ok  got out of 2011 2500 diesel locked the doors and walked away. looked over at truck half hour later back of cab light was on went over doors unlocked and windows  are down. had key fob in pocket but did not touch any buttons on it, door locks only button on it. closed windows, manually locked doors and walked away again looked back a while later same thing again. left key fob in house has been alright sense then . any ideas whats going on?

Maybe a short in the wiring between the lock and window?  One touch down. Would make that easy to happen.
