Well, here is an update! All works well and by fixing the vacuum leak I had the car now runs better all around. I guess just that slight leak of a hose disconnected really starved the rest of the system of its needed vacuum. Tranny shifts a hair smoother, idle is smoother although still not as perfect as I want, heater controls all work much better and my heater valve actually closes now. That and I learned an awefull lot of how the HVAC system works since I could see all of it and actually did a test of it before putting the dash back in. No need on the 190 to remove the airbag and steering wheel. Although I am sure it would have been a hair easier to remove and re-install the dash it still slid by!
