Mine used to make some noise too, then a friend of mine who's a body man showed me the top of the door wasn't fitting tight against the seal when closed. He opened the door and GENTLY flexed the top of the door in and " adjusted " the fit until it sealed tight. He positioned a small block of wood between the door and door frame to keep the door from closing and then bent the top door frame a bit at a time.
I have window visors too, for the exact same reason as Rhinoman. work great.
