Interior light not working?

We need to start with one of the lights that is not working and trace the power back to see where we have power and when we find it, we know what the issue is. I suspect due to all the lights being off, the body control unit is the issue.

I attached the info needed to do this.

Plus here is a guide that will help explain how to do this testing:
