Power Windows
Descriptions
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 puls-
es 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.
