Hi, I've got a bit of a problem I can't solve. Our Mk1.5 2003 Focus has developed a fault with the front washer jets. The front jets no longer seem to be working, however when you press the button on the end of the stalk the rear jet is squirting instead. The front wipers are still wiping when I try to use washers. When I pull the stalk towards me the rear wiper works on its own as normal. I've tried washing the system through with some screen cleaner and its not made any difference, and I've had the pipe off the front jets to check to see if theyre blocked and no water is coming through. Any ideas whats wrong here!?
