Fuse box location

Passenger compartment fuse panel / power distribution box

The fuse panel is located under the right-hand side of the instrument panelThe location of the fuses in the passenger compartment: Lincoln Navigator (2003-2006)

To remove the trim panel for access to the fuse box, pull the panel toward you and swing it out away from the side and remove it. To reinstall it, line up the tabs with the grooves on the panel, then push it shut.

To remove the fuse box cover, place a finger behind the PULL tab and your thumb above the PULL tab as shown in the illustration, then pull the cover off. To reinstall the fuse box cover, place the top part of the cover on the fuse panel, then push the bottom part of the cover until you hear it click shut. Gently pull on the cover to make sure it is seated properly.

What a blown fuse looks like?

If the wire is broken, the fuse is blown (but sometimes a fuse can look completely normal and still be blown and in need of replacement).
