I can't seem to activate my A/C clutch. When I turn on the switch with engine idling, there is a slight increase in RPM, which is normal, and indicates the switch is working. I tested the relay (switched with the horn relay) and it is working fine. The 10A fuse is not blown. Would the A/C diode 'fuse' cause this problem? I wouldn't think so. I don't know how to test the diode, but I found it doesn't have continuity, which I suspect is normal. Anyone know how to check the diode? If the diode is OK, are there any other things to check before testing the clutch itself? What is the best way to test the clutch?
