dome & sun visor lights not working

[dpounders]

All of my dome / reading lights don't work when the doors are shut. The dome / reading lights come on when you open the door. I looked at the wiring & it has three wires. I am assuming that one is a ground, the other is 12v supplied when the door opens (which I tested fine), and the other should be a constant 12v (which I tested bad). I checked all fuses and they are fine. I also changed the relay. My conclusion is that there is a burnt or disconnected wire somewhere but I'm not sure which way the wires run so I don't know where to start.

Yes. It works fine.

Found the problem. The supply wire located in the side floor channel on the passenger side was burnt out along with several other wires. I spliced the wire back together and everything started working.
