Well the dealership finally figured it out. The issue turned out to be a short to ground on the red and black wires for the drivers side visor. Apparently the wiring harness was rubbing against the body behind the headliner. They had to replace the entire visor. After 5 days it's fixed.

So I couldn't figure it out so it's now day 4 at dealership and they still are not sure what the issue is. The technician thinks its a loose pin on the connector that goes to the BCM. Apparently there has been 10 technical bulletins with this same issue. Crossing fingers they call tomorrow with a positive update.

Thanks. I will give that a try tonight when I get home. I also made an appointment with the dealer for next week since it's still under warranty. Cross fingers its something I am overlooking and an easy fix.

Pushing the interior light button in the upper console does not turn the lights on. That is why I am looking for the fuse that controls that button.

I have a 2019 GMC Denali and all of the interior lights stopped working including the center console light and visor lights. The open door off switch in the upper center console is not ON but he LED when its off does work. Plus nothing happens when I press the on/off light button next to it in the upper center console. I checked all fuses in all three fuse boxes, but I am not sure exactly which fuse controls the interior lighting as the descriptions on the fuse box lids are not all that great. So my question is which fuse/relay controls the interior lighting? I appreciate any help. Thanks.
