I have a 2004 Suburban 1500 and a couple of days ago all of my dashboard gauges, DIC and information lights suddenly stopped working when I started the truck. I checked the under hood fuse (is there another one to check?) and it is good. When I reinstalled the fuse the gauges and DIC started working again. The next morning when I went to start the truck the same thing happened again: no gauges. Removing and reinstalling the fuse now has no effect. The truck drives fine with no issues; just no gauges or DIC. Where should I start looking for a solution? Thanks. Frank
