Blower door and actuator location

I am having the most difficult time locating the blower door and actuator for this vehicle. I am fairly confident that I have rule it down to that being the problem. Confirmation would be helpful, and an exact location would be amazing.

heat and air temps are barely functioning correctly.

Air flow is normal.

When the vehicle is off all knobs turn freely

When the vehicle is on, if the circulation knob is centered on fan mode, the temp adjustment knob turns freely.



If the circulation knob is pointed to either exterior or interior, the temp knob has significant resistance when turning from hot to cold. Noticably less resistance from cold to hot but still far more resistance than should be present.

There is obviously an audible flopping sound when transitioning from hot to cold, at which point all resistance goes away.

When put back to fan resistance goes away.
