I have an annoying rattling noise that seems to originate from the passenger side airbag area. Can't tell exactly where it's coming from, but I know it's not the glovebox since removing it makes no difference. To me it sounds like it's deep inside the dash.

It starts at around 45mph and doesn't increase in volume. It used to do it intermittently, now it happens all the time. We've had the vehicle since new and this just started recently.

Any ideas? Thanks!
