Ford - Fivehundred :: 2005 - AC Will Blow Cold When Running Fast And Then Blow Hot

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.

Prius (2004-09) :: AC Only Blow Cold Air If Temp Is Set At MAX Cold

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.

Prius (2004-09) :: 2007 - A/C Won't Blow Cold Air?

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.

Prius (2004-09) :: AC Blow Cool But Not Cold And Unpleasant Whining Noise

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.

Camry :: 2005 - A/C Malfunction - Don't Blow Really Cold Air

The a/c on my '05 Camry still puts out cool air, but not really cold anymore. I compare with my '08 Highlander that can still freeze your arms off in no time. We have had a warm spell lately, which is supposed to continue for another week, and while the Camry is putting out enough to eventually cool the air, it's just not up to it's usual standard. Are these a/c systems supposed to be sealed, and if so, is a leak the most likely reason ? I have not had it serviced in the past 3 years I've owned it. Is it worth it to try the "do-it-yourself" canned a/c service bottles or should I get the system pressure checked out first ?

Passat (B5) :: 2005 - AC Malfunction / Blow Hot Air And Sometimes Cold

2 weeks ago my ac on my 2005 passat started working on and off, sometimes it would blow hot air and sometimes it would blow cold air. I took it to an independent shop (which we trust, they been working on our cars for a long time and never been ripped off...but first time I've taken a Volkswagen to them) and they just did an AC diagnostic test and re-filled the Freon, replaced the filter...it worked for 1 hour and went back to blowing hot air again, so I took it back and they said a valve stem was loose, causing the AC to work sometimes and not others, so they replaced that with a new one, my AC worked for 4 days...than on the 5th day it blew hot air again.. What could possibly be causing this??? It is stressing me out, especially since I need AC in hot Houston summer weather.

Prius (2010-12) :: AC Doesn't Blow 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.

Lexus RX 2004-09 :: Heater Will Start To Blow Cold Air

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.

Toyota - Highlander :: 2005 - Passenger Side A/C Vents Blow Cold Air But Driver Side Hot

History - So my A/C was going out about 6 months ago. It would come in and out with cold air until eventually it just stopped all cold air and was only hot. Then the control knobs broke. I took it in and they told me I had to replace the control unit and that would fix all the issues. Well I got it back and the A/C was still blowing hot air (even though the knobs were now working).

So I took it back in and they said they couldn't find anything wrong and it must be this hairline crack that was leaking freon. they said they couldn't find the crack but loaded it up with freon and said i would have to 'wait it out' could be years could be a few weeks, they just didn't know. well, it worked for awhile but here i am in 102 degree heat and when I turn on the A/C in the really hot car the passenger side quickly blows cold air and the driver side takes about 20 minutes before it finally gets cold. What gives? I do not have dual temperature controls.

Prius (2010-12) :: AC Light Comes On, Fans Blow Hard, But No Cold Air

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.

Ford F-150 (2004-2008) :: AC Does Not Blow Cold At Times / Compressor Not Coming On

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.

Prius (2004-09) :: 2005 - Shifting Out Of Gear In Cold Weather?

My 2005 Prius shifts into Neutral, "N", when I put it either into Drive, "D", or Reverse, "R", during Cold weather, mid 20's and below. It will only stay in "B" to drive, and I have to hold the shifter in "R" to back up or "D" to drive. After the car warms up while driving 15-20 minutes in "B", I can shift it into "D" and it will stay there. I normally start the car and let it warm up in the morning for 10-15 minutes on cold days, below 25F but still I'm only able to drive it in "B" until it's ready. I just moved to Montana after driving this car in normal Southern California driving conditions. It happened while vacationing in Montana during the winter of 2007 a few times but it didn't bother me since I wasn't living there. I reported to Toyota but they couldn't do anything since the weather wouldn't co-operate. This car is still under 70,000 miles.

Prius (2010-12) :: AC No Longer Blow Cold Air And Rubber Smell When Heater Is On

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.
