Hi - My wife's car just did same. I couldn't find a fuse, but when we checked the motor was working. It turned out to be the wiper linkage on the motor had dropped off. Its a sort of ball pushed into a nylon socket thing. It goes back in but is loose. I couldn't fix any ties at that end as it turns continuously so I turned the link around and attched some cable ties at other end to hold it in.
