2. Remove the driver's door panel Service and Repair.

3. Disconnect the 24P connector (A) from the power mirror control unit (B).





4. 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.

5. With the connector still disconnected, do these input tests at the connectors.

- If any test indicates a problem, find and correct the cause, then recheck the system.
- If all the input tests prove OK, the control unit must be faulty; replace it.
