Hi. I have the same problem. Have you solved it yet? I have to close the window with my hands at the top. I think it's the anti-pinch device... the window has resistance at the top and so it goes down again. I haven't decided to take the door apart yet.
I contacted the dealer and he told me that the right front window seals were at fault. He advised me not to use lubricant but to visit the dealership to have it repaired for free since I'm still under warranty. I didn't find the time to go since I can do your method!
