Instrument cluster problems.

Just out of the blue my dash lights are acting up. Both of my blinkers are lit up continuously and my fuel, oil and temp guages all go way over to the right. And the lights dim just a tad. It does this intermittently. It will be fine for a bit and then do this. Not sure where to start looking.

Maybe a ground problem ?

What year is your truck ? the later models have a printed circuit panel that can cause issues.

It's a 67.
