since i've recently put the battery into my car, i've been checking for lights and whatnot to be working. However the lights inside the instrument panel will not come on, same with the heater bezel illumination.
The clock works, the map light works, dome light works, ignition switch light works, but the instrument panel & heater bezel lights do not. I replaced the fuse that runs the bulbs in the fuse box, but that didnt solve my problem.
since there are so many bulbs inside the instrument panel, i find it hard to believe that they are all burnt out, so i'm thinkng that i'm missing a ground somewhere. I have a wiring schematic, and I see two grounds, one on the actual instrument panel, and then one off of the plug that goes into the panel itself, but as far as I can tell that is grounded...
Since all 69's had the same dash, only difference being Tach Dash or not I would guess he's talking about his Mustang. This is a Mustang related post, that's why your having trouble Glen.
With my 70 I know that when I pull my headlight switch on and it doesn't sit in the exact right position my dash lights don't light up. Just a little wiggle/repositioning of the switch and on they come. Might check there and see if your not having the same problem with the contact in your switch, yours may not be making contact at all. Just a thought.
I have to say I have a bit of the same attitude as Glen here, we have a whole bunch of newbies and for some unknown reason they refuse to fill out any information and think we are able to read minds ! It sure would be a little helpfull if they would all give us a little more info.

The dash and heater lights are on a rheostat that is part of the headlight switch. To win the Doofus award you would have to have the lights dimmed all the way down and not know that this is your problem. I'm sure you know about the dimmer and that you will not win the award.
It is possible that there is corosion on the contacts or that the rheostat is bad. You will have to take the headlight switch out to test it. To remove it you will have to first take out the knob. This is done by holding done the button on the side of the switch, under the dash, and pulling the knob & shaft out. Then you remove the bezel with a big flat blade screw driver. The rheostat portion is
the big spring looking thing on the front.

I would suspect a bad headlight switch as well. The '69 dash has a built in ground (part of the big plug), unlike the previous years that had a seperate wire run from a dash pillar to the CVR mounting bolt.
Do the gauges work? (may be hard to tell if the car isn't yet running). This would tell if the ground is good. If the gauges also don't work, I'd suspect a the ground wire is broken, the plug isn't plugged in well, or there's a problem with the dash circuit board itself.
