The A/C on my '88 635csi suddenly stopped working and I need to travel over 1000 mi next week. Need to get problem fixed this weekend.
Problem: Interior switches and fans work fine. When depressing A/C switch - no compressor clutch engagement. Put test light to wiring to compressor with switch on - no power. Took jumper wire and connected to compressor and positive power - clutch engages and everything works fine.
Must be a switch somewhere in the system, but I am not that familiar with A/C systems and how to test.
Any advice or ways in which I can get running this weekend so I have A/C next week would be greatly appreciated.
