Service Procedure

The following procedure provides instructions for installing an in-line fuse wiring harness at the exterior power mirror switch located in the left front (driver's) door.

1. Open the driver's door and verify that the exterior power mirrors function properly.

2. If either or both mirrors do not function properly, see the appropriate service manual for diagnosis and repair BEFORE proceeding. Parts and labor for performing repairs to the power mirrors are the responsibility of the vehicle owner and are NOT covered by this recall.

3. Disconnect the negative battery cable.

4. Remove the panel (bezel) that holds the power mirror switch. See the Door Subsection in the Body and Accessories Section of the appropriate service manual it additional information is needed.

^ On C/K and S/T model vehicles, using a flat-bladed tool, carefully pry the bezel up from the door trim panel.

^ On M/L model vehicles, carefully remove the screw covers on the assist handle. Remove the assist handle screws and the screw attaching the front corner of the bezel to the door trim panel. Carefully pull the bezel away from the door trim panel.





5. Disconnect the electrical connector (2) from the power mirror switch (1).





6. Using GM12094429 (electrical terminal release tool) contained in J 38125-B (Terminal Repair kit), remove the terminal and BROWN wire from cavity "G" (2) and the terminal and ORANGE wire from cavity "H" (1) of the harness electrical connector. The letters "G" and "H" can be found on the harness connector.





Important

The two wires must be installed in the correct cavities of the new connector in the next step. The cavities can be identified by a small letter (A & B) located at the end of the connector where the terminals are to be inserted.

7. Take the two wires and terminals removed from the harness electrical connector and insert them in the two cavity loose connector provided in the recall kit.

Insert the BROWN wire (1) in cavity "B". a Insert the ORANGE wire (2) in cavity "A".

8. Verify that both terminals are locked in the connector by LIGHTLY pulling on the wire.





9. Insert the gray terminal position assurance (1) included in the recall kit into the end of the connector where the two wires stick out. When properly installed a "click" type sound will be heard.





10. Take the new two-cavity connector (1) that you just installed the two wires into, and plug it into the two-cavity connector (2) on the fused wiring harness included in the recall kit. When properly installed a "click" type sound will be heard.





Important

The two wires must be installed in the correct cavities of the connector in the next step. The cavities can be identified by a small letter (G & H) located on the connector.

11. Take the two wires and terminals located on the other end of the fused wiring harness and insert them in the two cavities in the electrical connector that was disconnected from the power mirror switch.

^ Insert the BROWN wire and terminal (2) into cavity "G".

^ Insert the ORANGE wire and terminal (1) into cavity "H".

12. Verify that both terminals are locked in the connector by LIGHTLY pulling on the two wires.





13. Connect the harness connector to the power mirror switch. When connected, the completed assembly should appear as shown.

14. Reconnect the negative battery cable.

15. Verify that the power mirrors operate correctly.





16. To prevent rattles, wrap the fused wiring harness as shown with the foam tape (1) included in the recall kit.
