My dash lights in my E34 stay on after I turn off the lights. The only way I can turn them off is to pull the LKM which ofcoarse disables my headlights. I checked the fuses and found nothing so I assumed the LKM was faulty. I purchased a used one and it didn't fix the problem. Either I now have 2 fualty LKM's or the problem is elsewhere.

Does anyone know what the problem could be?

Regards....
