How do I check that?Have you checked that the blend door is functioning properly? If that's hung up, it'll never get cold.

You'll have to check it with either a very good scanner or take the HVAC apart. The actuators are known to break and more than one door has fallen completely off (which causes what you're experiencing).How do I check that?
All vents blow hot when I set the heater to full HIGH (hot), and all vents switch from hot to ambient when I switch to full LOW (cool), so it seems the doors are working. Unless I'm misunderstanding what the doors do...You'll have to check it with either a very good scanner or take the HVAC apart.

There is one door that switches from the heater core side to the a/c side. If it's stuck or the actuator is broken, it will blow a combo of both hot and cold.

FYI there are a couple of TSBs regarding AC performance for 2014 durangos.Got a DIY AC recharge kit and used the pressure gauge to check low pressure port, with engine running, AC on Max with recirculate engaged. Pressure indicated ~40 psi on the gauge (middle of the green zone).
Ambient temp about 62, and the vents in the front only got temps down to 67-77 (depending on which vent you checked). Rear vents only got down to 68.
So, weird noises, pressure seems ok, but AC isn’t blowing cold at all.
Compressor? Other ideas?
