Having an issue mostly similar to this. No air comes out of the vents, can hear the blower running. Although mine doesn't blow anything from the defroster (like the below thread). I can change the positions and it changes the flow except nothing really comes out (but face only for example, the trickle comes out of the proper vents) It was working perfectly fine and has been (except for one instance I'll explain below). Tried recirc and it didn't change it, although I didn't run it in recirc for long at all.

About a year ago it happened on a road trip (like today). Then after a couple of hours of running it blew a piece of paper out of the floor vent. Not sure if this is the same thing, I will check to see if there is a blockage at the recirc screen. I haven't heard any vacuum leaks.
Thanks for the help...
