Hi,

I own a 1997 E300D. Tonight, in a middle of a rain storm, my one and only wiper stopped doing its job of wipping its windshield.

I finally got home with no arms. When I turn the wiper on, I can hear the wiper motor running smoothly. The wiper itself does not move at all. In fact, I can move it myself from left to right. The wiper arm is free even if the wiper motor is turned off.

Any clue on what is causing this problem ? Should I order a new wiper transmission ? Please help on instruction to dismount this wiper

Thanks

Daniel

There are two reasons why your wiper may have stopped if the motor is still running, one of the nuts may have slackened on the drive linkage or the nylon gear in the drivehead is slipping/stripped. Either way the complete motor/drivehead unit has to come out to allow repair,in the first case it is just a matter of resyncronising the linkage and tightening the nut, the second is more complex.
This link shows the procedure for removal;http://members.lycos.nl/mbenz/windshield_wiper.htm.
PM me if you need any more help.

Pretty sure it's the loose nut on the linkage that attaches to the motor, shown in the link on the previous post. I've seen this a few times before.

Now why would anyone want their wiper blade to park pointing straight up? Just to be different, I guess. Looks pretty silly to me, but then again, many things people do to cars look pretty silly to me.

I'm sure " Gilly " only posted that link, to explain how the assembly comes apart.
Have you never watched the DTM ( Deutsche Tourenwagen Meisterschaft ), Germany's equal to NASCAR, only MUCH better racing.
They all run their cars with the wiper pointing straight up.

Manny, I didn't post the link, I only referred to it. Didn't even notice it was a 201, and that the knot head was trying to get the wiper to park vertically, what a moron....then didn't even get it straight up.

Thanks Shandy and Gilly.

You've been a great help for me.

The ball joint on the motor side assembly was disconnected due to a bad wear. The ball joint was rusty. I greased it, drill a 3/16" hole through the ball joint assembly and bolted it, so it will stay together.

While I got this thing in my hands, I greased the whole assembly and the wiper shaft as well. It is now running much more smoothly.

Once again, thanks for your support

Daniel
