The sunroof and rear defroster does not work on my 92 400E. There are no sounds when trying to open the roof. I checked the fuse for these items and the fuse was fried. I bought a few new fuses and each time I started my car the new fuse would burst. I took this to a mercedes dealership and the service folks got the same results with more fuses.
They believe I may have a wiring problem. Does this sound familiar to any of you? And have anyone out there experience this type of problem, is it a costly one?
