993 Driver window rattle - help!

[clapham993]

Guys

The driver window in my 993 has started to rattle really badly in its frame. At first it was barely noticeable &, if you put the window down then up it cured it. In the last few days it has got really bad.

Before I allow OPC to make free with the balance on my good friend Mr AMEX, does anyone know what might be causing this and, if so, how easy it is to fix?

Thanks

Peter
