Does anyone else have a problem with a lot of noise coming from the driver side door when your going over bumps? I hear a high pitched squeak which I think is the mirror (i also hear it when i close the door) and I also hear some clunking inside the door panel.
Not exactly sure if this is the same, but when it's colder out where I'm at, I'll get a squeak on my car in kind of the same general area. Mine comes from the driver's side and the point where the dash plastic meets the pillar arm plastic. You can see where they rub against each other as the plastic is a little dusty in this area. I've just learned to live with it as it only happens when the temperature get colder, then when it gets too cold, the car goes into storage.
I had the same "A" pillar squeak as well and found it to be the metal clip that is attached to the plastic pillar cover that clips into the metal pillar. I fixed it by covering the part of the clip that pushes into the metal pillar with a piece of vinyl (electrical) tape and then pushed the clip into the pillar. No more squeak any time of the year.
