Vents in cabin cannot be regulated. No cold air comes out except to floor.

Good afternoon.

If you have floor vent, then you have vacuum to the control head.

The vacuum rotary valve behind the dash at the control panel directs vacuum to the different mode doors.

I attached diagrams for you to follow.

Where is the vacuum-line from the vac-reservoir connected to the intake manifold? This line is missing at the reservoir.
