Exposing this made the sound very loud and noticeable when I tried driving it again. That being the case, the first thing I did was loosened the two bolts and took it for another drive around the block. The sound was gone. I tried tightening both bolts again, and the sound never returned.



Somehow, that did it, and the sound was gone after that.

Thanks for the update, that's great to hear. You got off lucky, actually. There's a TSB on dashboard noises that involves removing the dashboard and applying some felt and zip-ties to the frame behind the dash. I'll have to see if these bolts do the trick for me, otherwise I'm taking my dashboard apart this winter.
