Mine was emanating from the left of the dash cluster to the left ac duct. Somehow it seemed lower than the windshield dash junction.
Youtube search 2014 jeep dash rattle, or something close to that, and you'll get to listen to a couple of more vids. One is clearly a plastic "clunking sound", due to a loose dash I believe. Other sounds form heater core hoses contacting firewall sheet metal are evidently out there too.
If you pull back the connector in the pic I posted, and let it snap back, you can clearly reproduce a "buzz" or more of a "higher frequency" noise, which turned out to be my problem.
I don't know if mine was just due to individual build "variance", or just a poor placement of the connector in general.
