My drivers side window is not stock, the guy I bought it from replaced it, because someone broke it to steal some stuff out of the car. Now, when I close the door, it stays sealed, nice and tight. BUT, if I roll the window down and then roll it up, there is basically air flowing in hard next to my ear, it is almost like the window is cracked. I can stick my finger in between the window and weather stripping and almost outside I would imagine. Is this due to needing weatherstripping replaced? or could this window be crap, since it is aftermarket?
