It blows semi cold air so I thought it was low, I emptied a can of R-134a in it, no effect. During the filling process, it didn't even get cooler inside the cabin.

What could cause that? The compressor seems to be cycling ok.

 

Dodgy:

Do you have the rear AC, and if so how is that working? Could be a blend door issue inside the heater/AC box under the dash.

When you run the mode selector through its range, does the air switch to the appropriate outlet?

No rear AC

The selectors work when i switch it in the different settings.

I was thinking it might be really low, but 1 can of the blue Ice NASA something R-134a should have at least made the air cooler. It took the whole can.

One thing I haven't checked is if I get some water dripping when I'm idling with the AC full blast.

 

Dodgy:

I think the next step will be to get some gauges on the system to verify the 134a level, and see what the pressure readings are.

I have a 2005 and have the same problem. I do have rear AC. I was able to put a guage on it and it read that it had the correct amount. what next

 

About the best thing you can do with these 2005 dodge durango's

 

The Expansion valve controls flow to both front and rear evaporator cores. I,ve changed quite a few especially on ones with front and rear a/c. In all cases the rear blowing cold and the front blowing warm typically is what i've experienced.
