Rear Power Window LH does not Operate with Rear Power Window Switch LH |
DESCRIPTION
When the engine is running or the ignition switch is ON, the rear power window regulator motor assembly LH is operated by the rear power window regulator switch assembly LH. The power window regulator motor has motor, regulator, and ECU functions.
HINT:
If the pulse sensor built into the rear power window regulator motor assembly LH malfunctions, the power window control system enters fail-safe mode. The remote up/down and auto up/down functions cannot be operated during fail-safe mode. However, the power window can be closed by holding the rear power window regulator switch assembly LH at the auto up position, and opened manually by pushing down the rear power window regulator switch assembly LH.
