AC quit blowing cold. Tried to recharge. Compressor wouldn't open. Unplugged high side pressure switch and jumped the plug with a wire. Compressor wouldn't open. Put it back together and drove 200 miles. Tried AC and it worked. 2 weeks later quit blowing cold and battery gauge on dash headed to red zone. Had alt/bat checked. They're fine. Unplugged switch again and battery gauge OK. Is the switch bad, or a short in wires between switch and compressor? Was I supposed to put the jumper wire on the switch instead of the plug?
Boy its hot here in GA
