CLK wipers only work when I spray water

[triston]

Hello All,
I have a CLK 240 convertible 2003 W209 model.

My wipers do not work anymore. The only way I can use them is when I physical press the "water spray" button.

Do you know what the problem is?

Could be the stalk contacts are dirty.

Does everything else on the stalk work?

The stalk seems to be ok

Everything else on the stalk works fine ...
