Well, thanks to your diagrams I discovered the problem. By laying on the floor and looking up under the dash with a flashlight while pushing the defrost/heat button I could see the defrost door wasn't opening. I sprayed some lithium grease up there while moving the door worth a long screwdriver. It worked. Now it opens and closes like it should. Good thing I don't need to replace the door as it seems the only way is to remove the dash first! I really appreciate your help.
