Dash cluster won't light!
Hi Y'all!
New around here so forgive my "oohs! and ahh's! and wuzzats?" Lol!
I just picked up an old farm truck from a friend of my dads....a 1973 F100 with 167k original miles on it. Since it was a farm truck, in Arizona, with dust and dirt in every nook and cranny, not much was done to stuff that really didn't matter...like the dash cluster lights. Darned things won't go on no matter how many wires I check or how many lights and fuses I change. My guess is just give it up while I'm behind and get a new cluster, but being incredibly stubborn, I figured I see what y'all think I should do next.
There's other things that I have to do to it, like replace the starter and the a/c, but right now the bloody dashlights are bugging the daylights out of me. Praise God for a magnetic led flashlight that I pop onto my steering column when I drive at night, at least I'm able to stay within the speed limits that way!
Thanks in advance for your input!

I had read that somewhere but I couldn't remember where or when I read it. For all I know it was on this forum! I will check that out when it stops raining here, lol!
Have a great upcoming weekend!

Mine don't light either, except the right turn signal is constantly on which I found out by reading here is indicative of a bad socket on the front turn signal itself. Let us know if yours turns out to be the headlight switch.

You said Arizona farm truck? Dust is conductive. (believe it or not) Check to make sure you have power on the output of the headlight switch. If you do, VERY CAREFULLY take the printed circuit board off the back of the gauge cluster and gently clean it with water. Allow it to dry completely and reassemble it. We had similar issues in Iraq on the LMTV's with the dust. A lot of strange problems were cured by cleaning the systems. (with compressed air on real circuit boards) The circuit pad on the back of the gauge cluster is just really flat copper wire. Also, clean the sockets with a wire brush and bend the tabs down a little to make the connection a little stronger. I bet they work.
