Air Conditioning Clutch (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 A/C clutch and draws it into engagement with the compressor driveshaft.

When engaged, the A/C clutch is an input to the PCM to adjust EPC pressure for the load on the engine. Also used to adjust Torque Converter Clutch(TCC) modulation when the A/C clutch is engaged.

SYMPTOMS
- Failed ON - EPC pressure slightly low with A/C OFF.
- Failed OFF - EPC pressure slightly high with A/C ON.
- If erratic A/C operation occurs, the customer may feel improper TCC apply and release.
