Hi All--hope you can help because my dealer isn't returning my calls. I sent my 2005 Trailblazer in for a rattling/rubbing sound I get from the front windows when its cool/cold outside when I go over a bump or turn a sharp corner. They've replaced the weatherstripping twice and the service manager stated that it's "a common problem with 2005 Trailblazers that the techs are working on it". He now no longer returns my calls when I call to see what the status is. They gave me a rental 2006 Trailblazer and in all honesty, that one did it too, not as much though. Anyone else have this problem or a potential solution? I'm checking one more time on Saturday when it goes in for an oil change and hope I can get it resolved. any help is appreciated--I drive about 30,000 miles a year and its rather annoying in the New England winters!
