DASH RATTLES. Simply put I've decided dash rattles are one of the absolute hardest things to diagnose on these things.
Cold weather: upon startup I have a buzz-like rattle that eventually goes away after the heat runs for a few minutes and (what I assume) the plastic expands.
Everyday: i have a rattle somewhere on the passenger side airbag area and just recently since I put my congo cage back on I have a rattle in the A pillar.
I spent most of today trying to track down the passenger side noise without digging too terribly deep into it. I had the climate controls, radio, and glovebox out and was pulling my hair out trying to find it.
Give me seized or stripped bolts any day.
