Circuit Operation

A Permanent Magnet (PM) motor operates each of the power window. Each motor raises or lowers the glass when voltage is supplied to it. The direction the motor turns depends on the polarity of the supply voltage. The switches control the supply voltage polarity.

The master switch assembly controls all of the motors. Each window switch controls only one of the motors.

Each motor is protected by a built-in self-resetting 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 breakers opens the circuit. The circuit breaker will not reset until voltage is removed from the motor.
