Hi, just joined the forum yesterday. I have a 2004 2.0D Signum Elegance and wonder if anyone else has had any problems with their wiper controls. car has rain sensors and some times the intermitant setting works as normal and other times the wipers will come on and keep going even if it stops raining and then the wipers will stop randomly half way across the screen at some point. When this happens the washer control for the front screen also stops working. It can go for days like this then seems to clear itself and works as it should. I can get a replacement wiper control stalk for the steering column but don't know for certain if this is the cause of the problem. Can anyone advise?
