Window Switch Circuit Operation

When the ignition switch is in RUN, battery voltage is applied to the window switches through the WDO circuit breaker and the PNK wires to terminal A. See WIRING DIAGRAMS  . When the UP switch in the right from window switch is operated, battery voltage is applied to the right front window motor through the DK BLU wire. The motor is grounded through the BRN wire, the down contact in the right from window switch, the TAN wire and the DOWN contact in the master switch assembly.

The motor runs to drive the window up. When the DOWN switch in the right from window switch is operated, battery voltage is applied to the right from 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 and from window switch, the DK BLU/WHT wire and the up contact in the master switch assembly. The motor runs to drive the window down. The other windows operate similarly from their individual window switches.
