Does any air come out the heater when in defrost mode? If so, adjustment or possibly rubber again. I don't recall if that valve has a rubber lip but it might. If the adjustment, flapper and duct are OK then check the spacing of the trim strip over the slots. As I recall, on some dashes the standoff spacers could move and it could screw down and get very close to windshield blocking flow.
