There is an interior light override switch on the cluster dimmer switch please make sure that is not activated. Also, there are three other switch it can be, cargo, rear interior and central interior switches, please check all of those as well. Plug the BCM back in, it could be the PLG control module but lets do one step at a time. Ken

It ended up being the Bcm. Removed the Bcm from the vehicle and took it apart. Found burnt connections on the bcm circuit board at the door switch connector. Looks to be possible water intrusion
