Wiper arm defunct on 114 720 250
Well it's started raining in LA and my first drive in it the drivers side wiper arm has come loose. The motor still works but the arm isn't moving with it anymore. I connect tell how it's connected to the motor so any ideas on how and if this can be fixed?

Hello,
Check the nut that holds the arm to the spindle first, this has been known to work loose, wiping off the serrations. Linkage rarely causes problems. Hope that helps.

Hello,
At the base of the wiper arm/shaft end, there is a cover cap that will need to be pried up from the *outer* end to expose the nut. Hope that is of some help.

The rivet is also the pivot for the cover. Pry gently upward at the base of the cover opposite the arm, it should flip up and expose a nut.
To check if the nut is loose try moving the arm in an arc. If the shaft at the base of the arm does not move, you have a loose nut. If it does move, the linkage is broken.

The shaft turns when the wipers are on so I'm sure it's not the linkage.

Well that worked.. It was not easy to get the cover to flip up.. I had to pry up the indentations on the sides first and then pry from the back edge by leveraging a screwdriver against a roll of electrical tape.
Tightening the nut up and it was good to go.

4.24pm your time is 3.24am for me...but alls well that ends well Mercedes wiper linkage rarely give any trouble, usually the soft alloy wiper arm cracks due to fatigue OR the base cone fitting gets wiped out. Have a good week
