Hope you guys can help a gal out! I have a 1989 F150 that we just got that is stuck on defrost vents. I am reading here that this is an issue w/ the vaccum lines. I was looking at schematics and seems I don't have the canister that runs the vaccum. I think it is the "actuator". Is that the correct word? ANY idea how I can go about finding one?
