    No, it draws air in from the cabin at the top of the back seats. THere is a cabin filter behind your glove box you should change. But if you heard the fan running, it is a sign the batteries are hot, so it could mean a cell going bad, or the cabin was hot or excessive charging or discharging or long drive.
