Inside the Glove Box 2003 Cooper S
 

Inside my glove box in the back left corner there is a black little round knob that turns with a hole in it, what does this do? Nothing in the manual about it. Sort of works like a cooler drain. Thanks

The knob inside the glove box is turned to allow cold air to cool a drink. Open with hole showing to cool or close ro shut off.
