POWER WINDOW CONTROL SYSTEM (w/ Jam Protection Function) - 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 assembly, was erased as a result of: 1) the PWR H-fuse or DOOR fuse being replaced; or 2) the battery cable and the master switch's connector being disconnected.
- The power window regulator master switch assembly has a malfunction.
- The pulse sensors in the front door window regulator sub-assembly (for driver side) have a malfunction.
- The wiring between the power window regulator master switch assembly and the front door window regulator sub-assembly (for driver side) is open or short-circuited.
