Hi! Please try this. The big hoses that attaches the aircon blower and top vents might have fallen. You will need to reattach the hoses to the top vent to blow air. It'll work, HOpe this helps and have a good one!
Check the vacuum under the hood going to the fire wall into the car,there will be a vacuum reservoir,or check valve in the vacuum line that maybe damaged,then check the vacuum to the control ,in the dash.
Your technician is correct, the doors are vacuum controlled but depending on what control unit you have you may have a more complicated issue than stated.
