I have lexus RX300 2002. My driver window squeaks, "no problem" i said, "just need some wd-40 silicone spray", right?

Well, after spraying, the window motor now struggling to move the window up and the squeak gotten worse, MUCH worse. WTF lol . Did i do something wrong here? I only sprayed the rail and the rubber seals.

Did the squeak get worse or is there not enough power to move your rusted or ceased parts?
Try actually glass polish on glass you never had a cleaner set of windows before. WD will lube and is fine for cleaning glass but it isn't clean until it is polished.

The motor is still good and still has good power, open and closes like passenger windows, it has a little rust but i think it's not major.

The squeak that actually gotten worse after the spray, to a point that at hot summer the glass stuck, when i blow the ac to the windows it didn't stuck anymore (basic physics lol), so i know it's the side rubbers or rails that squeaks.
It's just doesn't make sense that it gets louder.

So how do i polish the glass? Should I remove the windows, rails, etc just to get it polished? Or simply polish the interior and exterior side?

I'll maybe send the video, it squeaks horribly in a cold day
