POWER WINDOW CONTROL SYSTEM Driver Side Power Window does not Operate with Power Window Master Switch

DESCRIPTION

When the engine switch is on (IG), the power window regulator motor assembly LH (for LHD) or power window regulator motor assembly RH (for RHD) is operated by the multiplex network master switch assembly. The power window regulator motor assembly LH (for LHD) or power window regulator motor assembly RH (for RHD) has motor, regulator and ECU functions.
