The gauge on my instrument panel that shows the battery goes way above charge and rests on the battery symbol on the panel and sometimes it doesn't show any power. My speedometer and odometer have quit working as well. Is this a problem with the instrument panel or the voltage regulator or something totaly diferent.

Have your battery and charging system checked. Make sure they perform a good check of the battery cables too!
This is very common on the 03-06 Silverados. The cause is the motors behind the gauges are failing, they all go out eventually. You can get it repaired here - www.drspeedometer.com and there's a DIY guide here - www.howtorepairmyinstrumentcluster.com

If you haven't gotten this fixed yet I can do it. It takes longer to get the dash out than it does to do the repair. I give a lifetime warranty as well. I'm in Houston
