Help! I need to know the name of this part

Ford Edge 2007. There is a white plastic piece next to my blower that seems to have broken. I want to do a little research to see if this is something I can tackle or if I need to take it in. I just need a jumping off point and the name of the part would be very helpful. When the green plug is unplugged it’s fine but when I plug it in it makes a horrible clicking noise. I took a picture to show where the blower motor is in reference to the white part I believe snapped. (I’m pointing to the part I need the name of) also if you know what it does that would be great because it doesn’t seem to be affecting anything.

Blend door actuator.

The linkage for the recirculation (air inlet) door actuator is broken.

You should get that fixed before it gets too cold.

Thanks guys! I got the part off rock auto and it’s something I can replace myself. You guys are awesome.

I’m curious, which one did you buy; the blend door actuator or the air inlet/recirculation door actuator?
