What happens if I unplug the max air motor on my Vibe? on 2004 Pontiac Vibe

The door clicks open and shut constantly if I turn on my defroster which I need at this time of year. I must hold in the max air button to keep the door from opening and closing. But then it uses only recycled air from the interior of the car.
