In the E36 convertible (I have a 1996 328 convertible), since there are no upper frames on the doors, the power windows are designed in such a way that when you close the door, the window is supposed to go up by itself another 1/2" or so in order to make a firm seal with the top. Recently, the driver's side window on my car stopped doing this, and so doesn't completely seal with the top, which, as you can imagine, is no good when you're going down the highway, or when it's raining :). I can still raise and lower the window just fine, and the passenger side window still behaves properly. I'm guessing this means that whatever mechanism the window uses to determine whether the door is open or closed is stuck on thinking it's open, but I have no idea what that mechanism might be, or how to diagnose it. Any advice would be appreciated. Thanks,
