2 Answers
Solutions for car sunroof resonance noise: 1. Use sealant to bond the rain deflector; 2. Replace the rubber seal; 3. Disassemble the sunroof components and add soft padding. The car sunroof is installed on the roof and can be categorized into: sliding-out type, built-in type, built-in flip-up type, panoramic type, and curtain type. Functions of a car sunroof: 1. Increase lighting: Opening the sunroof on cloudy days or when photographing the car interior can enhance the light intensity inside the car; 2. Reduce wind noise: Opening the sunroof while driving can reduce wind noise and improve driving comfort; 3. Rapid cooling: Opening the sunroof and turning on the air conditioning can quickly lower the temperature inside the car.
My car's sunroof used to buzz loudly at high speeds, which was really annoying. I looked it up online and found many car owners facing similar issues, mainly due to resonance causing loose mechanisms or dirty tracks. I fixed it myself: first, I cleaned the sunroof tracks with a soft cloth dipped in water to remove dust and debris; then, I sprayed some sunroof-specific lubricant into the track grooves to make the glass slide smoother; finally, I checked if the screws were loose and gently tightened a few key connection points with a wrench. After the fix, the resonance noise was much reduced. If DIY doesn't work, it's recommended to visit a 4S shop to check if the sealing strips have aged. Regular sunroof maintenance can prevent noise issues—simple cleaning once a month is enough.
