dash lights not working
Hi everybody..been a while since ive posted. Lots have been done to my 68 f100 custom cab....but the one thing that still stumps me...is that the dash cluster ligghts still wont work. Ive changed the 3 bulbs..ive replaced all the fuses..i spent 35 dollars on a new switch and everything. My headlights and tailights still work..ive turned the **** a hundred times and jiggled it...but still nothimg! Its driving me crazy! If anybody has some sort of insight...please help. It would be greatly appreciated.

As you have replaced the switch. The next thing I would do is pull a socket loose from the dash or if it's easier (& I think it is)unplug the wire that goes to the heater control light or cigar lighter light (if your truck came with one)and backfeed the wire or the the center in on the socket, once the bulb is removed, if you remove the hole socket, with a hot wire. This will let you know if you have a switch problem or a grounding problem. If none light up you have all bad bulbs (unlikely) or bag ground. If my memory serves me correct the wire is blue with a red stripe. If they light up the switch is still bad.
