NOTE: The control unit only controls the driver’s door
window.
Remove the driver’s door panel and disconnect the 4-P
and 6-P connectors from the control unit.
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 control unit
must be faulty; replace it.
