F-250 Trailer wiring problem - Ford Forums - Mustang Forum, Ford Trucks, Ford Focus and Ford Cars

Hi,
I own a 2004 F-250. It has a factory installed tow package that I use daily.

For some reason I have lost my turn signals and brake lights. The running lights and electric brakes are fine.

I checked the trailer wiring and it is ok. I have no voltage at the pins in the 7 pin plug except for running lights. I even disconnected the 7 pin connector from the truck and checked for voltage there also, there is none.

Is there a fuse or relay or somthing that may send power to this connector?
There are no blown fuses that I can find. The truck's lights, turn signals, brake lamps etc.. seem to be fine. Any help would be greatly appreciated.
Thanks

Dan
