Window Switch Operation

Battery voltage is applied to the window switches through the retained accessory power circuit breaker and the power window battery feed circuit to the left front window switch and then through the lockout control circuit to all the switches when the ignition switch is in the ACCY or RUN position.

Battery voltage to raise the window is applied to the window regulator motor through the directional drive circuit when the window switch is pressed in the UP position. The motor is grounded through the down directional drive circuit in the window switch and the down contact in the left front window switch. The motor runs to drive the window up.

Battery voltage to lower the window is applied to the window regulator motor in the opposite direction through the down directional drive circuit. The motor is grounded through the UP directional drive circuit for the window and the up contact in the left front window switch. The motor runs to drive the window down.
