interior vent noise?
 

ive noticed a swooshing sound like a valve opening and venting air or something of that sort from inside the car. sounds like it is coming from passanger side dash? i dont know what it is, its very faint. happends when i use the car, within the firs 5-10 mins from start up. not sure how else to explain the sound, hope you guys kinda understand what i mean. any ideas? thanks
