There should be a hose that goes through the firewall to power the vacuum to operate the inside flappers and vents for the AC stuff.

On the AC evaporator there is a vacuum can that is about 4" in diameter and about 31/2" long. This can has two inlets or one inlet and one outlet on the back side (end of can that faces the passenger seat) the bottom inlet has a hose attached that connects to a fitting on the intake manifold. The top inlet has no hose connected. What should this top inlet or outlet be connected to? Thanks for the help!
