So when I bought my '94 Vectra, I knew the dash air was not working and controls were "stuck" on defrost. When I pulled the dash apart I noticed the lines all looked good but were not getting any vacuum. I traced the vacuum hoses under the hood to the "vacuum ball" which looks to have two hoses connected. These hoses run under the coach to a contraption above the front axle that has air hoses running into it, which I believe from research is a "venturi style vacuum pump"
The bottom hose that is not connected constantly bleed air out (and will drain my air tanks sitting over night). The upper side hose has pressure, but I don't feel any vacuum from the lower hose.
Before I start digging into it, anyone shed light on how this thing is supposed to work??
