On most all cars you have a selector control on the dash for selecting the different options such as floor, defrost, panel, mix, and so forth. This control depending on the car operates a flap/s near the heater that sends the air in the direction you select. Some use a cable to do this and others use a vacumn switch connected by vacumn hoses to a vacumn operated valve that opens and closes as you select. If any of these parts coming from the selector controll goes out it could cause the problem you described. In most cases I have had like this either the selector controll switch went out or the cable or whats it connects to came loose or broke. EzForJesus

Bruising would be the most llikely physical problem. Even more significantly, it would be important to reevaluate your relationship if the "hard blow" was caused by a partner.
