Why does wiper fuse keep blowing?

If your wiper fuse keeps blowing, there is either a short or a "dry connection" in your wiring, or the earth/ground wire isn't making a good contact, try getting a wiring schematics/ diagram and check your wires for any sign of shorting out or corrosion damage. Never put in a larger fuse as this will cause your wires to burn and can cause insulation on your wires to melt and possibly cause a fire!

Mice can also get into your car to nest and they could also chew your cables. this happened to my brother.
