Power Window System: Overview

Each power window is moved by a single permanent magnet motor. The direction the motor turns depends on the polarity of the supply voltage. The control switches control the supply voltage polarity. Switches for controlling both power windows are located at the driver's door. The passenger's window switch controls only the passenger's window glass. The motors have a self-resetting circuit breaker built in. The circuit breaker allows the motor to be stalled without damage. There are no travel-limit switches.
