Driver Side Power Window does not Operate with Power Window Master Switch: Description
WARNING: This page is about a different car, the 2011 Lexus IS 350 and 2011 Lexus IS 250. However, it is still accessible from the selected car via links, so may be relevant.
When the engine is running or the engine switch is on (IG), the power window regulator motor assembly (for driver side) is operated by the multiplex network master switch assembly. The power window regulator motor assembly (for driver side) has motor, regulator, and ECU functions.
HINT:
If the pulse sensor built into the power window regulator motor assembly (for driver side) 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 multiplex network master switch assembly in the auto up position, and opened manually by pushing down the multiplex network master switch assembly.
