A/C Compressor Failure

1. Vehicles that have an inoperative A/C compressor, due to internal causes, should have the refrigerant system cleaned by flushing or filtering. This removes any debris or contaminants that may be present to prevent damage to the replacement A/C compressor.
The suction accumulator/drier and A/C evaporator core orifice cannot be cleaned and must be replaced.
2. Remove the A/C evaporator core orifice.

NOTE: A dirty A/C evaporator core orifice or a condenser to evaporator tube containing black refrigerant oil and particles indicates that the A/C compressor has failed and must be replaced.

3. Remove the A/C compressor.

NOTE: Residual refrigerant oil in the A/C compressor must be drained and measured for proper system oil matching.

4. Remove the suction accumulator/drier.

NOTE: Residual refrigerant oil in the suction accumulator/drier must be drained and measured for proper oil system matching.

5. Clean the A/C evaporator core and the A/C condenser core by flushing.

NOTE: System flushing is the preferred method of cleaning. However, if flushing equipment is not available, system filtering may be performed as an alternative.

6. Install the replacement A/C compressor.
7. Install the replacement suction accumulator/drier.
8. Install the replacement A/C evaporator core orifice.
9. Properly oil match the system.
10. Evacuate and charge the system. Evacuation and Charging
