354742 - M35 ONE OF THE REAR WINDOW MECHANISMS IS NOT WORKING AUTOMATICALLY

One of the rear door windows (left or right) only works manually; when the control button is pressed for longer than 300 ms and then released, the window does not open/close automatically, but stops.
The Luggage Compartment Node is programmed to move the windows up and down, both manually and automatically. The luggage compartment node activates the manual function if the control button is pressed for beween 50 and 300 ms (briefly), whilst the automatic function is activated if the control button is pressed for longer than 300 ms (long period).
