Some Mercedes-Benz C300 owners report experiencing issues with window regulators that can result in multiple windows remaining down simultaneously. Common symptoms of a faulty window regulator include windows moving slowly, making unusual noises, or getting stuck in one position. Additionally, malfunctioning window motors may contribute to these power window problems. The wear and tear of window regulator gears and hinges due to friction from the motor can also lead to operational issues.
