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

DESCRIPTION

With the ignition switch ON, the power window regulator master switch assembly transmits remote switch signals to the power window regulator switches of the front passenger side power window and rear power windows. Then, each power window regulator switch drives its respective power window regulator motor*1 or door window regulator*2.
