Dome lights/radio/4WD orange light and more unexpectedly turned off

Some of my interior lights in my gmc Yukon 2012 not working anymore and I don’t know what happened can anyone explain to me that?

the visor lights do not come on until you flip the mirror lid open, but the rest appear to simply be burnt out.

Yup I know but still not working even when I open it

the visor bulbs can be replaced pretty easily, the other lights are a bit more difficult, the headlight & 4wd switch can be replaced with new switches or the lights inside are very small and can be replaced but this requires disassembly and soldering. same for the radio and the lower switch bank

It looks like the button/stalk that controls the brightness of interior light is in the out or adjust position. Is it possible you turned the brightness all the way down?

Nope I am pretty sure that it’s all the way up

I didn’t check the fuse box, tomorrow I will.
Do you think they have any connection with burned fuses?

Odd, I wonder if all the lamps that are out are not the ones on the dimming circuit. Hopefully it’s an easy fix. Thanks for adding the pics for clarity.

If there is a accessory fuse burnt then "maybe" but doubtful could be the dimming switch -maybe, really hard to say if the fuses are all good try a new light switch

Some dimmer lights work? (Light switch, 4wd, HVAC) but not radio or multifunction switch?
I would check the connectors on the MBEC..

The automatic HVAC controls it's own dimmer, gmlan must tell it what brightness setting it should be.
The diagram above shows the Manual hvac connected to the same circuit, but yours is auto.



I'm not sure which plug that is.. Might try and jiggle them, expecially any plug that has a yellow wire..
