Master Window Switch Operation

When the ignition switch is in the RUN position, battery voltage is available through the PWR WDO circuit breaker and CKT 343 (YEL) to the left front door lock and side window switch. The operation of the left front wind up switch supplies battery voltage to the left front window regulator motor through CKT 164 (DK BLU). The window motor grounds through CKT 165 (BRN) and through the window switch down contact.

The regulator motor runs in order to drive upward the window. The operation of the down switch supplies battery voltage in the opposite direction to the window regulator motor through CKT 165 (BRN). The window regulator grounds through CKT 164 (DK BLU) and the window switch up contact. The motor runs in order to drive downward the window.
