Speedo not showing speed

January 11, 2011, 08:33:49 PM

I have the regular speedo and today i get into the car and see that the speed is not showing up no numbers/letters anything. The cluster and everything lights up but i can't see the numbers. Any fuses i should check? something with the harness?

Like, you can see the green light behind where the numbers show up, or is that part just dark?

If you shine a flashlight to the speedo can you see the numbers?

This happened to me a while back. I burnt out a fuse. I didn't think it could be, I looked through the manual for a fuse layout and certain things that the book said were on the circuit still worked. It'd pull the fuses just to see. I know that's what it turned out to be. I want to say my four way blinkers still worked, I could be wrong, It was a while back. I see your car is a Lincoln, but they are probably similar.

the center of the cluster where the top steering cover comes in contact with a very fragile ribbon / flex print harness.
when that part is intermittant or the runs on that section are broken, it can lead to having a completely good back light situation but no LCD display of numbers.

I suspect the steering column cover has been off before. "correct"????????

Be honest, it helps to have the background.
Did this suddenly start happening or what?

Its pretty impossible to damage this flex print unless there is several assembly / disassembly tasks in the past.

I broke mine when I did the 199mph speedo mod to the speedo module so, I cut the flex print straight across where a couple of the silver solder runs was cracked and soldered 24awg wire across each path.

still works great plus it "hardened" that area of concern.

let us know.
