Right Window Switch Operation

When the ignition switch is in RUN position, battery voltage is supplied to the right window switch through the PWR WDO circuit breaker and the PNK wires to terminal A. When the UP switch in the right window switch is operated, battery voltage is applied to the right window motor through the DK BLU wire. See WIRING DIAGRAMS  . The motor is grounded through the BRN wire, the down contact in the right window switch, the TAN wire and the down contact in the master power window switch assembly. The motor runs to drive the window up.

When the Down switch in the right window switch is operated, battery voltage is supplied to the right window motor in the opposite direction through the BRN wire. The motor is grounded through the DK BLU wire, the UP contact in the right window switch, the DK BLU/WHT wire and the Up contact in the master power window switch assembly. The motor runs to drive the window down.
