Control Unit Input Test
NOTE: The control unit only controls the driver's door
window.
Remove the driver's door panel and disconnect the 4P
and 6P 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.
