I have a 71 c-10 LWB and half my dash lights work and the other side doesn't work. The speedo and amp and water temp gauge lights work have replaced all the bulbs any advice welcome

Your printed circuit. Replacing the bulbs, the circuit area surrounding the designated holes are very fragile (especially 40 years later).

That's gotta be, I don't think the cluster works off of two fuse spots.

What I had to do is spread the little pins apart on the bulbs and clean the socket connections. I also use a continuity meter to check the circuits. I only know of 1 fuse that is used for the dash lights...

Ok Thanks for the Help I will probably be better off to replace the whole thing

You probably just need a dash printed circuit. They run 30-50bucks depending on where you get it...my.02
