With your a/c on full if you put your finger over the hose can you feel air blowing out? It wont be too much but you should certainly be able to feel it, It should have the air pressure of say an aquarium pump

I also had dirt caked up under the rubber around the windshield, which certainly could have been contributing.

Good luck and Let me know if any of this helps, I certainly know its no fun having to drive a musty smelling Truck.
