Was warm on idle cold when driving, used AC PRO to put in refrigerant. Then compressor cycled quickly then stopped. When engine off pressure gauge is in the red. Not sure on wiring diagram but I bypassed the relay and not compressor. The relay socket has 12 vdc on two of the terminals with engine running. Is there more to the power portion of the compressor circuit than fuse, relay contacts and compressor? Where is the pressure switch in the circuit? I hope I am clear.
