Try Fuse 15 which is a 10 AMP mini blade. The wiper fuse arrangement is quite strange, as there are three fuses in the complete circuit. It always seems to be Fuse 15 that blows though. A little tip. Always defrost and pull wiper blades away from the windscreen before using wipers. If blades are stuck to the screen the fuse will blow quickly. Screenwash needs to be about 50 50 mix in cold weather. If all fuses are OK and wipers still wont work, the bonnet switch could be faulty.
