Having problems with your 1998 GMC Sierra ?
I have a 1998 GMC Sierra. v-6 vortex. I get a real loud noise which seems to come from the a/c come from the compressor. It doesn't change when the a/c is on or off. The sound sounds like bearings on a boat trailer going out.
This is an old work truck and I don't want to sink alot of money into it. What will happen if I just let it go on making the noise?
A good possibilty is the compressor will lock up and either burn the serpentine belt off or a no start condition because it will not allow the engine to rotae.There is a less expensive alternative many of these trucks have an ac bypass kit available from auto zone or advanced that replaces the compressor with a bracket and a pulley in place of the compressor.
