Auto Air Conditioning & Heater Repair: Pontiac Montana windnoise, antenna mast, window pillar


Question
I have a 2004 Pontiac Montana and when I'm driving on the highway, 70 mph or so, if there is a crosswind, I get a noise that seems to be coming from the passenger side windshield post.  I think wind is getting inside the post between the windshield and the door.  i cannot seem to find exactly where.  Have you seen any service bulletins on similar problems or do I have the freak wind problem?

Answer
What I do to find out if it is coming from where you think it is:

Take a piece of cardboard and tape it across the space between the door frame and the door and drive the vehicle and see if it goes away.

I had a similar noise that drove me nuts for almost an hour. What it was was the air was whistling between the antenna mast and the window pillar because the owner put on his own antenna and placed it to close to the pillar post.
