LH Front Window Switch Operation

When the Ignition Switch is in "RUN," battery voltage is applied to the LF Window Switch through the PWR WDO/RR VENT Circuit Breaker and CKT 141. When either of the up switches in the LF Window Switch are operated, battery voltage is applied to the Window Regulator Motor. The Window Regulator Motor is grounded through the down contact in the LF Window Switch and CKT 750. The motor runs to drive the window up. When either of the down switches in the LF Window Switch are operated battery voltage is applied to the Window Regulator Motor in the opposite direction. The Window Regulator Motor is grounded through the up contact in the LF Window Switch. The motor runs to drive the window down.
