My '12 3500 with just a tick over 80k recently developed a random flickering of the backlighting for both the voltage and temperature gauges. While either/both are flickering, I've tried to adjust the brightness to get it stop, but no luck. All other interior lighting seems to function normally, and the gauges still work, but it drives me crazy... Anyone seen this before or have any clues on how to fix it? I've checked the gauge cluster lighting fuse and it checked out just fine and was fully seated, so that's already off the list??

I would almost guess a bad ground on those two bulbs. If it was all of them flickering I would include voltage regulator in my suspicions. Just my thinking off the top of my head.

Unfortunately no bulbs, at least not serviceable ones. Near as I can tell it's a sealed, packaged circuit board setup... But I appreciate the response nonetheless.
