Air Conditioning (A/C) Clutch

NOTE: OEM Factory Installed.





DESCRIPTION
The electromagnetic A/C clutch is energized when the A/C cycling switch closes. The switch is located on the suction accumulator/dryer. 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.
