No air from any of the top vents?

Im not getting any air at all blowing through the tops vents of my '88 vert. The air all comes out under the dash on both sides. What are the areas I need to be looking into to get this fixed?

Selector buttons on the climate control logicon are probably not working. They operate motors which redirect air flow. The fix would be replacing it or re-soldering the board.

Before pulling things apart, if you have a multimeter test the leads on the logicon.
If they are good then test the motor leads to be sure. If both are good check to make sure the plates that block and direct paths can move (some resistence is normal).

But like RotaryPocket88 said, logicons are usually the case. But it doesn't hurt to check everything first.

the vents above the one on the door arent supposed to blow air. they come on when the defrosters/defogger thing comes on
