- Driver Side Power Window Auto Up / Down Function does not Operate with Power Window Master Switch

DESCRIPTION

If the manual up and down functions operate normally but the auto up and down functions do not, then the fail-safe mode may be functioning.

If the power window initialization Initialization has not been performed, the auto up and down functions will not operate.

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 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 multiplex network master switch assembly at the auto up position, and opened manually by pushing down the multiplex network master switch assembly.
