It sounds like water is getting in somewhere creating a short. Since it happens when the trailer is not connected, I would check the cover for the 7-Way and see it closes all the way. If not, that is probably what is letting the water in.
You can also check the harness and connectors behind the 7-Way to see if they are cracked or chipped. If so, clean them and make sure you use some dielectric grease, like part # 11755, in the connectors to help keep water out.
