You'll need to look in your owners manual to find where the fuse box is and the manual should also tell you which fuse number covers which circuit. When you take the cover off the fuse box there is usually a guide to indicate which fuse is which (there can be a lot!) Wipers use a lot of power so will probably be rated at 20amps or more. Make sure you replace it with same rating. Good luck
