Hissing in the cabin? Not the Vacuum Chamber.

Ok so when I am driving I hear an annoying static like hissing comming from the passenger side cabin near the fire wall. I read the thread on the "The vacuum chamber" but my sound is different, it is not comming from under the hood. It sounds like the old style air vents changing where the air is comming from. Kinda a hissing, I dont know what else to say. Its loud, about the level that we talk at, and is almost always making noise. Any help?
