My 2012 F350 cab and chassis doesn’t have any rear blinkers or rear brake lights. Front blinkers and the center brake light on top of the cab DO work, but I have no voltage to the back.
I thought it might be the Body Control Module, but I also don’t have any voltage to the left or right blinker/brake prongs in the trailer plug. The Ford service guy said he didn’t think the trailer brake lights went through the BCM, but it didn’t sound like he knew for certain. Also don’t get any voltage to the electric brake prong when the brake pedal is applied, but I do get voltage when I use the built-in trailer brake controller.
Couldn’t find any blown fuses.
It had incandescent bulbs in it. Some were burned out. No LEDs.
Anyone have any ideas?
