First problem. The window doesn't close correctly. It closes perfect until it is about 1 or 2 cm from the top then it seems to get caught on something and goes off the track and doesn;t seal correctly. The hright side ends up barly going to the seal as the left side is still exposed. In the pic below the yellow line represents the top of the window.
And two, there is this brown crap that seems like rust, but I don't see any metal. This is the driver side front window, the one between the window that rolls down and the windshield. idk what it is or how to fix it.
