I checked everything,.. The cluster is gonna come out next.
I don't know if any of you remember, my whole inside burnt up a few years back.
(I posted pics). Insurance totaled the poor truck. And I bought it back. I the found a complete interior,
same color, same year much better shape.
I replaced everything,........... Minus the friggin cluster. That's gotta be the problem.
It's just a little strange four years later it's showing problems... Bummed.

 

i believe soot degrades wiring over time. maybe it's just now catching up with you.
