A/C Compressor

A/C COMPRESSOR

The A/C compressor for the rear A/C system is located on the right side of the engine and driven through an electric clutch, drive pulley and belt arrangement. The rear A/C compressor is lubricated by refrigerant oil that is circulated throughout the rear refrigerant system with the refrigerant.

The rear A/C compressor draws in low-pressure refrigerant vapor from the rear A/C evaporator through its suction port. It then compresses the refrigerant into a high-pressure, high-temperature refrigerant vapor, which is then pumped to the rear A/C condenser through the compressor discharge port.

CAUTION: Be certain to adjust the refrigerant system oil level when replacing an A/C compressor. Failure to properly adjust the refrigerant oil level can prevent the rear A/C system from operating as designed and can cause serious A/C compressor damage.

The rear A/C compressor cannot be repaired and must be replaced if inoperative or damaged. The compressor clutch, pulley and bearing assembly, and clutch field coil are available for service. If an internal failure of the rear A/C compressor has occurred, the rear A/C receiver/drier must also be replaced.
