what is this part and what does it do???
95 grand am v6 that little grey hose is broken, i need to no the purpose of it and that part name... thank you

If the part you are circling has the heater hoses to it, then I would say heater control valve, I'm guessing here. Hope that helps!

Looks like the elbow that attaches to vacuum reservoir. Does your air flow inside go from vent to floor to defrost okay? Or is it always coming out the defrost? If so- that is your issue- a broken vacuum line- find the other end, or look for the reservoir- sometimes behind the inner fender in font of front wheel.
