It more and likely is the servo motor (s) that are the problem, when you turn hot to cold and defrost they cycle the vents in conjuction and are a common failure on this model.
The ones that fail are accessible if you remove the right underscuttle panel and the glovebox.
Black motors with a double wire, usually have a red connector on the end.
