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.

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.
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 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.

When you start the vehicle the gauges all fire up and then go to nothing, most generally this will stop when the vehicle warms up but some times even happens when vehicle is warm and will happen while driving down the road. Even GMC dealer can't figure it out.

At 60,000 miles the RPM quit working. Since everything else was fine I ignored it. Then at 70,000 miles the temperature gauge and battery gauge worked sometimes and then finally quit working. I took to GMC and they quoted me $800-$1,000 to replace. I went online to see if other owners had the same problem and found recalls for my vehicle. I went through all my service records and I am so disappointed to find out that GMC service never recommended these recalls be repaired? I feel I should have been advised by service since I am NOT the expert. Now I found out that the part that is broken was covered under an extended warranty of 7 years or 70,000 miles. Since my truck has obviously been so well maintained through GMC Service Department shouldn't that electronic issue been addressed with me? I am a senior on fixed income and these is a major expense. Additionally, my daughter informed me that her 2005 GMC Denali had the dashboard electronics go out completely at 10,000 miles. GMC replaced it 2 times and it still never worked correctly..... She could not tell what gear she was in after two new dash board replacements. It's a shame that such a great vehicle is blemished by something that could have been fixed for so much less money than out of warranty repair costs.
