WARNING: This page is about a different car, the 2009 Mercedes-Benz CLK350 and 2008 Mercedes-Benz CLK350. However, it is still accessible from the selected car via links, so may be relevant.
The power window switches (S20/1s1, S20/1s2, S20/1s3 and S20/1s4) in the driver-side power window switch group (S20/1) transmit the desired adjustment request to the left door control module (N69/1), which then relays this information to the CAN class B bus.
The left rear power window switch (S21/3) and right rear power window switch (S21/4) can be inhibited with the rear side window child safety lock switch (S20/1s5)
The switch status is indicated by a marking
