Hi all.

My rear wiper won't turn off on my A6 2008 avant. I've searched on the forums but they all mention water leaking through. The jets are working fine and there doesn't seem to be any water leaking anywhere and it's dry inside when I remove the little plastic hatch. It was raining heavily the day this started happening so I wondered if anyone had any ideas on what it could be. I'm about to go on a long journey so will remove the fuse for now.
