Cluster Lights, it's a head scratcher

[Ronsonet]

Having an issue figuring out why I'm not getting lights on the climate control, radio, and cluster. So far I've changed out the dimmer switch, checked the relay in the aux 2 box, checked the fuses, and verified the voltage coming from the light switch. Anyone have any idea as to what would make all of them go out at the same time?

Just to add, the check engine, air bags ect all work
