94 C280 uni-wiper not moving
 

I hear the motor, but it does not move. Almost like it's become disconnected.

What's the best way to get inside to look at this?

Thanks.

Look at the post from " BoominBenz ". ;)

thank you...
 

Thanks. That will be a good start. I've already lubed the main wiper piston, but have not cracked the main drive open yet.

Thanks for the link, that looks like a great site!

And here is another one for you: http://members.lycos.nl/mbenz/windshield_wiper.htm

nuts
 

I got everything pulled out around the wiper and wiper motor and it appears that the nut that holds the wiper cam-arm to the motor has come off.

I'm going to the hardware store today to try to find the nut.

Any ideas on the size of the nut? I'm guessing between 10mm and 13mm???
