I am glad to hear that some mega cab owner say there a/c works fine. I think a 55,000 msrp truck should have a functioning a/c unit. What I call functioning is to have a comparable a/c unit to a ford or a chevy of the same year. So don't compare your new mega cab to a 1978 ford pinto. Look I love dodge trucks that is why I own 3 of the new mega cabs. Please quit writing into the post that you can crack window because truck is sealed to tight. Look I can open all four window, rear window and open the sun roof. Still cant even cool down the leather seats to make it comfortable to drive until you have gone down the freeway fforabout 40 miles then it starts to work ok. All truck have been in for warranty and yes damper doors changed. I think the rest of the truck is great. But if you would go see what a ford or chevy a/c was like you would also have to agree the mega cab a/c is a joke.
I appreciate all who writes in to tell me how to work my a/c I have been a a/c contractor for 15 years residential commercial and industrial. So I think I know how things work. Like when a contractor tells us he needs a job done cheap. We use flex duct that restricts the air but is cheap. So oobviouslythat system wont work as well a real metal dductssystem I will eveventuallyhen I get the time jerk out my dash and maybe change the evevaporatornd the blower assembly to make the ssystemwork up to part. But I don't think the average guy thats spends this much for a truck should have to do this. I think Dr z or what the heck his name is should have engineered the a/c system to work in the vehicle. AT least as good as a ford or a chevy.
