Front Passenger Power Window Operation

The switch for the front passenger power window has 3 positions Up, Down and Express Down, and its position is a direct input into the passenger door switch (PDS). Upon receiving a request for power window operation (switch activation), the PDS supplies voltage to the power window motor right front up or down circuit and grounds the opposite and the power window motor runs to drive the window up or down.

The front passenger power window can also be operated from the driver door switch (DDS). The front passenger window switch on the DDS has 3 positions Up, Down and Express Down and its position is a direct input into the DDS. Upon receiving a request for front passenger power window operation, the DDS transmits a GMLAN message indicating the changed switch position. When the PDS receives this message, the PDS supplies voltage to the power window motor right front up or down circuit and grounds the opposite and the power window motor runs to move the window up or down.
