My wiper on my 95' C280 make a "thud" noise and stopped in the middle
of the windshield on the return stroke. I assumed I blew a fuse but
it is OK. Then I noticed that when I hold on to the wiper (which moves
with relative freedom now) and turn the wiper control on and off it
feels as if the motor is cycling but it has become disconnected from
the wiper arm itself. I assume there is a nut with a spline shaft as
on others but I don't know for sure. I think I hear the motor but it
has always worked quietly on this car since the dealer replaced it
right after I bought it.
I do not have the body manuals for the car. Can anyone tell me
briefly how to remove the wiper motor cover / motor for inspection?
Any help is greatly appreciated.
