2000 Cavalier Vent Flow Problem

I have a 2000 z24 cavalier with a 2.4ltr. The air blows through the vents at the face and feet on mainly all settings. It will spit a small amout out the defrost. The fan speeds all work correctly as I put a new resistor in last year. Can anyone save my back before i go digging under the dash? Thanks Derek.

The controls are cable operated, most likely the cable fell off one end. Most common is the end at the HVAC box.
