there is a vacuum line broken somewhere in the dash,I can run another one without taking the dash apart,however how would that be effected when im not making vacuum is there some kind of vacuum ball that holds vacuum located in the dash somewhere?

I was thinking of running a new vacuum line with a check valve,but I still think the vents will switch back when im not making vacuum.
