Plastic noise

mmcmilan

When braking or accelerating or when hitting pothole I hear plastic noise (like when someone pack walmart plastic bags) from either driver front door panel (or insulation around door) or pillar between front and back door on driver side only. I hear same kind noise but much lower noise when pulling up window (only when it reaches top, not all the way...). It is only driver side and not passenger side. Anyone has any kind of idea how can I determine what exactly it is? And eventually how to fix it? It drive me nuts, other than that car is so quite (specially with my Defender tires), that any kind of noise is driving me crazy... Please advise if you have any idea what can I try...

I think you'll have to take the door panel off and operate the window and look around in there.
