Whistling Noise on Driver Side Over 55mph?

[micojones]

It's happening to my car too, and only on the drivers side. I just bought my car, so I don't want to put some gnarly looking tape to disturb the air flow. Has anyone tried anything else to stop the noise?

I haven't noticed it on the xd, but normally between the radio and exhaust I dont here much. lol. But it is not a probably with xDs to say. I have had many cars that have the weird whistling right there at the side mirror and the a pillar. mostly on compacts. My mom's Kia Rio has the same thing sometimes.

I believe it's a combination. One you think of a balloon that you open just slightly after filling up with air. You can hear the hiss of all the air trying to fit through a small opening. Well as the air tries to pass between the smaller opening between the mirror and A pillar/ door it creates this sound. And two like when you blow air across the top of a bottle opening you hear the whistling due to the movement of the air in the bottle. Well when the air pass between the mirror and window it causes the air on the mirror side to mix and turn and create a sound.

My xD is still doing it, though strangely the pitch of the whistling has changed to being almost out of my range of hearing, so it's somewhat more tolerable now, plus with winter coming up I won't be rolling my window down for the next few months anyways . I still haven't figured out where exactly on the mirror is causing the issue; visually there seems to be no difference from the passenger mirror, and I can't exactly climb out there while on the freeway to mess with it

Between the whistling, the rattling in the dash, and the bluetooth module being dead in the AVIC it may be time for a visit to the dealership.
