What Causes the Zizzing Resonance Noise from Car Doors?
2 Answers
Reasons for zizzing noise from car doors during driving: The zizzing noise from car doors while driving is most likely caused by loose door hinges or noise from interior trim panels. If the door hinges are loose, the bumps encountered during driving can cause the doors to vibrate continuously, resulting in various abnormal noises. Additionally, poorly assembled interior door panels can also lead to noise. The specific cause of the noise needs to be determined based on actual conditions. Extension: Impact of tensioner pulley noise on the car: Tensioner pulley noise is usually caused by excessive wear of the tensioner pulley bearing. When the tensioner pulley has issues, the engine may experience timing misalignment and valve timing disorder, which can significantly affect the normal operation of the vehicle.
After driving for so many years, the most annoying thing is the zzz sound of the car door at high speed, like a little bug drilling in. The most common reason is the aging or wear of the door seal. When the rubber strip hardens or becomes fuzzy, the wind blows into the gap and causes vibration and noise. It could also be that the window glass is not installed firmly, with dust accumulated in the lifting track or loose clips, causing noise when the door is closed. Another possibility is loose wiring harnesses or lifting motors inside the door panel, which can vibrate even with loud music. It's not difficult to deal with. You can try applying some lubricant to the seal or lightly knocking on the door panel to listen for changes in sound. If the noise persists, it's recommended to check the seal and reinforce the internal components. After parking, regularly clear debris from the door grooves to prevent dust accumulation and looseness, which can save a lot of hassle.
