POWER WINDOW CONTROL SYSTEM Remote Up / Down Function does not Operate

DESCRIPTION

Front passenger door:

When the ignition switch is ON, the power window regulator master switch assembly sends remote up and down signals to the power window regulator motor assembly (for front passenger door) via LIN communication.

Rear doors:

When the ignition switch is ON, the power window regulator master switch assembly sends remote up and down signals to the rear power window regulator switch assembly (for LH door or RH door). Then, the rear power window regulator switch assembly (for LH door or RH door) drives each power window regulator motor assembly.
