Thanks Ron, all stepper motors changed out a couple of years back, gauge cluster just fine.
New oil pressure sensor in, all seems OK now...
Very common problem it seems, O'rielly tech says 12 sold this year alone in their small town store.
Temp gauge problem could very well be caused by oil...
Help please? 2005 Tahoe Z71 2WD 5.3L
While driving to day I noticed Oil Pressure went from 45 PSI normal to 60 PSI and then to 80 PSI!!
Shortly after that, Temp gauge went to bottom of scale.
Disconnected battery and on start up, Oil gauge showed 60 PSI whit out engine having cranked yet...
Welcome.
Another point you may want to consider. 200,000 miles on mine.
Oil pan gasket was leaking and oil pressure had dropped to between 30 to 35 lbs at highway speed just lately (Common Problem).
Pulled oil pan to change out the gasket and put a new o-ring on oil pickup tube.
No more oil...

No, mine's a 2005 Z71 2WD package. Only year they made those. 200,000 miles and still going strong. Preventive maintenance is the key.
Roof rack lights were a mod I did using halogen lights I got off Ebay. Hooked them up to the trailer hitch wiring harness with a switch under dash also for...
You may want to look into the rook rack backup lights.
And, I shipped my cluster off to have a Trans Temp gauge put in the left hand blank hole. You cannot see that data any where. $80 I believe, cluster has to have programming to allow the gauge to work. Sender already in the tranny.
Low coolant problem.
Run your fingers around the heater core connections on the firewall. That's where my 05 Tahoe was slowly leaking.
Replacements for those are readily available ay O'rielly's.
