Would every one please try this

[OkSlim]

I was driving my 09 S the other day and rolled the rear windows down to get some fresh air in the car.

The next time you are going to be driving between 55 and 65 with no one in the back seat, would you guy please roll down your back windows and tell me what happens?

Thanks

driving at highway speed and rolling down only one rear window will cause air concussion/vibration whatever you call it. That happens on a lot of cars I have driven

to equilibrate the air, open the rear window on the opposite side too, it will help

i'll tell you what happens... the air vibrates and hurts your ear drums

A lot of cars that are aerodynamic do that.

wat happens is, if u open the passenger side back window only, u get air flowing towards the driver, so u dont really need to open any other windows....likewise same happens if u open the drivers side back window only. however, if u open both the effect cancels out and then you get that vibrating sound effect that gets annoying. thats my experience anyway.

Isn't there another window helicopter sound thread in here somewhere?

My top-of-the-line Buick Park Ave. used to have wind buffeting with just the two back windows open. I suspect this is common to most cars.

You think its bad in a Corolla.....get in Tundra!
You'll be lookin for a Huey making a pass.

I love doing this to unsuspecting passengers!
