[W126 Coupe] Windshield Wiper

[Camran Nassiri]

Hi Dick- You are so right about the fuse.  It looked good and was not severed as far as I could see.  I replaced it with one of the spare ones in the fuse box and that didn't work either (perhaps old and corroded as well).  A new fuse and cleaning the contacts was the remedy.

Thanks for your help.

Thanks,
Camran
