Power Window Motors

The front windows utilize non-smart window motors. Front and rear door window lift motors use permanent type magnets. The B(+) and ground applied at the motor terminal pins will cause the motor to rotate in one direction. Reversing current through the motor terminals will cause the motor to rotate in the opposite direction.

The rear windows use window smart motors. The BCM is responsible for passing rear window activation commands received over the LIN from the smart motors to the driver door switch bank module using the LIN bus. The window smart motors always inform the BCM about the current state of the windows. The smart motors are able to recognize the their respective window position and sends an appropriate status signal to the BCM.

The power window motors on this vehicle contain over current protection managed by the DDM/PDMs. The DDM/PDMs receive CAN-IHS ambient temperature values and an ignition off time signal from the BCM. The DDM/PDMs use these inputs do provide over current protection.

To initialize the window motors:

1. Move the window to the full closed position using manual mode.
2. The switch must continue to be held for a minimum of one second after the window reaches the full close position.
