Problem Description and Possible Solution
The speedometer or other instrument panel gauge may begin to work erratically at times. Our technicians tell us that the instrument cluster must be sent to a repair facility to correct this fault. The warranty has been extended on some of these units to 7 years or 70,000 miles.
Average mileage: 109,543 (13,200–306,007)

I bought this truck used a couple of years ago and 3 or 4 times all of the gauges and the tach and speedometer have died for a few days. So far they have started working again before I have figured out what the problem was. If anyone has a solution I would love to hear it.
the whole dash instrument panel is out ..I have to guess at everything.
vehicle will turn on but the gauges wont work
speedo bounces around or dies completely then works later
The radio and the all gauges in the cluster cut out and the gauges bounce. To me it seems like an electrical problem but not sure.
About two weeks after we bought the truck our oil gauge started acting up. We had it replaced and it worked for about 2 weeks and went bad again. GMC wouldn't replace it, neither would the dealer we bought it from. Now 16 months after we purchased the truck the oil gauge is reading off, the battery gauge is reading off, the speedometer has stopped working right in the past week and I'm not sure about my gas gauge but suspect it's off also. You can tell because they always read something different. Will have to get it replaced at a huge cost to us.
Not fixed yet. All gauges just stop working simultaneously. They will all come back to life after tapping on the top of the dash directly above the instrument cluster. So far that works
FOUND A FIX. I have had the same problem. I had 3 or 4 gauges go bad on me. Oil said 0 psi while the truck was running, speedo said 80mph while i was in park and so on. It turns out that these clusters (GMC, CHEVY, etc.) are completely electronic. They use motors for the gauges. Something called stepper motors to be exact. There's 2 semi-easy fixes. If you're handy with a soldering iron, for about $50 bucks on ebay you can buy a kit that includes all new stepper motors and do it yourself. The other option is around $70 where you take out your cluster and ship it to someone who does repairs. Look up speedo cluster repair on ebay. Its about a 1 week turn around. I used someone called mandigital on ebay and i'm very happy.
All Dashboard functions gone. Hasn't been repaired yet.
The oil gauge will stop working now and then and wont read the actually pressure. Now its the water temp gauge is reading off the gauge. It is just wrapping its self around and working its way back to normal.
Started with the speedometer then the tachometer. From time to time oil and water temp gauge will not work
All lights and gauges just work when they wanna
All gauges do not work. Odometer and shift indicator also not working. Turn signals and idiot lights all work. Dealer says might be instrument cluster or ignition switch. Appointment for repair made.
Dash stops working. Will began again when I move the electric window switches up and down.
I bought this truck brand new and it did great until it hit around 100,000 then the speed o meter started acting up and finally quit working. Now the battery gauge and the oil pressure gauge is messed up. Sometimes they will work and sometimes they will not.
Temperature, fuel level, abs ,security ligrhs on, some times work good, some times dont.
my odometer will stop working every once in a while. I used to be able to get it to start working again by banging on the panel, but that is working less and less as I go. No ideas on how to get it fixed.
Had speedomator fixed 6 years ago on a recall now it burnt out again any ideas why
Speedometer working erratically
