I purchaced your brake controller at NAPA #755-2281 on 7/21/11 had it installed and pulled a 24ft trailer with a race car in it many times, it worked flawlessly.. I also have a smaller car/farm tractor trailer that I towed many times with no problems.. last week I hooked it up and tested it as I always do and the brakes locked up and would not release.... I pulled the trailer wheels and checked brakes every thing was good and the wheels turned freely.. I reconnected the electric brakes and the locked the brakes and would not release.... I hooked the trailer to my other truck a F250 with a different brake controller and everything worked fine.. Is there some wat I can reset the controller so it will work properly like it used to....
