I just began to hear a rattling noise on the passenger side. At first I thought it was a lose wiper arm since the noise happens only when I get up to 70 mph. It sounds like it's coming from the lower right hand corner of the windshield. I checked for any lose pieces of plastic trim and couldn't find any. Is it possible for a wheel well to make the noise? Any ideas out there?

Maybe you got acorns in your cowl area like me, I dunno. Maybe, you might find the answer to some of your questions here: http://www.automotiveforums.com/vbulletin/showthread.php?t=480253
Also, the black rubber trim aournd the windshield is just held on with double sided tap, and it does come lose. Mine did. You might check that
