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.

vehicle will turn on but the gauges wont work
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.

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.

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.

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.

Started with the speedometer then the tachometer. From time to time oil and water temp gauge will not work

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

Speedometer does not move till the vehicle is moving 20-35 MPH. Installed a reman unit that was programmed with the correct mileage and VIN. Works good now.
