Hey everyone,
Newbie here, so please bear with me as I know this has probably been covered somewhere and I am just not seeing it.

I have a 2013 Grand Cherokee Laredo with a low beam headlamp that is not working. Notate - just the left headlamp NOT both low beams.
We have changed the bulb, changed the fuse/relay, checked the wiring as best we can without ripping the entire harness apart, even put an ohm meter on it to make sure it was receiving power.
There was no flickering or warning that something was going. All the interior lights work and there are no other issues or 'quirks' that might suggest the electrical system is having issues.
I have spent 4 days on you tube, reading forums, talking to 'mechanic' friends and am confused as to why just the left side low beam is not working.
So I am putting the front half of my Jeep back together before the rain hits and hoping for some help as to other options to explore.

Literally any help is appreciated.
How do I determine if I am a WK or a WK2 model?
