My wife’s truck is a 2001 Chevy Silverado and the gauges lights don’t work. The odom screen and the message screen works, the warning light, bright lights, and turn indicators all work. Just the back lights I guess and the needle lights don't. I thought it might be a ground but everything is tight. Any suggestions?

 

Check all the marker lights, usually the marker and dash lights are on the same circuit so you may have a blown fuse.

 

cluster bulbs are easy to replace.
