Interior lighting is crazy!

Hello, I have problems with the interior lighting again and again, which partly does what she wants. Normally the lighting goes on when unlocking the rear and front, and when starting the car it should extinguish itself again. But now it is phased so that this does not always work. It can also happen that the left lamp turns on itself during the ride. With the friendly one nothing could be determined. Of course is also a stupid problem welc Is there anyone else here? Greetings Jürgen
