No airflow out of the dashboard air vents. The rear seat vents work and cold air comes out. How do I repair the front vents to get the air flow?

Cold air only comes thru vents on passenger side while air on driver's side is warm or just regular vent air coming from outside of the car. Not fixed because i don't know what is the problem.
