2012 Laramie 2500. Dual zone climate. Every option works, i can switch the mode selector, run the dual zones independent, fan speeds, etc. The only thing that doesnt work......hot is cold, and cold is hot. Ive replaced the control head unit to be sure, and visually inspected the entire system and verified all of the mechanics are working as and when they should. The temp controls are literally just backwards. Has anyone experienced this?

Can this be a programming issue, ie pcm or bcm flash update? I would have expected this type of issue to be resolved with the head unit, but it was not.

no, I sure didn't. Couldn't get a reply on any of the half dozen forums I posted the question on. Ive just been dealing with it this whole time.
