The first thing I would check is that the grounds for each of the lights and the trailer connectors are secured to a clean bare metal surface. Once this is done you will then want to check for corrosion on each of the trailer connectors. If there is corrosion present, then you will want to spray them down with some electrical contact cleaner and apply some dielectric grease like part # 11755.

If neither the grounds nor trailer connectors seem to fix the problem, you will then need to begin tracing the right turn signal wire (usually green) while checking for shorts. You can use a circuit tester like part # PTW2993 and test the pins on the trailer connector to see if the problem is on tow vehicle or trailer.

I have attached our wiring help article for you as well.
