Rattling Window

[DoDaniel]

I have a slight problem, although it is not major. Recently my passenger side window has been making a rattling noise, I think that it has become loose and will need tightening. This is all due to my mate slamming the door as hard as he can and then wondering why I get pissed at him. If he breaks the door or the window, then he will be paying for it.

Anyway, Is there any way to tighten the window as it is rattling quite bad now.

Thanks

remove the door trim and have a look , might be soming loose where it secures the window at the bottom
