Trying to figure out why my overhead and courtesy lights will not come on. I've replaced both door switches and the headlight/dome light cluster in the dash with ac delco parts. I can manually turn the interior lights on with the dimmer but cannot get them to come on when opening doors. My guess is its one of the barn door switches in the back. Any advice is appreciated thanks again.

The override button isn’t on is it?

Cargo door switch would be a good guess.

I have tried the override button and the dimmer wheel. Haven't been able to find the defog contacts for the barn doors online which I'm guessing uses one of the pins as the door switch.

Thanks for the help. I'll try to locate the parts online again. If it doesn't work that's just one more thing i can check off as the culprit.
