Explaining the location of a specific fuse is difficult without an image of the fuse panel layout. So...
The following is a link to the fourth portion of the 2004 Lincoln Navigator Owner's Guide (pdf):

The "Fuse and Relays" section begins on page 279. Pages 324-331 contain a diagram illustrating a fuse's location, description, and amp rating.

Hope I was helpful!
The "clock spring" is broken would be my guess.
Look in the owners manual. There is a fuse. In the fuse box low on the dash to the left of steering coluum.
On our 2000 Navigator, it's under the driver's side dash under the steering wheel.
Steering controls left and right, suspension controls up and down. Any problem with one will affect the other.
There are a series of wires that run from the steering wheel controls to the radio. An electronic circuit could be used, to combine several controls into fewer wires.
Between your steering wheel and your instrument panel on your steering column, you will find a small rocker switch that controls the parking lights. I can't tell you why it is there, but it does turn the parking lights off and on independent of the ignition and headlight switch.
It doesn't control anything. It is the connection for the cruise switches, horn switch, radio controls(if equipped) and airbag that allow the steering wheel to turn and there to still be a connection.
The steering is what controls the gauge in cruise control. This is in any car or truck.

The fuse that controls the cigarette lighter on a 2004 Saturn Ion is a 20 Amp. fuse located in the bottom right corner of the fuse box. The fuse box is located just to the left of the steering wheel in the dashboard under the instrument panel.
It controls the variable power steering on your vehicle. The faster the car goes the less power steering the vehicle needs. The module is what controls that. It senses the cars speed and then determines how much power steering "power" needs to be applied.
The cruise and radio switches do not share a common fuse.
