I'm having an issue with my 2016 579. My stock fog lights quit working.
I have located the fuse and replaced it with no success. I have attempted to find the relay and can not seem to locate it. The switch lights up, the headlights are on low beam, and the truck is running. Still no power at the light.
I'm stumped. Any ideas?
