Hey guys I was just wondering if anyone had some insight on this. I tried searching and didnt come up with anything. Well my window on the passenger side with the door closed when I start to roll it down it makes this "pop" sound. The pop sound is only when the window starts to move down. The window will go all the way down and come back up and then when I roll it down again it doesnt make the noise. If I wait a few minutes with the window up and the door closed and try to roll the window down it makes that pop once and its gone. If the door is open and I roll the window down there is no noise. I recently regreased the rubber seals on the top molding with shin-etsu grease. I dont think it is the regulator/motor since my window still opens and closes fine but idk. Any suggestions would be greatly appreciated. Thank you.
