Hi All. I'm a newby. I'm having trouble identifying a part, using available diagrams and cant find my damn repair manual.

I have a 1994 f150 5.0

Any help would be appreciated.
I have attached a photo of the part, which I have circled in red( borrowed from another posters photo)
Thanks

 

It looks like the device that controls the blend door for the heater. I can't remember what it's called, but I think that's what it does.

 

Thanks. That helped me find it. Blend door actuator.

 

That's the fresh air/recirculate actuator from what I remember. Not the blend door actuator.

 

The blend door does not have a actuator. The blend door is cable controlled.
As noted above that is the vacuum motor for the fresh air/recirculate door.
