No Defrost

Hi I do not have any Defrost. My ac, heat work. But i cant get any at the windshield. i checked the vacuum hoses. they all seemed to work. I changed the accuator and changed the heater/ac selector. They didnt work.
I have done the search on here and all i could find was about the Bleand Door. That does not seem like that would be my problem? Also someone said about a Gear in the Back of the truck. Again, that didnt seem to be the problem. If anyone has a thought please let my know.
i have a 2006, v8, 5.4.
thanks for the help.

can you hear it switch when turning to defrost
can you feel air in defrost mode
does it sound normal in defrost mode
check to see if defrost vent is clogged or off

No I Cant hear it any movement or noise when switching into Defrost mode.

A very little comes out in any of the modes

no. there isnt really any sound.

Ok I will check to see if the Defrost vent is off or clogged.
Thanks for the reply.

P.S.
How Can i check that? It seems like it is all in a Box under the dash. Is that where it would be? I will try and find it.
