What is this thingy?

Ok, I was filling up some wiper fluid and I notice this plastic tube broken off at the end.

 

It leads back to this joint which located next to the master cylinder and strut tower.

 

What is it and where does the other end that is broken off go to?

im pretty sure that goes from the intake manifold to the hvac system and the vacuum tank in the fender. The hvac system requires vacuum so when the engines off the tank stores a little vacuum so the hvac controls can be operated for a short amount of time when the engines not running.

Thanks, I'll have to looking to that. Would probably explain why I can't switch flow from the defrost and floor. lol
