So I've located the rattle! Please see the picture with the arrow. If I apply slight pressure to that point, it stops. There's a clip or something in the pillar that's rattling against the pillar.
Is there a way to remove the trim and get in there? A small piece of foam should do the trick. Or, is this something more suited for the dealer?
I'd rather do it myself and save the trip if possible.
Thanks in advance for the help!
