It is a 1999 with the V-6. I checked the vaccume hose connections under the hood and the ones I could get to under the dashboard and behind the radio but none of them seem damaged or dissconnected. Still though, I have no vaccume pressure at all. Everything else works fine, the a/c and the heater; it just comes out of the defrost and not the vents. What could be the problem?

Sounds like a vacum problem still... as vaccum opens and closes the doors...
Check the line very closely from the engine back to the firewall.. had a few burn on the exhaust manifold and one where the vaccum resevoir (what holds the vaccum) was cracked and wouldn't keep enough vaccum to run the doors...
But my vote is check for a gray line broken (burned) by the right exhaust manifold in the front of the manifold (right behind the alternator or so if I remember)

A problem like you describe is almost always vacuum related. Either a hose is off,blocked or the control is bad or sometimes I have even found something had fallen down thru the defroster vent and jammed up one of the doors inside the heater case. Better get it repaired winter and frosty windows are not far off.

the blendoors for the a/c system in the dash may be stuck closed. I am not sure if there is a relay or switch but with a little diagnostic time it should be an easy fix. possibly a vaccuum line if defective.

The doors work by engine vacuum. There is either a leak or the function switch is faulty.
