I had a big detailed answer, but it disappeared before posting. Here is the Readers Digest version. 1. Is the motor running? 2. Are ALL vents not putting out air, including the windshield defroster? 3. motor not running, check the fuses. 4. motor not running and fuses good, motor wire connections, and good wires? 5. Use a lit candle under the dash with the vent motor on, see if the flame flickers, indicating air is moving from the vent motor, but you may have a bad vent hose connection or it just fell off. 6. You may have a big friggon rat blocking the air flow. (Make sure it is dead before removing it.)
