General Information

A permanent motor operates each of the power windows. Each motor raises or lowers the glass when voltage is supplied to the motor. The direction that the motor turns depends on the polarity of the supply voltage that the switch provides.

The LH front power window master switch controls all of the window motors. The passenger window also has a separate switch.

Each motor is protected by a built-in circuit breaker. The circuit breaker opens the circuit if the window switch is held down too long and the following conditions apply:
^ The window is obstructed
^ The window is full up
^ The window is fully down

The circuit breaker automatically resets while cooling. When the ignition switch is turned to the RUN position, CKT 343 (YEL) supplies battery voltage to the LH front power window master switch.

When you operate any of the UP switches, battery voltage is supplied to the window motor. the voltage is grounded through the DN contact. The motor runs in order to drive the window up. When you operate any of the DN switches, battery voltage is supplied to the window motor in the opposite direction. The window motor is grounded through the UP contact. The motor runs in order to drive the window down.
