No dual control setup on 2020 RAM 1500

[RoadExplorer1]

Hello! Do you guys think the climate control on my 2020 RAM 1500 does not work because it lacks a dual control setup? If yes, what should I do to make it work? Thanks!

No! It should work without a dual-control setup. But there is something I am missing. Has it ever worked before?
