My air conditioning seemed like it wasnt blowing air as cold as it used to. We tried to charge it but now it seems to be blowing hotter air than before. Is it possible to overcharge it and could that be the problem?

Hey folks. Newbie here. I have a 2005 Chevrolet Equinox with 3.4L V6 I purchased from a new/used car dealer here in Kansas City. I say that primarily so that you know that I purchased it from a dealer that not only sells used GM cars, but new ones as well (and they haven't been ordered closed). I purchased it with 32,000 miles on it back in November 2008, but out of factory warranty as I now have 41,000 miles and it's older than 3 years. I also have since passed the 3 month/3,000 mile warranty the dealer provides. As summer has come on. I noticed a strange occurrence as I've begun using the A/C. On the passenger side of the car, the two vents were blowing pretty cold air, but the driver side two vents were blowing warmer air. I noticed this a couple of weeks ago after I started using the A/C. I thought it was odd, and I jumped out of the car and looked under the hood. (I know nothing about cars, so bare with me here), I could see the metal hose with, what appeared to be the freon filler nozzle, and it was dripping from condensation and was cold to the touch (I assume that is the way it is supposed to be). Fast forward a week or two, and it's been really pretty hot the past couple of days, and it hasn't seemingly been working as wel, but that's partly probably because it's so hot, but it still is blowing cooler air on the passenger side of the car than it is on the drivers side. I also noticed today, that metal line that was dripping because of condensation, was no longer cold today with the engine running and the a/c going. I could, however, hear the compressor kick on and off when I turned the A/C on and off. Does that sound like I have two problems? My friend told me he thought perhaps teh doors that controlled where the air was blowing from behind the dash was faulty, and that was why half teh vents were cool, and half weren't. But I also assume that metal hose is supposed to be cold, and it's not. Please don't tell me I have two problems Sad EEK!

In addition, how do you think I should handle it with the dealer. Again, this wasn't some corner car lot, this was a major dealership that has several different dealerships here in the KC Metro that sell everything from Nissan's, Acura's, etc. To Chevrolets that I only purchased it from 7 months ago in the dead of winter when I wouldn't have been aware of an A/C problem. They apparently went through some 150 point inspection, but you know how that goes. Don't you think the dealership should work with me, and perhaps pay for at least the labor, if I pay for the parts? Any help/input/advice is appreciated on this matter.

Thanks in advance.

I did. It was low on freon. I had them pressure check it. And it didn't lose any pressure. The dealer recharged and it's been fine every since blowing very cold air.

In the summer time my airconditioner only gets sort of cold when I am actually driving down the road. When my car is stopped the cold air stops. So I had my dad look at it, who was a mechanic, and he filled it with Freon as much as is normal and we tried it out for awhile and it didn't help so he looked at it again and noticed the blower fan only came on in spurts can you tell me what is wrong and how much it would cost me to fix. Thank you

The fan was probably cycling with the ac compressor, and if its low on Freon it will do that, called short cycling. Your vehicle holds 1.76 lbs of 134a. If it has a large leak it may have already leaked out, and if it has a small leak you may not have put enough in. If it was completely empty and moisture got in then you wont get good coolin until the moisture is removed. To do this youll need to replace the accumulator, which has a dryer in it. Then itll need to be put into a vacuum and leak checked. But first, look at the container of Freon you put in, or one like it. Most are only 12 ozs. That means youd need two and a third of these cans if your system was empty.

My ac blows cold whild the car has power. As soon as the car starts ideling the ac blows warm/cool air. When I took it to the shop they said it was either the compressor or the condensor, maybe both. My understanding is that if it is one of these than I should not have cold air period. Am I wrong? Did they give me the wrong diagnosis?

If it is working when you are moving and then warms when you idle, chances are either the freon is low or the radiator fan isn't working.

Have that checked. When the compressor goes, it will usually lock up and make a lot of noise.

I added refrigerant to my 05 equinox. Not it is pushing outcool air. It is pusing hot air and spitting out antifreeze. What does this mean andlso does the line need to be evacuated before adding the refrigerant

Spitting out coolant-sounds like the heater core is leaking-inspect thoroughly

When u press on the gas the antifreeze is kicking out. So what would allow the ac not to push out cool air?

Are you talking about antifreeze or freon? If its freon the evaporator is leaking and would caused an AC problem-No cool air

The anitfreeze is what is spraying out when I press on the gas. It is spraying out from the bottom of car. When the hood was open it looked like a puff of smoke came out when it did that

My AC has been out for about a year now. We replaced compressor, dryer/receiver, as well as expansion valve. It blew cool air for about 45 minutes after and went out again. We had it vacuum and refilled and it blew cool air until the next morning and went out again. At this point we decided to check for leaks. UV dye and blacklight showed no leak so we vacuumed it down and refilled yet again. It is now holding pressure on the low side at 40 PSI however the high side is measuring on two different gauges at 50 PSI. The compressor is clicking on and off but not building pressure. Again the compressor is new (not used or remanufactured). I have had several mechanics take a look but still no luck. Any help would be wonderful.

Bring it in and have it pressure tested to identify where its leaking at cannot do it from here-

I assume the compressor went bad originally. When this happens the lines need to beflushed out backwards to get all the crap out that the compressor put in there when it blew. EVen wha tyou have done has just probably wrecked the new compressor because from your description this wasn't done. Sounds like the compressor let go again.
