I'm willing to bet the HVAC issues are software related. It's been 20* here in Dallas and I've noticed that if I have the dial cranked all the way to max temps, air direction blowing forward, I get the weird whistling/whining issue from the passenger side blower motor BUT only when the vehicle is cold. My fix is just switching the air to "circulate" and you'll hear a noise that sounds like something in the dash is opening/closing and then I get crazy hot air. Had to adjust the dial to cold air after about 10 min because the car interior was uncomfortably warm.
I also have the magnetic owl seals for the safari windows which I'm sure help keep some of the heat in the vehicle.

We get it, your trucks are perfect. Why do you continually have to argue with people who are telling you they are having problems? Mine is either Hot!! Or Cold. The rear vents are hot when in cool, left to right isn’t even. Why is it that because dual Brent thinks his are perfect you keep demanding people explain themselves to you bud. Why can’t you accept these trucks have issues.
