What's the fuse number for the instruments lights and the back light on the 2004 navigator

If the thick black and orange wire does not have battery voltage, there is a fuseable link near the battery or starter that is melted.
Same thing with the smaller orange and lite blue wire.
The smaller wires involve the computer and the instrument panel warning light.

These details will help.

Thanks.

locate the fuse box under driver side instrument panel,use a test light hook clip to ground and probe each side of each fuse test light should light when you touch or probe top both side of fuse test light should light.if one side dont light fuse blowed both sides light fuse good.also use test light see if power at the switch if yes problem in the seat motor lower mechanism.

it should be marked in the fuse box. if it's not there or on the lid call your local parts store and they can tell you free of charge

found this, hope it helps!

does the 3rd brake light in the back window work? check fuses if fuses are OK and the hazard lights work, then the turn signal switch may be bad. I dont know what your sons suburban (trailer?)has to do with your navigator?

If the fuses are good there should be a dial that adjusts the brightness of the dash panel.If this dial doesn't work then the bulbs for the dash panel might be blown out.
