The wiper on die Frau's '95 C-220 has developed a strange problem. On any setting, between the ten and two o'clock positions, it moves very slowly, and then speeds up. Upon further observation, this is where the arm retracts to clear the top of the windshield. It also makes a "chunk" sound when it changes speed.
The blade is in good shape, and the glass is clean. Do not believe that it is resistance from the glass.
Relay? Motor? Anyone seen this before?
Thanks as always.
