2018 JLU w factory LED. Wife's vehicle and recently replaced the main battery and disconnected the ESS battery via F42 pull and neg cable removal as well as hood pin removal. Not related I am sure, but noticed the fog lights were not functioning. Is it possible that these have both burned out over time? Wouldn't be surprised if they were left on at all time. :giggle:
The green fog light "on/off" illuminates on the dash.
Is there a process or checklist ? I'm assuming the 2 fuses in the under hood panel, but anywhere else to look/check/verify before i test for 12.5v at the bulb behind the inner shield?
TIA,

Bumping this to the top as I now have replaced both fuses 26 and 29 and still nothing. New Lights installed as well.
Is there a 3rd fuse or location to be looking for?
The green light does illuminate when the center headlamp button is depressed and will function on/off when the high beams come on. It's as if there is another fuse I am missing..

Hey friend, have you found a fix? It sounds like you might be having the same issue as me. I have a 2018 JL Rubicon that did not have factory LEDs, but I had the codes changed by my friend at the Dealership to make them work 😉. Both of mine stopped working just about a year ago now, and I can't seem to figure out why.

I checked the fuses, they were fine. I checked for voltage at the fog lights, and both are showing 12V. I even snagged a new set online, and plugged them in, and they don't work... Could all be a coincidence, but I'm stumped.
