Passenger side trailer lights not working

Hi,

I have a trailer and the passenger side trailer lights do not work. Not the brake, signal, or tail lights. The lights on the truck are fine and i checked the tow tail fuse aswell which is fine. The ground wire is good at both ends. Does anyone have an idea of what it can be?

 

Did you check to see if the trailer light is getting power? LED or halogen bulbs?

 

Yes. As I indicated it’s only the passenger side which is not working. Led.

 

Sounds like someone forgot a grommet on the trailer wire harness for the passenger side and the wire is grounding out. Also, check the trailer plug to make sure that some of the wires did not pull out of the lugs.

 

I did some trouble shooting and it turns out the female pin which plugs into the truck had issues, I’m gonna cut and replace it. Thanks for your help.
