NOTE:
• Before testing, go to the Troubleshooting Guide (see page

• All connector views are from the wire side of female terminals unless otherwise noted.

Multiplex Control Unit (Door):

1. Remove the driver's door panel, and disconnect the 20P connector from the door unit (see page

).

2. 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, make the following input tests at the connector.

If any test indicates a problem, find and correct the cause, then recheck the system.
If all the input tests prove OK, the power window master switch must be faulty; replace it.
