How can I fix the interior panels that rattle. Little clip is broken, but that is cheap and would probably break again, so am looking for other options. Thanks.

 

Every one of my four doors had loose panels. I pulled all four, repaired all broken clip mounts with epoxy and picked up new clips at Napa. No rattles now.

 

I made this video a little while back. May be of some help.

 

Worse comes too worse, pick up some black vehicle interior screws, Predrill a small hole with a bit a little smaller than the screw, set screw , no more rattles or fighting broken clips and panel is easy to remove next time problem solved.

 

I hope GM designers have subscribed the thread. IMO worst thing about Blazers is the interior. Not only that it rattles (wrong material selection?). I wanted to airbrush the dash that was worn off here and there. While picking a paint I've realized all the panels are in different hue. Dash does not match door panels. Door panel handle does not match the door padding. Forget the pantones listed to the vehicles. They just won't match!

 

I had this rattle in the b-panel behind my ear when I am stopped at a light that wuz fixin to drive me crazy. Its right around where the seat belt comes out. I just give a little push there and it will stop but as soon as I let up it starts up again.

I pulled the plastic molding back. The only thing holding it on are the top seat belt bolt (used a 1/4" hex wrench on a cheater bar to break it free) and the clothes hook. The other contact surfaces are along the edges of the molding where it fits over the rubber on the frame but the buzzing was more of a plastic-on-plastic sound. There is some dynamat looking stuff glued inside the molding but that is just general soundproofing I think.

Then, bingo. At the bottom of the molding, under the hole where the seat belt comes out, I see a plastic clip with three supporting buttresses. Across from that is a rectangular hole where the clip fits... and just above that hole are three places where the plastic buttresses on the clip have rubbed deep marks into the plastic with each vibration. see pic.

So I stuck a piece of foam insulation on the marks, and as long as I had it out glued a few other pieces around. Buttoned it up and took her our for a test spin. No more BZZ BZZ BZZ.. I love driving again.

On edit: 18 months later, there is some buzzing coming back. Maybe foam is too lightweight for this
