6. Disconnect the air mix actuator electrical connector (2).

Important: The single zone HVAC module only has the one 22 pin connector. The dual zone HVAC module has a 22 pin connector and a 7 pin connector. The tri zone HVAC module has a 22 pin connector, a 7 pin connector and a 10 pin connector.

7. Disconnect the HVAC module electrical connectors (3) as required.

Important: The evaporator temperature sensor is part of the wiring harness.

Important: Using a suitable tool, raise the evaporator temperature sensor locating clip (2) to clear the locking recess in the HVAC module assembly (3) and turn the evaporator temperature sensor (1) 45 degrees clockwise to remove evaporator temperature sensor (1) from the HVAC module assembly (3).

8. Remove evaporator temperature sensor (1) from the HVAC module assembly (3).

Important: Use a pair of long nose pliers to close the wiring harness retaining clip (1) ends to remove the wiring harness retaining clips (1) from the HVAC module assembly (2)

9. Detach the wiring harness retaining clips (1) from the under side of the HVAC module assembly (2).

Important: The inside air temperature sensor aspirator venturi is only fitted to dual and tri zone HVAC module assemblies. Ignore steps 11 and 12 if working on a single zone HVAC equipped vehicle.

10. Detach the inside air temperature sensor aspirator venturi tube (4) from the HVAC module assembly retaining clip (1)

Important: Rotate the inside air temperature sensor aspirator venturi (3) clockwise to disengage the inside air temperature sensor aspirator venturi (3) retaining clips from the HVAC module assembly (2).

11. Remove the inside air temperature sensor aspirator venturi (3) and inside air temperature sensor aspirator venturi tube (4) from the HVAC module assembly (2).
12. Disconnect the face/floor actuator electrical connector (1).

Important: The drivers side air mix actuator is only fitted to dual and tri zone HVAC module assemblies. Ignore this step if working on a single zone HVAC equipped vehicle.

13. Disconnect the drivers side air mix actuator electrical connector (2) if equipped.
