Title: WINDOW / GLASS: POWER WINDOW CONTROL SYSTEM: Front Passenger Side Power Window does not Operate with Front Passenger Side Power Window Switch; 2016 - 2020 MY Sienna [12/2015 -        ]

Front Passenger Side Power Window does not Operate with Front Passenger Side Power Window Switch

DESCRIPTION

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

HINT:

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