What does the AC compressor in a truck do?

Asked by Dutchess_III (46828points) April 19th, 2011

Most importantly, is it critical? We gave my daughter a 95 Suburban. It hasn’t had AC for the last two year, no big deal. Recently it started making some noise. She had a couple of home grown mechanics look at it. They said it was her AC compressor. However, they said, it runs more than the AC. It cools the whole engine down, or something. One told her it could catch on fire if she left the truck idling, the other told her the truck could flat lock up on her at any moment.

Needless to say, she parked it immediately while we try to figure out how to get a part (how to afford it is the main thing) and find someone to install it.

Can any of you give me any further info? It’s a 95 GMC Suburban 1500, 7.5 liter , 4WD.

If we can find a decent used compressor, what should we expect to pay for installation?
