Ok,
there has been mention two times about the possibility of rear bulbs being the culprit here. I know that MB Sprinter vans have problems when one puts a different bulb in the tail lite. Not sure if its a German thang but I did have a problem with my backup lights. didn't have an OEM replacement so I put in one 7057 bulb.
Kerpow, blown fuse. Changed out the other bulb so that both bases where metal (not one metal & one brass) and I have no more blown fuses. Though I do have another eletrical problem and wonder if the non OEM bulbs are the cause.
here's the link to my prob...
cutting out?
