I’m not sure about the newer Sn cars,but on the early ones ,there is a vacuum line that runs across the fire wall from the plenum that controls the mode door- it usually rots in half

Have you checked the tiny vacuum line that goes from the motor through the firewall? Is it connected? Is it damaged in the engine bay?

Give yourself the best shot at a "easy fix" and see if you can find a leak in this vacuum line. Because if the line is good, then the trouble shooting gets more involved.
