2010 Lexus RX 450h 3.5 BFACTORY OEM SERVICE PROCEDURE

Front Passenger Side Power Window does not Operate with Front Passenger Side Power Window Switch (To 8/2009): Description

When the hybrid vehicle control system is running or the power switch is on (IG), the power window regulator motor assembly (for front passenger side) is operated by the power window regulator switch assembly (for front passenger side). The power window regulator motor assembly (for front passenger side) has motor, regulator, and ECU functions.

HINT:Β 

If the pulse sensor built into the power window regulator motor assembly (for front passenger side) malfunctions, the power window control system enters fail-safe mode. The remote up and down and auto up and down functions cannot be operated during fail-safe mode. However, the power window can be closed by holding the power window regulator switch assembly (for front passenger side) at the auto up position, and opened manually by pushing down the power window regulator switch assembly (for front passenger side).
