Window Switch Operation

When the ignition switch is in the accessory or on position, B+ is applied to the window switches through the PWR WINDOWS PWR SUNROOF circuit breaker to circuit 143, and then through the LF window switch to circuit 1307. When the UP position in the RF window switch is pressed, B+ is applied to the RF window regulator motor through circuit 666. The motor is grounded through circuit 667, the down contact in the RF window switch, circuit 167, and the down contact in the LF window switch. The motor runs to drive the window up. When the DN position in the RF window switch is pressed, B+ is applied to the RF window regulator motor in the opposite direction through circuit 667. The motor is grounded through circuit 666, the up contact in the RF window switch, circuit 166, and the up contact in the LF window switch. The motor runs to drive the window down. The other windows operate similarly from their individual window switches.
