Window Express Down Feature

Both windows are equipped with the Express Down feature. This feature allows a window to be fully opened by momentarily pressing the window switch to the second detente of the Down position. The passenger window can be expressed down from either the appropriate window switch built into the driver door switch assembly (DDSA) or from the window switch mounted to the passenger door. When either switch is operated to Express Down, both the Down contacts and the Express contacts of the switch being used are closed to ground and the signal is interpreted as an Express Down request. If the window is operated from the passenger door window switch, the passenger door module (PDM) interprets the signal and the window is lowered. If the passenger window is operated from the driver door, the DDSA interprets the signal and communicates via class 2 serial data with the PDM to request the Express Down command to lower the window.

If a door module loses power for any reason such as a vehicle battery disconnect, the power window must be reinitialized once power has been restored. For more detailed information concerning power window reinitialization refer to Power Window Reinitialization .
