Nasty Buffeting
Have a 2015 WK2 that has always had bad buffeting. If any one window is open, even partially, the buffeting is bad. Open a second window on the other side and it`s ear drum pounding horrible. Open a second window on the same side, it goes away. Just dawned on me to ask if anyone here has the same issue and possibly a reason/solution? Appears this cockpit is sealed tight.

I think it is caused by this type of interaction:
https://en.wikipedia.org/wiki/K%C3%A..._vortex_street
The PT Cruiser had a similar problem near the rear of the top of the vehicle. Later they added a spoiler to try and reduce it.
By messing with the air flow patterns by moving windows up and down you are likely disrupting the formation of the pressure waves (wherever they are forming).
It can be hard to know exactly where it is forming, and whether anything simple can be done to permanently disrupt it. Looking for DIY stories from others might help, perhaps not. Things like roof racks, rain guards, light bars, or sun roof air dams might help to break up the flow. But it would be hard to know without actually trying them.
Do you have a sun roof? A quick search seems to point to that as a likely source of the buffeting problem on the GC of your era.
