Fig. 11: Disconnecting 16P Connector

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, make the following input tests at the connector.

If a 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.

4. With the master switch still disconnected, make these 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, go to step 5.

MASTER SWITCH INPUT TEST (DISCONNECTED)

5. Reconnect the 16P connector to the power window master switch. Turn the
