[R129 SL] Windshield wiper

[Jan Kuylaars]

Tom.

The wipermotor stops in the middle of the windshield, so i
take off the housing ( 3 screws) from the wipermotor, bend the three
contactlips down so that the contactpoints were aligned with the three
contactrings and after cleaning the contactrings and replace the greese,
everything works fine for 10 months.

After that time the wiper stay's for a second in the middle , and then
go on.
I heard a click in the box on the right side from the car, where a lot
off electronics is settled.
I followed the cable from the wipermotor to the control box ,
disconnected the connector, and take out the control unit.
Ir was full of relay's with big contactpoints. I saw that some points
was burned-in. Tooke a smal piece off very little sandpaper and cleaned
the contactpoints. In the meantime the wiper system works without
problems for three jears.

Onderwerp: [R129 SL] Windshield wiper


The wiper on my 1990 500sl has started to park in various locations on 
the windshield leading me to believe that I need to lube the mechanism.

I'm wondering how the big cover is removed?

I didn't find any help in the archives and G. Murphy's article in the 
Star didn't apply to this model.

Thanks in advance for any help.
