So yesterday I went out to my uncles house out in Murrietta CA where it is about 101-108 degrees out, almost arriving there my a/c starts to get warm and moist feeling. The a/c then came back and got mild cool until we got there. After being there for about 4-5 hours we left. While driving back home with the a/c on (that is not cold at all) , I hear a big swueal from under the hood and the a/c went really warm. I have an 03 CTS, can someone please help me? Thanks!

well if you need a new compressor, i believe somebody else is having this same problem if you do a search on here...the thread is on the 1st page of the forum...anyways, i believe he said that the dealer told him $1400, but i could be mistaken...

you could always get a used one for way cheaper...but rememeber, it would be used...might last forever, may last you a year...if you are interested in that option, then go to www.car-part.com

Just to let you know, if the system lost the charge. Then the compressor will not turn on, due to the fact that there is nothing there to compress.

Follow the directions on the charge system that you buy from the store. Personally I would spend the extra $3.00 for the system that comes with the gauge on it. You'll see what I mean. Start the engine, and put the climate control on MAX A/C with the fan all the way on high. Then put the coupler on the a/c low pressure side. I don't know which one it is. But connections should be labled with an "L" for low and "H" for high. Either way, that coupler will only attach to the low side.

Also check your belt and your idler pulley. Make sure that's all in good shape. In my experience, I found body shops more willing to help than Goodyear or Midas. The body shops are trainind, have the equipt and are looking for work.
