I would suggest you try a more tech oriented forum than this one. Sometimes some people will have a good nugget of advice for repairs, but mostly we just bitch and moan about the auto industry. There are several for the GM Trucks. The only one I can name is
www.GMFullSize.com.
I know there has been problems with the gauge clusters in the GM trucks, but I don't know if the known problems go as far back as '94 or if they extend to the 3500 series, but they're likely the same cluster as the 1500s I would think.
Best of luck.
