Air Conditioning (A/C) Clutch

NOTE: This applies to OEM, factory installed air conditioning.

DESCRIPTION
An electromagnetic A/C clutch is energized when the A/C cycling switch closes. The A/C cycling switch is located on the suction accumulator/drier. The closing of the switch contacts completes the circuit to the A/C clutch and draws it into engagement with the compressor driveshaft. The powertrain control module uses this signal to adjust EPC pressure when the air conditioning 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.
