Help Diagnosing A/C Comp. Clutch
Hello all,
My 06 1500 WT V6 compressor went out a while ago. I've checked the refrigerant pressures and those are ok, no signs of leakage. Pressure switches have continuity. I have jumped the relay for a short time and the compressor runs fine and pumped out cool air immediately. All other fuses involved are fine. Now I am stumped at where the issue could be. I removed the HVAC controller and inspected the connectors and wiring... they look fine, the leads on the wiring harness had voltage. Is it just a faulty controller? One of the LEDs for the temp control died several years ago and I have read that those arent the most reliable pieces of equipment on the trucks. Perhaps the ECM? Should I just bite the bullet and have a shop try and diagnose it? I hate paying people to do repairs.
Thanks,
Chris
