No air flow?

So, the blower turns on, but you get no air out of any of the ducts? So, nothing at the floor, dash, defrost? Do you get anything if you select recirculate? That would pull air from inside the vehicle in the event that the intake duct was blocked. If you get no airflow then, I suggest removing the blower motor and checking if a rodent or similar made a home in there that is blocking the airflow. To do that on this vehicle involves removing the dash to get to the HVAC case which is then removed and taken apart to get to the blower motor and remove any blockage inside.
A possible option would be to take an inspection camera and snake it through the recirculate door and see if there is something blocking the airflow across the evaporator core.
Now if you select recirculate and get airflow then it could be blockage on the intake air duct, which is located under the cowl panel where the grid is between the hood and windshield. I've seen critters in there, ice built up, leaves and even a swarm of bees that blocked the air inlet. To look at that you can just look down through the grid at the intake (circled in yellow) and see if it's blocked.
