Circuit Operation

A Permanent Magnet (PM) motor operates each of the power windows. Each motor raises or lowers the glass if voltage is supplied to the motor. The polarity of the supply voltage determines in which direction the motor turns. The window switches control the supply voltage polarity.

A built-in circuit breaker protects each motor. The circuit breaker opens the circuit if a window switch is held too long and one of the following conditions exists:
^ The window is obstructed.
^ The window is fully up or down.

The circuit breaker resets only after the voltage is removed from the motor.
