I noticed on my '92 300E that the windshield washers don't work either. I got to investigating after the light in the dash came on. The little pumps on the bottom of the reservoir just touching them emit windshield solvent. Also, someone cut the line off that goes to the one for the windshield. It looks to have two electrical wires inside of the plastic pipe. Is there some other electrical connection this one makes? Can parts be gotten for the reservoir pumps such as new seals or does the whole works come as one unit? Thanks for your help!!
