I'd have to check blower motor reacts to different speed settings, then I'd have to check actuator or temp door, under the dash. Go from there.

Jut to add, do you have a lot of air coming from the defrost vents. On some older systems the actuators are vacuum operated and if vacuum is lost, it can default to defrost vents. If that is the case, check vacuum.
