Control unit for window lifter makes noises

The window lifters and the sliding roof on my V8 didn't work, new original control unit was brought to the Bosch service, built in, window lifter and sliding roof
They work again.
Now the control unit in the passenger footroom makes strong noises and the lighting of the FH - switch burns permanently.
This wouldn't bother me so much, but the side effect of an empty battery is really bothering me.
Can somebody tell me the reason for this?
I am above every tip or tip. I'm grateful for the suggestion.

Oh yes, when the rear door is open on the driver's side it is also buzzing in the door.
