I pulled the passenger inner fender liner to change that side door check tensioner arm and hanging there is a round ball with what appears to be a vacuum line back to the engine compartment. looks like it goes to a small junction area on the pass. side of the engine. has a blue fastener on that end. i'll post a pic when I finish.

It holds reserve vacuum for your vent controls. If you disconnect it you won't be able to change which vents your air blows through

It shouldn't be hanging like that, it should be fastened near the top of the fender like this.

good to know. when I put the liner back in due to it's size, it sits higher w/o pulling on the line. I don't have the t connection in the fender well. it's a straight shot to a 6 or 8 pack connector in the engine compartment.

As stated above that vacuum reserve ball is for the HVAC. It sounds to me that you're talking about a different vacuum reserve canister which is in the same fender but in a different location when you said:
