2000 Camry Vent Mode

[cougar]

I have a 2000 camry, 70K miles.
With AC or heater ON, I get air from vents on feet, defrost, and front
vents on the side. No air blows from the front vents in the middle.
It does not matter which option I choose on the vent mode switch (Face,
Face&Feet, Feet, Feet&Defrost, Defrost).
I opened the dash and got the mode switch out. Checked its continuity
as per Chilton's manual, and it is fine.
Does anybody know the continuity tests besides whats already in Chilton's manual?
What else could go wrong that causes this problem?
I have opened most of the dash, but not the top dash. In order to reach the ducts, do I need to open the dash completely?
Chilton's manual does not provide detailed information on reaching the ducts.
Also, with the vent mode switch disconnected (most of the dash is dismantled), I connected the AC switch and the fan switch, then I started the fan, and the air is still blowing on feet, defrost, and front side vents - no air from the front middle vents.
Somebody told me that the damper is not in the correct position.
Is the damper located under the fan assembly (blower) under the dash on the passenger side?

Sorry I don't have an answer for you on your vent problem, but, I do have the exact same issue with my 1997 Camry and would like to know if you find an answer to this problem. On ours, you can look into the center vents with the fan on high and the mode selector set to face and see that there is back pressure blowing on what appears to be a filter or maybe a damper. When you switch the fan off, the pressure that was pushing on the filter or door in the vents goes away. So... is this a filter or a damper?? It does not appear to be accessible. any help would be appreciated. I will let you know if we solve our problem first. Rob

The options are (in order)

Defrost / Def+Foot / Foot / Face+Foot / Face.

I can get the middle dash vents to deliver air on the "foot + Face" and "Face" settings only.

Hey guys - my brother has a 2000 Camry with this same problem (little/no air comes through the center vents). What did you end up figuring out about it? Does anyone know how to fix this? Thanks in advance!
