Wiper Woe

[CIL 7015]

The passenger side wiper isn't working but the drivers side is on my W211. Any suggestions what to check.
Thanks for your help

Check the nut is done up.

Thanks Checked it nice and tight. Do the wipers have separate motors or a shared one

Shared one. I think one of the arms has come off.

Remove the lower screen trim and its all under there.
