Window Switch Operation

When the ignition switch is in RUN, battery voltage is applied to the window switches through circuit breaker 3, the PNK wires, the window Lock-Out switch, PNK/BLK wires to terminal A. See WIRING DIAGRAMS  . When the UP switch in the window switch is operated, battery voltage is applied to the window motor. The motor is grounded through the BRN wire, the DN contact in the window switch, and the DN contact in the master switch assembly. The motor runs to drive the window up. When the DN switch in the window switch is operated, battery voltage is applied to the window motor in the opposite direction. The motor is grounded through the UP contact in the window switch and the UP contact in the master switch assembly. The motor runs to drive the window down

Each motor is protected by an electronic circuit breaker. If a window switch is held too long with the window obstructed or after the window is fully up or down, the circuit breaker opens the circuit. The circuit breakers have positive temperature coefficients (PTC) and reset automatically when voltage is removed from the motors.
