Driver Side Power Window does not Operate with Power Window Master Switch |
DESCRIPTION
When the engine is running or the ignition switch is ON, the front power window regulator motor assembly LH is operated by the multiplex network master switch assembly. The front power window regulator motor assembly LH has motor, regulator, and ECU functions.
HINT:
If the pulse sensor built into the front power window regulator motor assembly LH 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 at the auto up position, and opened manually by pushing down the multiplex network master switch assembly.
