Have a 2004 F150 Heritage 4.2 V6. My odometer does work, but the light goes on and off. If it is working when I start to drive, if may or may not be working when I arrive. I can sometimes hit the dash on top and it will come on, but not stay on. Help me out with a fix, because I am self employed and I have to right my mileage down. Thanks the lawnmower man

 

There Is a how to on fixing this somewhere on the forum .

 

I made a how to, just look up the threads I started on my profile
