It's likely been discussed before, but I couldn't find it. My F250 came with a brake controller already installed. (No brand on it). One wire was cut on it...leading me to believe the previous owner had encountered a problem with it. Anywho, I hooked it up the other day in hopes it would work. The LED would go from green to red as brakes were applied, and I could hear a noise from the brakes when Ben pressed the brake pedal. (I assumed they were working). Later that day, I started hearing a hum/buzz from under the dash near the controller. So I disconnected it. I put in a "new" one today that I aquired several years ago from a friend. It's a Tekonsha Envoy. The green LED does not light up when the trailer is plugged up, but red shows when brake is applied. But I can't hear the trailer brakes making any noise, and from what I've read, they are supposed to make a hum/buzz as the brakes activate.
I have checked the plug...all connections are good. Plug grounds good on truck and trailer side. Do I have a bad controller? Or wiring issues? Anyone else have thug sort of trouble?
