Hello! I am trying to replace the vent glass on my 2018 Subaru Forester (driver side). I was able to get the door panel off, but can’t get the new window to slide into place correctly. My guess is that the piece separating the vent glass from the window piece that rolls down needs to be removed, but I can’t figure it out and scouring the internet hasn’t proved very helpful either. I’m not a car person at all, so any and all suggestions are welcome!
