Lincoln Navigator (2003-2006)

Looking for Lincoln Navigator fuse box diagrams? This article covers the second-generation Lincoln Navigator, available from 2003, and includes fuse box diagrams for Lincoln Navigator 2003, 2004, 2005 and 2006, along with details about the location of the fuse panels inside the vehicle and a clear explanation of the assignment of each fuse and relay (fuse layout).

Fuse Box Location

The Power distribution box is located in the passenger compartment under the right-hand side of the footwell.

To remove the trim panel:
Pull the panel toward you, then swing it outward away from the side and remove it.

To reinstall the trim panel:
Align the tabs with the grooves on the panel, then push it back into place until secure.
