01 E320 giving me a problem that is a mystery. All interior and exterior lamp are working fine. #11 fuse keeps blowing with the instrument lights, symbol lights, and license plate lights going out. I have repeately check the bulbs, but can seem to determine what is the problems. Everytime I replace the fuse and drive for several minutes after turning on the headlights, the #11 fuse (instrument lights, interior symbol lights, & license plates lights) blows with the Defective Lamp malfunction appearing on the dash. Any ideas as to what could be the source of the problem?
