WINDOW / GLASS: POWER WINDOW CONTROL SYSTEM: Rear Power Window RH does not Operate with Rear Power Window Switch RH
- Rear Power Window RH does not Operate with Rear Power Window Switch RH

DESCRIPTION

When the engine is running or the ignition switch is ON, the rear power window regulator motor assembly RH is operated by the rear power window regulator switch assembly RH. The rear power window regulator motor assembly RH has motor, regulator, and ECU functions.

HINT
If the pulse sensor built into the rear power window regulator motor RH 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 RH at the auto up position, and opened manually by pushing down the rear power window regulator switch assembly RH.
