    I am noticing a very annoying whistle above 35mph on the drivers side. I have checked some threads here that suggest taping over the screws under the mirror, and have done so with some clear tape but the noise persists. Any other suggestions on the cause? I have also treated all the door seals with some rubber conditioner/cleaner that hasn't helped either.

    Try to move the windows a slightest bit to see if that effects the noise? Or if you lean on the door? Or something else? Try to figure out where it comes.
