Re: 97' blazer... have vacum but still no air from vent!!
i would replace the hose going to the vacuum ball.
It often degrades and cracks and causes the vacuum ball to lose vacuum.
Replace all the vacuum lines. I think they are 5/32 and are easy to swap out. Just go to your local auto parts store and get some rubber windshield washer tubing.
I replaced mine and everything has been great since.
BTW, check all vacuum connections for cracks and leaks.
Actualy pull the lines off and look for any failure.
