Goes to the vacuum canister that is behind your bumper on that side.
Thinking your air/heat is just coming out of the defrost vents?

You definitely want to hook that back up to the vacuum ball. With it disconnected, it will affect how your jeep runs, and it will prevent your climate controls from functioning correctly.

Ok. Thanks. I just had a major tune up done. The jeep was running fine after tune up. I've noticed this broken tube yesterday, it wasn't broken just a week ago. Also, noticed jeep is hesitant accelerating at slow speeds since this week. Will fix the line.

And cruise control, if I am remembering correctly.
