DIS shows that all the doors are open if i open the driver door.
Door lights and footwell lights doesn´t work either.

Any ideas what is wrong?

In the trunk there is a black box on the right side under the fuses. What is that?
Some earlyer owner has disconnect one of two positive wires from that box. Is there some reason why he had done that?
