My dad has had problems with his tdci o7 galaxy were the lights and window wipers just come on for no reason and will not turn off. I think on his car it is a problem ford are aware of and he had it done under recall. I will be seeing him later and will ask him if he knows what they did to fix it. I know it is a different car but it may give you somethink to go on as it sounds like the same problem.
