Cluster Gauge problem: 2003 Chevy Silverado 3500 4X4 6.6

[/b]Have filed a Claim # with GM the Dash cluster gauge went out on my 2003 Silverado with only 57000 miles. At least I think that is what the problem is! Have checked all of the fuses, alll good.
Sometimes when I turn the truck on the gauges work other times nothing. Just moved to Fla. And haven't found a new dealer. Is this a problem that anyone else has had? It is hard to drive without knowing how fast you are going or if you have any fuel!
