Question:

Expert Reply:
The right turn signal/brake light not working on a trailer could be the result of a bad ground, broken wire, corroded trailer connector or a blown fuse or relay on the tow vehicle's tow package wiring.
Make sure that the vehicle side and trailer side connectors are clean and free of corrosion inside and out. The main connector grounds should be attached to clean and corrosion free bare metal surfaces.
The light grounds should also be attached to clean and corrosion free bare metal surfaces. If there is anything between a light ground and the metal trailer frame or if the trailer has an aluminum frame, tilt bed, or folding tongue, any of these things can interrupt the ground. Running jumper wires from the light grounds to the main trailer connector ground can help.
Check the wiring for any broken or loose wires and repair as needed. On the tow vehicle you can check the owners manual for the locations of any fuses or relays related to the tow package wiring. I have also included a link to a help article if you need to test the vehicle side connector.
