What Causes the Squeaking Noise from the Sunroof Seal?
2 Answers
The squeaking noise from the sunroof seal may be caused by aging of the seal, which requires timely replacement. Definition of a Car Sunroof: A car sunroof is installed on the roof of the vehicle and effectively promotes air circulation inside the car, allowing fresh air to enter. Additionally, a sunroof can provide a broader view and meet the needs of mobile photography and videography. Benefits of a Car Sunroof: While opening the side windows can also facilitate air exchange, a sunroof changes the traditional method of ventilation. When the sunroof is opened, wind creates a flow of air that draws out stale air from the cabin. During high-speed driving, air flows rapidly around the car. When the sunroof is opened, an area of low pressure forms outside the vehicle. Due to the difference in air pressure inside and outside the car, the stale air inside is drawn out, achieving the purpose of ventilation and ensuring the cabin remains filled with fresh air.
Recently, there's always been a creaking sound when opening and closing my car's sunroof. After researching, I found it's mainly caused by aging and deformation of the rubber seals. Long-term sun exposure hardens and cracks the rubber components, causing friction with the window frame that produces strange noises. A mechanic at our local repair shop taught me to spray rubber protectant into the seal gaps, which temporarily alleviated the noise. If the rubber seals are severely deformed or the window frame is misaligned, a complete replacement might be necessary, along with cleaning out accumulated sand and leaves in the guide rails – once at a parking lot, I saw workers disassembling a sunroof and found three small stones stuck in the guide rails.
