[QUOTE="machoheadgames, post: 432784, member: 18789"] That’s all correct. The off/defrost/heat/vent slider holds the button in off mode which lets vacuum reach the motor to close the flap. When you move the slider to the other 3 positions, it lets go of the plastic vacuum switch, blocking off vacuum to the motor and the flap opens. The switch breaks off with the crappy screws or nuts or whatever they use. Probably 8 or so years ago mine broke off so I super glued the vacuum switch to my heater. No problems since.
