The cars ac has multiple issues i believe as i recently changed the blower motor but i've always had this code but cant figure it out. I even bought a part that says its for this year make and model but cant find any info on it being installed or a video of anyone attempting this repair. Also i thought it referred to that door u can see right by the battery and that door does open and close with operation of the fresh air button. Current/stored code B112B-07 The Actuator motor for the ram air / air recirculation flap has a malfunction. There is a mechanical fault. I also got side traced into thinking this could be the ram air flap in the manifold? I would appreciate anyones help as i am at a dead stop and cant even find the location of a faulty part or any mention of the code.

Also here is a pic of the part I thought the code was referring to I can’t seem to find the location of this part nor any video or install mention.
