Windows: Description and Operation

A permanent magnet motor operates each of the side windows. Each motor raises or lowers the glass when voltage is supplied to that motor. The direction the motor turns depends on the polarity of the supply voltage. The side window switches control the supply voltage polarity.

The left front door lock and side window switch controls all the motors. The other window switches controls only the window regulator in that door.

Each motor is protected by a built-in 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 breaker resets automatically as it cools.
