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.
