lol yeah, i mean i don't get what it's supposed to be.

 

Lol, KD.
I was told that the slider is used to allow outside air in through the center vents. Similar to the slider on the HVAC, but the vent slider on the HVAC allows outside air in through all the vents while the center vent slider only allows outside air in through the center vent (assuming you have the HVAC slider on recirculate).

I just checked. Yes, it is specifically put there to allow outside air through the center vents only.

 

like concentrating the outside air through the main vents?.... like air coming from the engine bay to regualte temp or something?

Edit: Always enlightening us up john lol

 

hmmm i would of never guessed that. your the man silver coupe

 

It controls the intermitten wipers and the washer fluid on the back hatch.

 

not the button

 

i think we all know what that button next to the slider is for

 

not to be an ***... hehe but the question was already answered ^_^

 

looks like rear wiper if your talking about the button. and i haven't figured out the blue head thing either i haven't noticed any change in my vents messing with that.

 

Crack you window, drive on the interstate or the likes and turn everything off HVAC related and move the slider on the vent, you should notice either warm or "cool" air coming in only from the center vents, assuming the HVAC slider is set to recirc and not vent.
