Question about 2006 Dodge Grand Caravan
I have a three zone automatic temp control
The air diverter door in the heater/AC case is not moving. The cause could be anything from a stuck door to a bad vacuum line, bad servo (door actuator), or the rotary switch on the control panel.

Hope you have the same set up, sure you do. You may have either crossed your vaccum lines or when you were putting your heater/ac box back together or you may of pinched the vents somewhat closed. Cycle through the different zones to ensure the vents are moving as your are selecting (defrost, floor, ect...) If you think the vaccum lines are correct then you may have a reassembly issue with the Heater/ac box. I had the same problem with my 2000 Dodge Ram 4x4. Use the KISS rule "keep it simple stupid" start with the vaccum lines and all your wiring to the motors, make sure everything is plugged in. Hopefully you'll find it there before going back into the box again.

From what I hear it is a vacuum line issue. Mine is doing the exact same thing. So, I am going to get a diagram and try checking the vacuum lines to see if any are loose or tore
I go under the dash and feel the air flowing out the floor and it is coming out of the defrost, also. I noticed under the drivers side today that air is flowing and there seems to be a gap in between a part under there. There was some material stuff I saw around the edge of it that sticky brown stuff and it sometimes before came out my vents all the time. Anyways, not sure if my air is just not sealed good to blow out the vents but it is something that happened not long ago and we've not done anything under our dash area.

It sounds like you have a blend air door stuck. This is in the housing of the heater a/c blower unit under the passenger side of the dash. There is a motor on the top of the housing that could possibly be stuck or on working.
