Windshield problems of the 2006 Ford F-250

2006 Ford f250 pickup. On 1/14/07, I noticed that the rubber seal around the windshield was beginning to lift from the vehicle body (near the top of the windshield). I took the vehicle to my dealer who had a windshield professional inspect the rubber. On 1/23/07, I was notified by my dealer that the windshield professional glued down the lifted portion and that if there were any additional problems, it would not be covered by the manufacturer's warranty. Nothing has been altered on the vehicle to cause this. It is a manufacturer defect and Ford is claiming that it was damaged during usage. Through further research, I learned that Ford crown victoria's have a similar problem that resulted in a service bulletin. I am demanding that the entire windshield assembly (and seal) be replaced under warranty.
