I can't see the back side of the cig/usb panel from the pass through as it is boxed in. Ideas on how to trouble shoot this?

It may be normal for those USB ports to work on 110.
However, the cigarette/power port should work. Do you have an inverter on that rig? Usually the power ports are installed near the bed to power a CPAP machine overnight. There may be a switch somewhere to connect it directly to the battery.
Are you the original owner?
