I am sure everyone with a Silverado 1500 (279000miles)is seeing your guages start jumping. Mine are to the left so that means a bad ground...I am in the process of tracking it down one ground at a time, I'll report back soon, Now if anyone knows where all of them are , feel free to share...interesting video I did on youtube, biglon74 "knock knock" very surorising what I found

I'd agree since they're bouncing to the left (off) that it would be the common instrument cluster ground or the common power supply, rather than the individual stepper motors. Good luck & welcome to the club

Yeah, the gauge clusters have a habit of crapping out:no: My fuel level gauge went like 5,000 miles ago, I just use the trip computer in the meantime until I can get a new cluster.

Power Door Locks jumping ,
Found Problem !!!!!!!!!!! :great:
While Cleaning the Engine Compartment with the Engine Running , I saw a PUFF OF SMOKE COME OUT FROM UNDER THE FUSE BOX !!!!!!!!!
Starting at the Battery, Checking for loose Conections, Batt. Connections -ok , Grounds -ok, Power Wire to Master Fuse on Firewall - ok ,
Power Wire to fuse box ---- OH, ----

Shut off Engine , Disconnect Battery, Unlock fuse box from bottom Half, """"" BINGO """""" MAIN Power wire Connector TO FUSE BOX - Half way BURNED OFF , Bottom Side
