I realized today (a day in upstate NY when I didn't need the heat).... that regardless of the fan being off... air still blows in through the vents.... why is this??? and does anybody know how to fix????

thanks...

it is a "feature" that i see in many japanese cars... its like getting free venting without having to turn the fan on. i use it all the time when the weather is nice.

but to answer your question, you can stop the air from coming in by turning on your recirculation button. that will close off the input from the outside...

I'll give that a try later today....

 

I tend to leave my vents open and on most of the time. That way on cold or rainy days, my windows don't fog up. It's good to keep fresh air in you car anyway because the air inside will get stale. You don't want that. P.U.!!!

 

Don't try to fix this, Sergio, because it's a safety feature. A small amount of fresh air enters ALL cars at ALL times, usually through the front panel vents, even with the recirc button engaged. This is to prevent your passing out! Atmospheric air (at sea level) is approx. 21% oxygen and we need about 3% oxygen to respirate. That means that after you breathe the same volume of air seven times, the air in your cockpit is effectively depleted of useful oxygen. Introducing fresh air into the mix prevents drivers from passing out from hypoxia.

My first car, an '86 Volvo 740, also had this feature.
