No air blowing out the A/C vents

Hello,

It sounds like you have a faulty mode door actuator.
The mode door actuator or motor controls which vents the air will flow. Many times, it fails or gets stuck in one certain position and won't allow it to change the setting.

The mode door actuator is located behind the glove box.

Here is a helpful guide on mode actuator:
