Fuses protect a car's electrical circuits from being overloaded. If an electrically-powered item, like your power windows, stop working, it could be that the fuse for that circuit as blown. If you replace that fuse and it blows again, there's almost certainly a fault in the wiring or the item concerned.
Fuses are designed to break the circuit at a predetermined current level. This is why each fuse has a number molded into it to indicate its rating. Always use a replacement fuse of the same rating.
The fuse box is usually under a cover near the glovebox or instrument panel. Sometimes there's one under the hood in the engine compartment as well. Check your owner's manual or your Haynes Repair Manual for the exact location. The fuse box lid will identify the circuit fuses so you can go directly to the one you need.
To remove a fuse, simply pull it straight out from the panel. Often, the fuse box will include a small tool which you can use to remove/install the fuses. If not, use your fingers or tweezers to grasp the fuse and pull it out.
A blown fuse is easily recognized by the melted wire in the middle. If it is blown, push in a new fuse of the same color and rating. Extra fuses of various sizes are usually included within the fuse box. If not, purchase replacements at an auto parts store.
