O2NavyBlue, Thanks for the reply. I did the brake test you ask and no, that's not the sound. Also I wanted to make sure I'm explaining things correctly, so I took my car for a test drive to see if I could hear the noise again and it's not actually an air sound, but a motor type device that's turning/winding or something of that nature. As a matter of fact, the sound makes me think of driving on the edge of a highway that has the warning grooves when you get too close to the edge...? Again thanks and I'll have this checked out. If any other suggestions, just let me know.
