You need to take it to an Auto Electrician, mine have stopped on my Mondeo and it keeps blowing the Fuse so maybe you have a similar problem. Mine's is in the Garage now being checked out, it's either gonna be the Wiper Motor or could even be the Wiper Switch arm so unless you know what you're doing with car electrics to find the fault i'd say take it to get the problem found by an auto electrician
