Actuator installation

Hi,

There are a few different actuators. Since you said air flow, I suspect it is the one for air flow direction (mode door actuator). If that is wrong, let me know.

Here are the directions for removal and replacement of the mode door actuator. The attached pics correlate with the directions.
