Hi everyone, interested if anyone else has had this happen and if they bothered fixing it (if it is important to fix at all).
I usually park in my garage with my windows down a bit to allow some air circulation. I put my window up today and a piece of window "fuzz" popped out, stuck to the glass, as I raised the window. It appeared frozen onto the window (its been unusually cold here last few days).
Looks like a piece of a bigger strip that broke off. I'm hoping that enough of it remains to stop the glass from being damaged. I guess I could replace this strip if I remove the interior panel? I would probably do a speaker upgrade at the same time. I didn't force the window up, it went up with ease.
Its a 13 FRS with 43000km. I suspect its a bit brittle due to age combined with being frozen to the glass.
Update: Looks like the part is SU003-01616, "Glass Stabilizer", OUTER. There have the same part number regardless of side. It appeared stuck to the outside of my window so I'm assuming its the outer one.

Part #6 in this diagram. Now the question is can I run without it, or should it be replaced?
