Ok, my interior lights are out. No dome light when you open the door. If close the door and hit the overhead dome light switches in the roof, no lights. If you hit the outside cargo light, it does not come on either. I also have no power to my brown wire running to my trailer that runs the taillights.

All fuses are intact.

I do have all blinker and tailights running on the truck.

The brown and green blinker wires to the trailer does work.

The electronic brake blue wire also works to the trailer.

What is going on here? Im a little baffled.
