Update (sorry no pics) for you all. That "coil whine" sound I've been having that I thought was either my head unit or Bose amp- I found out that the noise goes away when I turn the HVAC off! So I'm hopeful that its just worn bearings in the fan motor. I'm going to get a replacement blower from somewhere. I'd like to get an OEM one but will see. Depends on price I think. Hopefully it will go away once that's replaced.

I would love to add similar LEDs to the grill kinda like the "Raptor style" grills like you see on 4Runners. Kinda like this

My Jeep buddy that kinda prompted this has the same lights but in amber, which he ordered by accident. In the video he sent me, they still are plenty bright and would definitely work in a grille. At ~$10 for a pack of 6-10, why not?

Gotta figure out a way to mount them. The same JB Weld I use after I cut off the intake tube resonators?

Do you have Auto A/C? If so it could be the aspirator in the ceiling above the drivers seat.

Does it change pitch with fan speed and go away completely when you turn the fan off? You just mentioned turning the HVAC off but turning the fan itself off will narrow it down.

Nah i’ve already disabled that thing. Bearings in that fan are destroied.

It does go away when turned off, and doesn’t change pitch so much as it just makes a slightly different pattern of noises at different speeds
