The issue is on the truck side of the wiring and not your trailer. Most likely the problem is something simple like corrosion on the pins of the trailer connector as that's the most common reason for trailer lighting issues. Take some sandpaper to the pins of the connector.

I also attached a help article on trailer wiring for you to check out as well.
