I have recently started having this problem as well. I got brand new tires about 3 months ago, no problems until about a month ago. The tires are fine and this problem only happens at 45+, but only once in a while. It's not balance, I've had a variety of balance issues in other vehicles and those are all noticeable and reproducible. This vibration only occurs at speed, not when braking...brakes are fine, no warp, smooth... It definitely does it on road that is really smooth, like fresh paved freeway and new roads. It has me stumped and I don't want to take it to the dealer (2016 still well under 5 year/100K) unless it is wayyy more reproducible.

I am interested in the wiring diagrams but your email address bounced... If you're still active and see this reply, please advise on how to go about getting your diagrams...

I HAVE EXACTLY THE SAME PROBLEM in my BRAND NEW 2016 NV Passenger V8! Just got it a couple days ago, already back in the shop because of this EXACT climate control problem! Excuse the capslock, but I am still hot on this issue! So much that I went to another dealer today to test drive another NV from a different batch to verify whether it was a design issue or a one-off on my van. DESIGN issue. The other dealer NV did the same darn thing. There must be a solution to this... Did anyone here ever get it fixed? If I go from 60-61, ice cold, 62, you can hear the actuator or blend door moving and it starts getting warm, by 70 it is feeling the same as it is supposed to at 90. Can't get it cold until you go to 62 or below. Dealer claims that's just the way it is...
