Hey guys.
Im having problems with my 2005 gmc sierra 2500. When i hook up any trailer my brake control recognizes that there is a trailer connected. If i hit the manual brake button on the controller it actuates the trailer brakes. But if i hit the brake pedal nothing happens. As well if i put my four ways on only one side of the right side of the trailer lights up.
Ive tested my truck on multiple trailers and its the same problem with every trailer so it has to be my truck.
Any idea whats wrong?
