Just gonna have to check your wiring at the back of your plug. My ford did the same thing everything looked ok but as I dug further there was a broken wire right behind the factory plug

Have you tested each lead at the plug with a test light?

If it's dead at the plug and fuses are all happy, have to start tracing wires back to find a short. With truck off, you can check for continuity across the leads - if you have continuity, there's a short in your wiring somewhere.

Okay thanks well a few days before I had a trailer wiring code come up aswell as my four by four so I went in and thy deleted the codes the four wheel worked and the trailer wiring I thought was my flatbed because it had a broken plug could deleting it have something to do with it!!?

Anything after 1997 should be wired this way. Don't always assume color codes are correct but location is.

My 2011 350 had the same problem. It was a broken wire behind the plug. Sounds like a ford problem but I had to buy a new one

Thanks to everyone who helped me out it was a 25amp fuse under the hood that was poohed and put a new one in and she's working thanks again everyone !!!!
