digitial dash troubles

when i first bought my bird the dash lights didnt come on at all, si u replaced the bulbs at the top of the speedo and voila! they work... until you hit the headlight switch then they get dim. i replaced the headlight switch thinking it was maybe a bad dial on the switch but it's still happening!! any ideas what the problem could be? i would love to get this car on the road but i need this issue fixed before i can. thanks for all the input!

When you say they get dim do you mean they go out so you cant see them at all ?

They are designed so they  dim with the headlights so they are not so harsh on your eyes at night
Fox-less at the moment

There's a cluster illumination relay in behind the center stack (near the radio, on the left hand side, really hard to get at). That went bad on my old 88 Cougar and it was doing the exact same thing...

Do you have an aftermarket stereo installed?

You might check this article for some useful info  http://www.coolcats.net/tech/troubleshooting/dash.html

I know waaaaaaay back in the day, I put an aftermarket stereo in my car and my speedometer worked fine until the headlights were turned on.  Then you could only see it with a flashlight.  I don't remember exactly how I fixed it, but I think the article will give you a good starting place.

When anything electrical happens to our cars usually the first thing to do is have a peek in the fusebox.........lesson learned lol
