The Rear Windscreen wiper is stuck upright and not working.
I have changed the fuse, so it's not that.
No warning lights on dash.
I think I hear a motor whirring when I try to start it.
So how do I work out what needs fixing - trying to avoid having 2-3 costs - one for diagnosis, one for part and one for the fix..
