It sounds like you have left off or damaged/pinched your vacuum harness to the hvac control head. Check and make sure you have solid connections...it could also be that you twisted the box when you pryed it off of the firewall and broke the defroster valve (the little door inside the case).

It just so happens that I have the same problem right now. The air blows good through the vents but hardly at all from the defroster or the floor.
I found that this mode control unit seems to be weak 'cause if I assist it to full travel then I have full air flow.
This is on the drivers' side.
