For the factory trailer wiring the only thing you can really check is fuses and connections for the wiring. The trailer wiring will have separate fuses for your trailer brake and turn signal wiring. You can check your owners manual for these fuses. There is also the chance of a loose connector but since your running lights are working it is a slim chance of that.
