The driver's window will stop and automatically open if you pinch your hand or something during auto-up operation. The system is composed of the power window master switch, the power window control unit and the driver's window motor.
The power window motor incorporates a pulser which generates pulses during the motor's operation and sends the pulses to the power window control unit. As soon as the power window control unit detects no pulses from the pulser, the control unit makes the power window motor stop and reverse.
