Hi again, I have a rear door on my 2014 ram 3500 cab and chassis that the dome light and door lock quit working. After reading post from this site about bad wires I pulled the door panel off and started checking for broken wires in the harness between the door and the pillar. I noticed at this time there are speakers in the rear door that don't work, I read that the cab and chassis have them installed but they won't work from the factory. Can anyone confirm that??
