Hi. If there is no power at the trailer plug, then that is usually a sign of a blown fuse. There is also an electrical junction block near the rear bumper that can fail, but that usually also causes other exterior lighting problems. A mechanic would first check the fuse. If it is blown then the system would need to be inspected for a short. Most of the time on the trailer plug the short is the trailer itself. In most cases the trailer would then need to be hooked up to see if the fuse blows again. If you need further assistance, I recommend you have a mechanic, like one from YourMechanic, replace the blown fuses and inspect for other problems.
