so on the altezza, there is 3 fuse boxes, 1 in the engine bay, one in the drivers side footwell to the right of the pedals nearest the door and one on the passengers side foot well, closest side to door too. little panels pop off and on the back of them should be diagrams showing you what each fuse is for. The fuses are mini blade fuses and can be gotten from any motor factors. get a few though incase it pops again, 7.5, 10 and 15amp are the most common ones, you might find a few spare ones in the fuse box under the bonnet
