A couple months ago, a bolt suddenly appeared on the passenger side carpet of my 97 Civic HB, under the dash. Now I have developed a noticeable rattle somewhere around the glove box when I go over a big bump. Even when I empty the junk out of it! :-) The bolt is black, hex headed, about an inch long, and has a lock washer and a flat washer on it. Before I try and squeeze myself under the dash to take a look, has anyone else had this happen? Any hints on where to check first? Thanks. -P
