WINDSHIELD / WINDOWGLASS: POWER WINDOW CONTROL SYSTEM: Driver Side Power Window Auto Up / Down Function does not Operate with Power Window Master Switch

Driver Side Power Window Auto Up / Down Function does not Operate with Power Window Master Switch

DESCRIPTION

The power window regulator master switch controls the driver side power window and activates the driver side power window motor. If a malfunction is found in the pulse sensor during motor operation, the fail-safe function will stop UP/DOWN operation.
If the AUTO UP/DOWN function does not operate, the cause may be one or more of the following:

- The recorded power window fully closed position, which is stored in the power window regulator master switch, was erased as a result of the battery terminal cable or the power window regulator master switch connector being disconnected.
- The pulse sensor in the power window regulator motor has a malfunction.
- The wiring between the power window regulator master switch and the corresponding power window regulator motor is open or short circuited.
- The power window regulator master switch has a malfunction.
