Hi,
It sounds like you may have more than one thing happening. As far as the air flow direction is concerned, it is controlled by the mode door actuator.
The actuator is located at the end of the HVAC box under the dash. I attached directions below for replacing it. However, before doing that, check to make sure nothing has come disconnected. If everything appears okay, remove the actuator and keep it plugged into power. Change the airflow request to see if the actuator responds.
I attached the directions below.
I hope this helps.
Take care,
Joe
