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 left window switch to circuit 1307. See WIRING DIAGRAMS  .

When the UP position in the right window switch is pressed, B+ is applied to the right window regulator motor through circuit 666. The motor is grounded through circuit 667, the down contact in the right window switch, circuit 167, and the down contact in the left window switch. The motor runs to drive the window up.

When the DN position in the right window switch is pressed, B+ is applied to the right window regulator motor in the opposite direction through circuit 667. See WIRING DIAGRAMS  . The motor is grounded through circuit 666, the up contact in the right window switch, circuit 166, and the up contact in the left window switch. The motor runs to drive the window down. The other windows operate similarly from their individual window switches.
