.....ok I think I have located the source of the wind noise/draft problem that Ive been having.
It seems as if the passenger door has dropped slightly and isnt sitting flush with the rubber door seal.
Its the top bracket/hinge that has play in it and is allowing the door to hang slightly lower.
My question is - how do I fix it? Is it a case of finding a replacement hinge or can I undo it/re-align it?
Thanks for your help guys.
