I second that - there's a good chance the flap in the AC diverter box (middle of the three boxes under the dash) is broken. The cable will work the lever on the shaft but the flap doesn't move. I was able to repair mine with epoxy earlier this year, but it probably won't last. New boxes are about $100!
