Prius (2004-09) :: 2007 - A/C Won't Blow Cold Air?
Aug 21, 2015
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.

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.

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?).

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.

Sometimes when I hit the start button it takes a couple of minutes for the AC to start blowing air. I even tried stopping and shutting off and restarting but it still took a few minutes to start blowing. It doesn't do this all the time just every now and then.

I have an issue with my a/c. The left side blows out air but it is not cold. The right side is cold. The whole front dash has 4 vents total so the left two does not blow out cold air at all.

Cannot figure out how to get the heated air to flow through the back via the rear vents. All I get is outside air. I cannot find anything about it in the manual. The dealer has no clue but is trying to find something on it. New 2009 Santa Fe Limited.

I own a 2007 Camry LE. It's 4 cylinder and has 80k miles. Since I can remember, the A/C takes a really long time to start blowing cold air.
I'm in Miami, where ambient temp is about 90 F every day and it takes about 2-3 minutes to blow cold air. I can tell because this usually happens when I get around a certain street (SW 40th Street), so the problem is self-replicating regularly.
My father is a house A/C mechanic and he filled it with refrigerant but this has not fixed the problem. If the car has been driven and been parked under shade, the A/C blows cold air since the start. After being driven for 2-3 minutes, it blows cold air like a monster, I usually have to run it on 70 % cold and low fan - that's how well it performs.

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.

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.

I have owned my 2008 Rx 400 h for just over two months now and at the risk of sounding dense, am I right in assuming that when you are coasting along without the engine running, the heater will start to blow cold air? Everything works fine until you lift your foot off the pedal. This is my first Lexus/Toyota and hybrid so I'm not totally au fait with how it should be working.

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

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.

I have a 2007 F150 with a 5.4. I am having an issue with my A/C and more.
Here are the symptoms:
1) A/C doesn't blow cold, at times.
2) Compressor not coming on, according to mechanic.
3) Engine sounds like a freight train, at times. Like on a super cold day and it has to work hard.
4) Very poor fuel mileage since this started.
I took it to a shop, and they said it was the engine cooling fan that would not come on. So I replaced it. Same issue. I then took it back and was told there is a wiring problem. After 3 days they couldn't find it. I needed my truck back and dropped it off again. Then they said it was the A/C compressor, maybe. They wanted to try it and then see what happened. I told them no way.
Temperature, according to the gauge is good. Noise comes and goes. Not dependent on anything. Weather, temperature, car heated up or dead cold. Just comes and goes.

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.

2007 Prius with ~133k miles:
We bought it used a little over a year ago and haven't any problems with it at all until now. Last night from a cold start, the check engine light came on along with the red triangle of doom. Checked the oil, it's fine, just had it changed a few weeks ago. Did the battery test, it's fine, 12.2v during the test and 14v with a load. Popped the hood, and I can see little waves in the pink inverter fluid when the car is in Ready. A drive around the block revealed that it's not running well at all... It could barely make it up a small hill.
