Does anyone know where the Vacuum controlled HVAC motors are located in a 98 GT?

I'm having an issue where when I turn the HVAC system on, the air comes comes out of the front window defroster and the floor vent, no matter what mode the control dial is set to.

I have been reading that this indicates a Vacuum leak, or disconnected vacuum line. I located and smoke tested the black Vacuum line from the engine compartment back as well as the engine compartment Vacuum lines, the yellow Vacuum line to control motor located behind the radio, as well as the white Vacuum line to control motor located behind the glove compartment, and all tested out good.

Question is... where can I find the Vacuum control motor that the red and blue Vacuum lines connect to?

Not my post, but here is a diagram I found of the system.
