Hi, my instrument lights stopped working. They will come on when I rotate
the dimmer switch all the way up until the dome light comes on. I have
checked all the fuses but they all look good. Thanks for your help! Gene

If you don't know electrical troubleshooting and don't know how to use a
multimeter, then try replacing the dimmer switch.

If that does not work, you would need a factory electrical diagram (in GM
factory service manual set), a multimeter, and be able to follow the
troubleshooting instructions in the manual / be able to understand
electrical diagrams.

Or take it to a GM dealer for service.

I think Bill is on the right track in his suggestion........likely the
dimmer switch. The dash pulls off fairly easily on these models. I used to
have a link for this when I replaced the 4x4 switch on my Avalanche. If
you're not comfortable doing this, like the other guy said.....dealer time.

I got the switch out yesterday, it was easy to remove. I will try to get a
used replacement and see if that helps. Thanks, Gene
