How do you you replace a burned out fuse?

First you gotta find 'em.

There seems to be trend with modern autos to hide the fuses in strange and unexpected places, Often you have one box in the cabin and one in the engine compartment. Consult your owners guide or applicable Chilton's reference to find the location. The fuse puller may or may not be easily locatable. There may be a fuse puller in one, but not both, of these locations.

Having found the fuse box you will usually find the description of each fuse on the cover.

There is usually a fuse puller inside the car's fuse box. Take the fuse puller and use it to remove the burned out fuse. Get an identically rated fuse and insert it in the place in the fuse box that you just removed the fuse from.

Note: if the new fuse also burns out there is a more serious problem that must be corrected before replacing the fuse again. Never install a fuse with a higher amperage rating than the original!
