I brought it for this exact issue. Window just dropped when in down position. They found nothing and charged me 95.00 under my extended warranty. Three weeks later, it drops again. So I brought it back. And printed this forum, and handled to the service repair man. I wonder NOW what they will tell me. I hope they find the weld or whatever they couldn't find before. I am out of a car for a week at a time. This is ridiculous.
