again and the car doesn't move when brakes are disengaged for a few seconds. Is this normal? It feels like my hill assist on the BMW. Why the traction light turns on? My car is a 2010 Prius III with 5k miles.

I installed an Injen cold air intake and 2 days later, the check engine light went on. I had it reset at the dealer and next day, again. Am I stuck with this or is there a way to keep it off, other than putting back the original air box?

I have a 2013 Prius 4. I'm not sure if there is a problem or not but the heater just seems to blow the same temperature of air no matter how high I set the temperature. The air feels lukewarm. I was driving 60 miles yesterday with the temperature set at 76. I had on a long sleeve shirt and polar fleece jacket and it never got to where I was really warm. Outside temp was about 50.

I sat in the back of my recently purchased 2011 Prius Three, not III, for the first time yesterday. I learned from this forum that the vent in the rear seat is to keep the hybrid battery cooled. However, while sitting the back during a ride, I noticed it was blowing air out instead of sucking air. I would think the vent should be sucking air from the cabin to keep it cool, but that does not seem to be the case here. After a 30 minute drive, I even felt the air coming out of it was warm and the A/C began to feel that it was not enough for my area in the back of the car.

I can't seem to get the engine temp to middle range on the marker, but yet my heater blows "to me" hot air. Even while sitting in idle for extended amounts of time I cannot get it to "operating" temperature. I would think if my thermostat was stuck open my heater would blow either cold or slightly warm air. I have the 5.4L engine with knn air filter and no cats.

The last few times I drove my car, I noticed the A/C didn't feel very cold. I checked today, and noticed that neither cooling fan comes on with the A/C on. My understanding is that both fans should be in LOW mode with the A/C on. Also, after idling for a while and even after doing some spirited driving and pulling over, the fans never turned on.
From what I'm reading, this sounds like it probably is either the fan control module or the fans themselves failed. Is the fact that both fans don't work in either high or low speed point to this being more likely to be a fan control module? Would this show up as a fault code on a VAG-Com scan?
