My 14 v8v sounds like hard styrofoam rubbing against hard styrofoam from the plastic panel surrounding the inside of the rear window. I can pull down on the piece while driving and it stops the sound. Best I’ve come up with is stuffing a shop towel in the corners, but that only seems to fix it for a few days until it’s smushed (no Longer applying pressure against the plastic piece) and the very annoying sound returns. The piece is not loose or anything, and makes the sound from both top sides.

Any suggestions?

eta: have a photo but it seems unwilling to upload from my iPhone on mobile or full site

Bump. Nobody else has a very annoying squeaking from the rear windshield interior plastic panel? I can’t make it squeak manually, but while driving I can push up or pull down on the plastic and the noise stops completely. Just can’t figure how how to make it more permanent.

Finally got a pic to upload...See blue shop towels stuffed to temporarily prevent the noise. After a day the towels get compressed and the outward pressure stops and styrofoam squeaking resumes unless I push up or pull down on this panel while driving.

I cant get it to make the noise with the hatchback open or pushig on it myself, it only happens naturally when driving.

for all I know it may not be The panel but something else the panel puts pressure on.
