Theory Of Operation

WARNING: This page is about a different car, the 2016 Dodge Durango. However, it is still accessible from the selected car via links, so may be relevant.

If both of the Window Driver circuits (Up and Down) are grounded during a window movement command, the motor will be totally inoperative. To lower the window, voltage is applied to the Window Driver (Down) circuit and the Window Driver (UP) circuit remains grounded in the module. To drive the window up, the circuits are reversed.
