2013 T660 Bunk light wiring burning

I have a 2013 T660. I turned the bunk light on from the drivers switch, and it came on at about half brightness. Very shortly I smelled wires burning, and shut it off. After that it wouldn't turn on again. I disconnected the switch at the drivers knee panel so it wouldn't get turned on again there. I tried the switch from the sleeper, and it didn't work there, but I expected that... I can't find any burned wires behind the dash, and I would like to fix the light. Has anyone else had this problem and fixed it, or is there any known problem areas where the wires short out? Or is there an easy way to rewire the light? Even if it is just from the sleeper switch? TIA
