Rattle from rear glass area?

[brett_g]

I've noticed a rattle that seems like it comes from the engine bay area; It seems to stop once things heat up, but is fairly persistent. My OCD ears tell me it is coming from the assembly on the cabin side of things back there. Has anyone else noticed/found the causation?

I have, quoting myself from another thread:

It might be in the interior. Back window, bottom edge. You can wedge you fingers between the glass and trim. Try having your passenger pull on the trim and see if it does something to the sound. There’s some foamy like blocks in there, probably to insulate the trim from vibrations. Sounds like they are instead rubbing onto something, like rubbing styrofoam together.
