Question:

I just bought a 2014 Bravo 7x16 enclosed trailer. My vehicle is a 2004 chevy 2500 Silverado truck. All of the lights work on the exterior of the trailer such as tail, turn signal, brake lights. It has 2 factory installed lights on the ceiling inside that do not work. How can I figure out the issue with the lights? Thank you for your help.

Helpful Expert Reply:

The interior lights of your trailer would be powered by the 12 volt accessory circuit on the 7-way of your 2004 Chevy 2500. This would be the pin in the 2:00 position. You can use a circuit tester like part # PTW2993 to test that pin to see if it is active.

Most likely that circuit hasn't been activated under the hood of your truck, or the fuse/relay for that circuit is blown.

Check out the help article that I attached that has a section in it about activating this circuit.
