Intense vibrations....
Hey guys...funny thing. For the first time I put down my rear driver's side window on my 99 GS400, and had to put it up immediatley because the cabin of the car began to vibrate and the air began to pulsate violently that I could feel the pressure fluctuations in my ear...but only when this window is down while the others are up...
What the heck can this be? I can't imagine toyota would put out a vehicle where the cabin air pressure pulsates violently if the rear driver's window is open at highway speeds?

seriously guys? he lowers the WINDOW and we point to brakes and alignment? LOL
it's because of the fact that the rear windows are 'square'....in that, their shape, on top of being slightly recessed in comparison to the b-pillar, doesn't split the air current that comes into the car. Your front window has that leading edge to evenly distribute the air when it hits it. With the rear windows, think of it as like a soda bottle when you're pouring it: when you tilt it to level or slightly past, itll pour smooth because half the opening is allowing air in. When you tilt it straight up and down, it 'glubs' because it essentially has to gasp for air to push the water out.
this is the same thing that's happening with the window, just no water and many many more times per second. my stepdads highlander does the same thing, as do many other vehicles.
