Master Window Switch

With the Ignition Switch in "RUN," battery voltage is applied to the Master Window Switch via CKT 141. The switch assembly is grounded via CKT 150. When any Master Window Switch "UP" switch not associated with express down is operated, battery voltage is applied to the Window Motor. The motor is grounded through the "DN" contact in the Master Window Switch, and it runs to drive the window up.

When a Master Window Switch "DN" switch is pressed past the first detent, battery voltage is applied to the Window Motor in the opposite direction. The motor is grounded through the "UP" contact in the Master Window Switch, and it runs to drive the window down.
