Window control is activated via switches on the driver door module (DDM) (3/126) and passenger door module (PDM) (3/127). The motor for the power window on the driver's side (6/58) is controlled directly from the driver door module (DDM). The motor for the power window on the passenger side (6/60) is controlled via CAN communication from the driver door module (DDM) to the passenger door module (PDM). The signals for operating the rear windows are transmitted from the driver door module (DDM) via the controller area network (CAN) to the central electronic module (CEM) (4/56), which manages the rear window functions.

More detailed information about the rear windows and child locking can be found in Design and Function, central electronic module (CEM).

The passenger door module (PDM) only operates the front window on the passenger side. The signal for operating the front passenger window is transmitted from the passenger door module (PDM) to the window lift mechanism motor on the passenger side (6/60).

If the child lock is activated from the driver door module (DDM), the rear windows cannot be operated from the rear seat. When the child lock switch is activated, a signal is transmitted from the driver door module (DDM) on the controller area network (CAN) to the central electronic module (CEM) which disables rear window operation.
