Auto Up / Down Function does not Operate

DESCRIPTION

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: 1) the PWR H-fuse or the power window relay (PWR) being replaced; or 2) the battery cable and the master switch's connector being disconnected.
- The master switch has a malfunction.
- The pulse sensors in the driver side power window regulator motor have a malfunction.
- The wiring between the master switch and the driver side power window regulator motor is open or short circuited.
