Oh yeah, I had the same exact problem! Driving and all of a sudden the cluster goes dark & needles lay down, then they click back on, go all the way to the right & then back Left. After I put a new battery in there, it hasn’t happened again. And food for thought, while you’re in the gauge cluster repairing you might as well go ahead & swap out all the stepper motors so everything is new. You can order the stepper motors & LEDs for like &20-$25 from “GM Gauge Repair” (I believe that’s the name it’s been so long ago.” That’s what I did & I’m very happy with the outcome. Regardless, best of luck with everything.
