It may be a problem with the direction control knob. I had once changed my blower direction to the foot and then it refused to come back to the regular mode. The knob had to be replaced.
I'm sure this is the problem and you may have once directed the airflow to the windshield. In this mode, air also comes out of the side vents which is directed to the side glasses. Now after switching the direction flow back, the knob as malfunctioned.
Knob may move, but the internal connection is lost. Try to use other direction modes to check if the knob is working fine and air is directed elsewhere to the foot, etc.
Its not easy to clog an air vent. However, you will have to open up the dashboard to clean it if that's the case. Should cost you around 750 bucks IMO.
