Hi, my car developed an unbearable rattle near the passenger HVAC. I believe I have it diagnosed down to the trim piece that goes over the HVAC vent, that has contact with the door when closed. I removed the dash pieces and the airbag cover, and it still made the noise. This piece seemed to make a similar noise when I tapped on it. So I pulled it off, and of course the 2 metal clips came off so I'll have to fish them out or buy 2 new ones (anyone have part #?). But another thing I noticed is there are 3 slots, but the trim piece only had two protruding areas where you can attach metal clips. The 3rd area does not look the same...it does not look like it takes either the metal or white clip. So either it's a weird design, or that broke off. Any ideas? The noise drives me nuts, I'm real sensitive to it for some reason.
