I have the rattle, but mine is on the driver side of the dash. I find that if I apply some light pressure to the dash at the defog vent, it clears. Took it to the dealer, and because it was raining, he said his tech wouldnt be able to do anything (go figure)?? Anyways, I am going to try to shim the area in a couple places and I think that may take care of it. Will advise.
