Why Arent The Interior Lights On My 2014 ATC Enclosed Trailer Working?
Question:
2014 ATC trailer interior lights don’t work, but the running lights are all working fine. Same pin on the trailer connector to the truck is power for both. So why don’t the interior lights work.

Expert Reply:
If all the other lights on your 2014 ATC enclosed trailer are working when plugged into your truck, you either have a bad ground or a break in the wiring somewhere.
The ground issue will require you to make sure all your grounds are good and solid. I would also make sure they are not "stacked" with other grounds. This is a fairly common practice, but it is always best to have each ground on its own. If all those look good and or it doesn't get everything working, yo do have a break somewhere down the line.
You will need to use something like the # PTW2993 wire tester and follow the wires going to your interior lights to find this break. Once found, it will need to be either repaired or replaced and you will be good to go again.
