trailer lights not working and cant figure out why
so I have an enclosed trailer and the stop and turn signals to not come on, but the park light do work, meaning that when i tturn the lights on thetrailer ligts do light up but i get no turn signal and no brake light,
i have baught new lights and wire and made sure I have a good ground and same thing happers,
so its got to be the truck, and how could this be its only got 2000 miles on it, not old enough for corrosion,
Help me help me, does anyone know what I can try next??

do your trailer lights require the constant power wire to be on? I bought a lightbar that does and it didnt work either. there is a fuse and a relay in a bag in your door or glovebox that need to be installed in the fusebox, not sure why they werent installed from factory. sadly i dont remember where they go, but if you look in your manual it will be concerning the constant power wire in the round trailer connector. There should be one fuse and one relay. they go on the right side somewehre near the back of the fusebox if you are standing in front of the truck looking at it under the hood.

All you need to do to test with the test light is turn the hazards on and the parking lights on. The turn signals for each side is the same circuit as brake lights. Don't need someone to step on the brakes this way.

Like kmac mentioned, you likely need to put the additional relay and fuse located in the glove box into the main fuse box under the hood. Without it you are only running on the four pins which does not provide the turn signals. My truck was the same, once I put the relay and fuse in all was good. For some reason, these two items were not installed at the factory but were included with the truck.
