Question about GMC Sierra 1500
Hi, I recharged the ac, in my 95 gmc sierra pick up, the compressor went on one time, and that was it, it wont go on anymore.
There is an over pressure protection switch that could be at cause and there is an under pressure protection switch that might be at cause and there is also the on/off pressure switch located on the dryer canister that actually controls the temperature of your evaporator that might be just plain wore out. Last I remember NAPA wouldn't even stock these as they wear out within a month of use and just quit like your situation. My solution to that is to hot wire them on with a section of bare copper wire within the plug assembly - cu'mon GM you have to do better than that to stay slovent. Opps, too late.
So, what pressure(s) are you running and/or can you trace down the lack of electricty to your compressor's clutch? You've just started to trouble shoot this problem.
