I just picked up an 01 F150 2wd for my daughter. I've noticed that the light up odometer has no illumination when the headlights are off, and when I turn the headlights on (to illuminate the gauges) I get just the faintest bit of light of the numbers of the odometer. It's so dim that unless it's nearly dark outside you can barely even tell it's lit up. The dimmer dial for the gauges is turned all they way up to max before the dome light comes on.

The LCD display for the odometer wouldn't use a traditional filament style bulb for light, so I'm at a loss right now.

Thoughts?

 

I is a common problem. Cold solder joint on the cluster board. Do a google search.

 

Here's the fix right here
