Orlandotommy- mine is the button to the left of the headlight knob inside the truck. I pushed the button to the left of the headlight knob and my bed lights came on. I bet yours is where mine is. They are identical trucks lol.
Mine is in the same location, interior and the exterior bed switch. The bed lights do not come on until the truck is stopped. I also tried my mirror light buttons and they don’t work while driving either.
