Hello, are you getting any air flow from the floor vents or defrost (to the windshield)? Or just no air flow at all? If so, do you hear the blower motor running at all when you turn the air on?

Here is a diagram of the air flow through each of the mode doors, if there's no air flow from any location at all, then most likely the blower motor is not running.
