2006 f350 lighting issue

Have an 06 dually. It has auto headlights and fog lights. The front parking lights quit working. The signals and headlights work fine. The cab markers, mirrors, and tail lights all work fine as well. Checked all the fuses related to, and even tried a new oem replacement switch. Bulbs are also all good. At night, when I unlock the doors, the lights will not come on either. Any ideas?

Anybody have a schematic of the headlamp switch?
