A nice Sunday for all inclined readers! The interior lighting of my Vivaro does not react to open/close the door. However, if I sit in the car for a while and turn on the interior lighting (medium switch position), the bulb lights up until it runs out automatically. I then open the driver’s door (or that of the passenger), the interior is illuminated, wants to say, the lamp dimmes up, but then does not go out any more, even if I open the driver’s cabin v lock it. But it doesn’t do that on its own. So, I unlock the vehicle and open the door, it doesn’t give me enlightenment. I hope I could explain my problem half-way plausibly. At first, there is no “enlightenment” of the problem. The door switches seem to work, all other functions, especially the extinguishing of the lamp after closing and not locking the doors. Is there actually a control unit that can have a Macke?
