Question what is this?

whats everyone, I was checking out my engine today when i noticed there is something broken next to the pcm. its black and has three wires connected to it. but one of those wires is broken off. my car works fine but my ac doesnt blow air from the dash vents only from the defrost and the floor. i was woundering if that has something to do with it. here is a picture of what im talking about.

It's called a check valve. One line goes to a vacuum resovoir. Which is the one that is broken. And the other two goto the intake and one goes inside to the controls. Atleast on my v6. )
