Help! AC stuck in default mode

[Boeingman]

I have 96.My AC system blows cold air,fan speeds work, but it only blows frm the defroster and the floor vents.
Doesnt matter which control pnl button is pushed, no dash board vent air comes out.
Changed the check value under the hood with no luck
Now what ???

That's the only problem with these Automatic A/C systems. Sometimes the blenders will get stuck and only stay in one position such as in your case defrost. I have had this happen as well. I disconnected my battery and then reconnected and that worked but it can be a different case on yours. Good luck.
