Driver's Window

When the driver's switch of the power window master switch is pushed to DOWN or pulled to UP, the signal for down or up is sent to the control unit. The control unit provides power and ground to the driver's power window motor, lowering or raising the window until the switch is released.

When the driver's switch is pushed to AUTO DOWN or pulled to AUTO UP, the signal for auto down or auto up is sent to the control unit. The control unit provides power and ground to the driver's power window motor, lowering or raising the window. As the window descends or ascends, the pulser in the driver's power window motor sends pulsing signals to the control unit. When the window reaches the fully down or fully up position, the pulsing signal stops, and the control unit removes power and ground from the driver's power window motor. If something obstructs the window during the AUTO UP operation, the control unit will detect no pulses from the pulser. For safety reasons, the control unit will make the driver's power window motor stop immediately and reverse.
