Summary: I had this problem, and Google only wanted to talk about the famous recirculate door breaking off and landing on the intake from the blower motor, causing air to stop flowing (or crawl) through all your vents whether it was AC or heat - whether you had it on defrost, chest level, floor, etc. So many people like myself wondering what the problem could be if it wasn't the recirculate door blocking the airflow from the blower motor in these 3rd gen Dodge's. Pictures at bottom for solution.
Well I tell you hwhat, Bobby, I took the glove box off and removed the blower motor. Stuck my phone up in the hole and there's a little access way that goes towards the drivers side to reveal what I think is called an AC condenser. The thing on the back of air conditioners with all the metal fins to cool it down. This could be your problem, if it's caked with dirt and grime. Mine was. There is no cabin filter in these models, so maybe that contributes to this, I don't know. Just the level of grime that was on mine was enough to almost stop the air from coming through altogether.
Apparently, all air has to pass through this thing no matter what combination you use (heat, AC, floor, mid-level, etc.) I took a baby bottle scrubber and bent it at a 75 degree angle and literally scrubbed it blind with dish soap and water. Boom. Put everything back together and the air comes out so strong it's nuts. I crave literal frost on my windshield, or a beam of glory descending upon me when I step outside in the heat/humidity and my glasses instantly fog up from the power of the AC. I now have these abilities since cleaning the AC condenser. I had forgotten what it was like when I first bought the truck. Slowly over time this thing gets weaker and weaker, you'll notice a huge difference once you clean it. Fan level 4 now requires hearing safety as decibel levels may be unsafe for elderly or young children, take precaution.
I hope this helps someone else because I searched for days to no avail. Check your AC condenser status!
