Compressor Clutch: Testing and Inspection

The air-conditioning compressor clutch electrical circuit is controlled by the engine controller computer located in the engine compartment outboard of
the battery.

If the compressor clutch does not engage, verify refrigerant charge.

If the compressor clutch still does not engage, check for battery voltage at the low pressure or differential pressure cut-off switch located on the 
expansion valve. If voltage is not detected, refer to:

1. Diagrams/Electrical.
2. Powertrain Management/Computer and Controls/Testing and Inspection/Procedures.
3. Compressor Clutch Diagnosis.
