VerifiedHi, my name is***** you remove the mag clutch relay and bypass the relay with a fused jumper does the clutch engage? If it does then I would have to suspect a fault with the engine control module or with the wiring between the module and the clutch relay.
Let me know what you find.
Marty
Hi Alex, if the lock sensor was at fault I would think that your a/c light would be flashing. I've attached the test procedure below. If the sensor checks out I would check the wiring from the clutch relay to the ECM. If you have voltage on the wire all the way to the ECM and there are no fault codes and the ECM is not grounding the wire to activate the relay I'd have to suggest trying a new ECM.
Compressor clutch circuit schematic below. Check all wiring from the compressor to control head to ECM.
The Engine Control Module is mounted on the floor, right side of the instrument panel, under the ECM protector.
