The problem is caused by the servo mechanism that opens/closes the ventilation door (fresh air mode/recirculate air mode). Note: Some models use vacuum to open doors

This is also called a blend door, you have to remove the front dash trim to get to it.

The IP and dash removal is hard to describe and difficult to show.

I cannot enlarge the pics, or zoom to specific area. Best thing to do is to go to local library or community college and get online to Michell.com or Alldata.com and print procedure, these are free services. Repair manuals like Haynes sometimes show the procedure. The best resource for this is original factory repair manual, available at Helm.
