Power Window Switch: Description and Operation
Rear Center Console Power Window Switch Combination, Function
The left rear power window switch in the rear center console (S21/15s1) actuates the left rear power window motor (M10/5) and the right power window
switch in the rear center console (S21/15s2) actuates the right rear power window motor (M10/6).
Switch positions and associated functions:
Middle position
Non-actuated position
Press switch

NOTE:
The switches are designed as polarity reversal switches. This means that the polarity of the power to the motors can be reversed (depending on running
direction).
In the non-actuated state, both motor connections are switched via the switch contacts to the center console switch group (S21) so that the rear power
windows can also be operated from the front.
