My '93 Accord has developed an annoying rattle in its dashboard, just
below the lower driver's side corner of the windshield (It sounds like
it MIGHT be in the vent for the defogger). It rattles only when the
car hits bumps, and has nothing to do with running the fan, etc. Has
anyone had a similar experience, and figured out what it was/how to
repair it?

Thanks!
Ben
