2002 GMC Envoy Question: AIR CONDITIONER WON'T TURN OFF

 

Question

Visitor, Livermore, ME, April 13, 2010, 06:31

For the last couple of months; we've notice when we want to just have outside air or heat; it seem that the air conditioner just stays on.

What could the problem be and what would it cost?

Sincerely,
Pauline Demers

    I have the same problem. I changed the compressor relay but that didn't correct it. Spraying the compressor clutch with WD40 worked for a short time, so I think maybe the compressor clutch staying engaged is the problem. Due to the cost, I haven't changed the compressor...yet. Please let me know if you find anything that works.
