Rattling interior - Help!
 

My 2010 Elantra has less than 5000km on and it has developed a rattle in the glove box (latch is loose) which I will take in to the deal to have fixed. We just started to notice that there is another sound emanating from the windshield/front dash on the passenger side. It isn't quite a rattle but it sounds like something is moving and tends to happen after driving a while with the heat on although now it seems to be happening all the time whenever we hit a small bump. Anyone have any suggestions on how I could fix either one of these as they are driving me CRAZY?
