When its dark enough for the auto lamp to turn on it does, but only the parking lights and fog lights. the head lamps will not. when I flip it over to manually turn them on, they work fine. I have checked the fuses and they are all ok. anyone ever encounter this problem? or does anyone have any other Ideas?

 

Sounds like a bad relay. Look it up in the owner's manual.

 

Are you the original owner of this vehicle? If not, I would suspect that the former owner made a few modifications. Your fog lights were not wired to come on without the headlights, from Ford.

 

If you have autolamp enables(light sw pulled out & turned to far left position) fog lights will turn on. If you have the owners manual check the autolamp section;there are some settings thereII think).

 

I see that your truck is a 2005. Let the dealership worry about it, you should still be under warranty (unless you have over 36k).

 

Ok, The Fogs are wired into the parking lamps not the headlights. I am the original owner. There is no relay or fuse for the auto lamps, I spend all night looking for it. The relay does still click when the fogs and parking lamps click on. The only thing I can think of is the headlight relay.
