New Wagoneer AC problem

[Mr&MrsSmith]

My dad picked up his shiny new Wagoneer a few weeks ago, the weather where we come from is crazy, so he finally went to crank up the AC for the first time...and nothing! Here's the kicker: the temperature buttons only go down, not up. He figured he'd wait until the first oil change to mention the funky buttons, but a non-functioning AC is a whole new level of concern for me. He gave me a call and told me about it and is asking for tips. Anyone else having these climate control issues in their new Wagoneers? Should he head straight to the dealer or is there a simple fix for it?

I had that problem as well wherein the air turns on and off intermittently. Mine was at 36k miles at that time. Super frustrating.
