Description

Power Window Key-off Timer Operation:
The power windows can still be operated for about ten minutes after the ignition switch is turned from the "II" to the "I"
or "O" position as long as neither of the doors has been opened. This provides a convenience to parked occupants while
offering a degree of security against unwanted or accidental window operation.ProCarManuals.com

Control Unit Input Test

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.
