Switch ?

Everything else on switch works. When turned to auto my parking lights do turn on just not my headlights.

Stock headlights. No wiring done. And still work in manual.

I would try a new switch

I have the somewhat the same issue, except when the switch is set to auto, my headlights are always on. Ford recommended checking fuses

Any idea of a fuse number?

F36 is what they told me

F36 is actually for the trailer stop and turn signal. Would driving running lights (DRL) be a cause for this? It makes sence auto lights and DRL kinda same thing right?
