Hmmmmm. I know the usual culprits to check. C200 connector behind glove box, but the radio still works, so it isn't that. Fuse looks good. One last place, there's a main connector that bridges the HVAC harness to the dash harness and they're notorious for burning the ground side out of the connector.

Deleted the satanic 1990s GM wiring connector. Resolder, all good!

While I had the ashtray assembly out, I went ahead and deleted the cigarette lighter. Installed a 3.0 Amp USB charger, so my phones will fast charge!
