I have a 2006 Highlander Hybrid. After driving for at least 1/2 hour, I begin to notice a rattle coming from the battery air vent under the rear right passenger seat. It seems worse when there is a strong cross wind. Any ideas would be greatly appreciated!!! Kind of almost sounds like a "shield" or something that is making the rattling sound. It's not loud, but just enough to be rather annoying, since there is a direct line of ear-shot to the drivers ear.
Thanks a bunch to anyone responding. Tony :frown:
