Here is a (in my opinion ) a great way to help our extremely poor engineered Air Conditioning system in the 5th Gen Rams.

Where did you install it and what does it do and can you provide some pictures of the install and some supporting data?

What is poor about the design exactly that you think a brass swaztica is going to help?

I didn't have any issues with my 2021 AC or my current 2023 AC. In central Florida as well. I typically have to turn mine down after driving a little bit. And I stay hot lol

I have no issues with the AC on my 2025, my 2019 had crap AC.
2019s and 2020s (and some 2021s if I remember right) had poor A/C performance from the factory very frequently. Turns out, it was due to a badly designed HVAC system in the dash. There was a TSB for it, involved replacing the entire HVAC box in the dash, pretty involved (labor) fix.
Some 2019 and 2020 owners (me included back when I had my 2020 Limited) installed a check valve in the heater line to the cab, reducing coolant flow in the summer to help boost A/C performance and opening it up in the winter to allow better heat.
If memory serves, late 2021s and newer had the redesigned box from the factory, hence much fewer issues for them.
