Classic sympton of a vacuum problem. Start at the source (don’t forget the check valve) any look for why the vacuum is not reaching points it should.

Does cool air come out of other than the dash vents? If not how do you know it is working? Does you car have vacuum controlled vents? How about wire or electrical controls?

So vacuum is reaching the motors that control mode but the levers and doors are not moving,you have a jam in the linkages. Did you actualy measure how much vacuum is reaching these vacuum motors? your dash must be in pieces as it is not easy to get to these points.
