I'm new here, so please excuse me if this is old news...

I'm on my second trailer brake controller, and it is failing as did the first one. Does Ford have a fix for this? Is there an after market fix?

On my 2013 F-150, the first TBC locked the brakes and nothing would remedy this. The second TBC now shows "trailer disconnected" on both trailers that I use, even though I've checked all connections and they are solid.

Any suggestions?
