Master Switch Assembly Operation

When the ignition switch is in RUN, battery voltage is applied to the master switch assembly through circuit breaker 3 and the PNK wire. See WIRING DIAGRAMS  .

When any of the UP switches in the master switch assembly not associated with express down are operated, battery voltage is applied to the window motor. The window motor is grounded through the DN contact in the master switch assembly. The motor runs to drive the window up. When any of the DN switches in the master switch assembly are operated, battery voltage is applied to the window motor in the opposite direction. The window motor is grounded through the UP contact in the master switch assembly. The motor runs to drive the window down.
