Air Conditioning (A/C) Clutch

DESCRIPTION
The electromagnetic A/C clutch is energized when the A/C cycling switch closes. The switch is located on the suction accumulator/drier. The closing of the switch completes the circuit to the clutch and draws it into engagement with the compressor driveshaft. The powertrain control module adjusts EPC pressure when the A/C clutch is engaged to compensate for additional load on the engine.

Symptoms:
- Failed "ON" - EPC pressure slightly low with A/C OFF.
- Failed "OFF" - EPC pressure slightly high with A/C ON.

DTC:
P1460
