So it's 100 degrees in Texas and I'm thinking a little A/C would be nice. My compressor is good, the system is charged and the clutch engages when powered, but I'm not getting power to the clutch from the switch. I know there are relays for the A/C condenser fan, a diode and a relay for the compressor clutch by the battery, and there is a pressure switch on the accumulator. I have a wiring diagram but what I don't have is a breakdown, i.e.how the electricity flows, to the clutch. I have changed out all the relays by the battery to no effect. Anybody have any tips on tracing down the A/C wiring to find my open? I didn't find much when I searched in the forums.
BTW, the condenser fan is running when the A/C switch is on so that system is working as intended. I see something about a delay A/C relay unit under the dash on the passenger side, not sure what that is about but wondering if it's an issue.
