Buzzing... argh!

[Captain Jack]

OK, having (nearly) sound proofed the door cards (they don't rattle as much), I now have another buzzing noise which I only get travelling over 60mph. And since half my journey to work is on a motorway, it's quite often. What really gets me is I have no idea where it's coming from. It sounds like it coming from inside the door somewhere but I can't locate the source. What's weird is it's only doing it at speed, so it must come from the outside somewhere.... I was thinking more of the door strip thingies or maybe the handle itself?

Any ideas? It's driving me up the wall!

try the holes under the triangular plastic bit that covers the mirror screws.
