Windows wipers stopped working

I have a 53 plate Ford focus cmax and whilst driving in the rain the other day the window wipers just stopped working. So when finally got home I changed the fuse and it kept blowing so on the Monday took it to the mechanic and he had it for a week and a half and they are still not fixed. He has checked the motor, wiring, fuse box and they are all fine. Before he had it you could hear the relay clicking when you flicked the switch but now you don't? Any advise would be very grateful.

Find a better mechanic/electrician although goodness knows what the first one has ripped out.
The fact your fuses kept blowing would indicate a short circuit somewhere, may be from a bare wire.
