Maybe I should post in the towing forum, but I thought I may get a faster response here. I have an 08 c&c drawtite brake controler. Brakes stopped working all of a sudden. check everything and can't find a problem. brake lights work, blinkers work, only the brakes don't work. went under the dash and checked the blue wire from the controller and no power, can the controller be bad. how can I check to see if the controller is bad?
