Cluster Dash lights not working trim gauges etc.

[Donnie88]

2004 chevy Tahoe. The normal lights on my dash are working such as blinker, check engine, info center, prnd321. The backlight for Speedo and the ac control are not working. I have checked the fuses they are all fine. I have even replaced the dimmer switch twice just to make sure I didn’t get a faulty one. This has been a headache and a half. If anyone can help me figure this out I would greatly appreciate it.
