This is a symptom of a broken blend door. Typically, to fix a broken blend door, a mechanic will disassemble the dash and replace the entire plenum box. It is very labor and parts intensive. There is a DIY solution called heatertreater, which provides instructions on how to replace the blend door, accessing the plenum box by removing the glove box rather than the entire dash. It is a much better method to repair a broken blend door than removing the entire dash and replacing the broken door with another dysfunctional plenum assembly that will break again over time.
That is why Aluminum blend doors, recirculation doors and modes doors would be preferred over the plastic OEM blend doors.
