Failing trailer brake controller
 

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?
