There are several things that could cause the dash lights to not work in a 2004 Lincoln Navigator. The first thing that comes to mind is a blown fuse. The fuse box is located on the passenger side footwell area below the glove box. Pull the cover off and the fuse You're looking for is in the bottom row the closest to the firewall, not the one that sits horizontally but the first one is vertical. When You pull it out hold it up to the light and make sure that the filament inside is intact. If it is blown, replace with a flat blade style fuse with a 10-amp rating. If the fuse is good You probably have a wiring issue.

If the instrument cluster on the 2004 lincoln navigator is not working then you likely have a bad ground, or the wires have shorted somewhere.
