I removed the glove box, and also the panel covering the pollen filter. I cleaned out the filter, and reinstalled it. Feeling around under the radio, I found some wires that might be tapping on plastic on bumps, and put a small towel in there to keep them from being able to jiggle against the plastic. I then went on another test drive with the glove box, and cover still removed. It seems that my "noise isolation device" had been malfunctioning previously. He now says the rattle is coming from the "A" pillar on the passenger side. Is there a bundle of wires that run down that pillar? How do you remove that fabric covered pillar cover? I pulled the weather seal back and peered in there, but did not want to break any little plastic bits/clips, etc.

Thanks again, and I am sorry for the mis-information in the original post, concerning the location of the rattle.
