Auto Up/Down Function Does Not Operate On Driver Side

AUTO UP/DOWN FUNCTION DOES NOT OPERATE ON DRIVER SIDE

CIRCUIT DESCRIPTION
The power window regulator master switch controls the driver's power window and activates the driver's 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 or the power window master switch connector being disconnected.
- The pulse sensor in the power window regulator motor has a malfunction.
- The wiring between the power window master switch and the corresponding power window regulator motor is open or short circuited.
- The power window master switch has a malfunction.
