The air conditioner compreswsor works fine and cold air from the defroster. on 1997 Buick LeSabre

The doors dont work to change air flow to Mid or Floor. I've checked vacuum lines and appear to have vacuum to the control unit. Is it my electronic climate control? This occurred after I installed a new engine. At the same time I cant get the ecurity alarm to clear.
