Summary
Some 2017 super duty vehicles built on or before 05-dec-2016 may exhibit inoperative interior lamps, moonroof and/or sunshade with no diagnostic trouble code (dtc) being present in the body control module (bcm).

Before attempting diagnosis or repairs, inspect the sun visor mount area for pinched wiring.
