DESCRIPTION
When the engine is running or the ignition switch is ON, the power window regulator motor assembly (for driver side) is operated by the power window regulator 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 power window regulator master switch assembly at the auto up position, and opened manually by pushing down the power window regulator master switch assembly.
