Ok
Okay… I’ve lost all my lights. This picture is taken when my key is in acc mode… when I turn the truck, I lose power to the headlight controls, LED dies and no headlights or parking lights. The driving/fog light switch and the back cab light also dead. The dimmer switch DOES work for the dash lights.

Back story… about a month ago, I was towing and I got a trailer wiring fault… never thought of it that much and continued on. About a week ago I realized my parking lamps weren’t working… bulbs were good, all the fuses were good, and I even had a buddy check the BCM for errors with his FORscan. No codes.

So I tried the old school, disconnect battery and let it sit, did that and came back and now I have no headlights in addition to my lack of parking lamps.

Help!
