I found a black little hose coming out of the wire cluster shown just hanging there. Thinking it probably slips over the white one coming from the canister? Thank You so much.

I have broken white hose, I plugged it, completely removed the vacuum valve, and defrost and vents work fine.

I think this is the blend door valve, outside/inside air?

I don’t think so. At least that is not what I have on my trucks. Would you post a picture of what you are looking at?

Yes. I’m surprised you didn’t know that since you been on here for 10 years and there are several threads about the topic.
