(2.0L S-Max 07 plate).The same problem occurred yesterday. I was travelling home from work and the windscreen wipers came on on full power for no reason and then stopped. This happened for twenty miles intermittently . No matter what position I pushed the stalk they would not stop. Once home and the doors locked the alarm went off and then stopped. Bizarre before I go down the route of frustrating visits to my local Ford garage any advice?
