February 9, 2010My new F-150 has the dash mounted factory installed trailer brake controller that is inoperative. I took it back to the dealership and they installed the relay and fuse that came in the glove box but it still does not work. I have pulled my trailer that has operative brakes (I know because my `07 GMC Yukon pulls it and the brakes work just fine!) Anyone have any experience with this and the fix that needs to be made?
