The single wiper on my '89 190E 2.6 no longer works properly. The
sideways motion of the entire arm is fine but the up/down motion which
allows the wiper to cover the entire windsheld is mis-timed. It
extends outwards when the arm swings to the sides and also when it is
straight upright. As a result the top corners are not longer
reachable. If fact the normal size of the blades no longer fit
properly, I have had to switch to shorter wipers.
It all started while I was driving in heavy rain on a highway a couple
of months ago, when suddenly the wiper got stuck in one of the bottom
corners of the windsheld. I was forced to drive a couple of miles to a
safer area of the highway before I had a chance to unstick the
arm/blade. In the meantime, I did smell burning rubber before I came
to a stop.
Everything on the wiper else works well..just this in/out motion of
the arm, which extends and retracts at the wrong points on the
Any idea how I might solve this problem.
