  3. Inspect the connector and socket terminals to be sure they are all making good contact.

    • If the terminals are bent, loose or corroded, repair them as necessary, and recheck the system.

    • If the terminals look OK, go to step 5.


  1. Reconnect the connector to the power mirror control unit, and do the following input tests:

    • If any test indicates a problem, find and correct the cause, then recheck the system.

    • If all the input tests prove OK, go to step 6.
