1) Disconnect the negative battery terminal
2) Undo the two bolts that hold the fuse box in place and pull it away from the body work
3) Remove the first bolt that faces the center of the car
4) On the opposite side, on the outside of the fusebox, is a plastic flap that has a snap lock - open it - to reveal the second bolt.
5) Undo the second bolt - the old fuse will now pull out
7) Put in the new fuse, do up all the bolts, reconnect the battery, job done
