What to do if your trailer turn signal is not correct?
If you still have the problem, disconnect the trailer to test the 4-Way on the vehicle using a circuit tester like # 40376. First, test the wiring going into the convert box on # 118426 from the vehicle tail light wiring. If the signals are not correct then you have a problem with the vehicle wiring.
How are brake and turn signals combined on a trailer?
The brake and turn signals are combined on a trailer, so it would be odd if it was just the brake light giving you issues. Either way, I would check to make sure the ground on the light assembly itself is securely attached to a clean, bare metal surface – whether it ground through a dedicated wire or through its mounting hardware.
