The solutions for door resonance noise are: 1. Clean the door sludge thoroughly and spray lubricant on the hinge parts; 2. Apply sesame oil or butter to the hinge parts; 3. Clean the dust around the windshield area; 4. Replace the door sealing strip; 5. Check if there is excessive dust inside the window sealing strip, causing friction between dirt and the glass; 6. Inspect the window regulator for any issues. The causes of door resonance noise are: 1. Hinges becoming stiff and producing noise; 2. Dust entering the windshield; 3. Aging of the door sealing strip; 4. Abnormal noise from the electric window lifting mechanism.
The door has resonance noise, let me share some experience. This is usually caused by aging door seals or loose door locks. I recommend first using silicone spray or lubricant on the door hinges and latches, which can quickly reduce friction noise. If the noise persists, check the wiring harness or small parts inside the interior panel and secure them with double-sided tape or zip ties. Another common reason is the door not closing tightly, and fine-tuning the door lock position can improve the fit. For older cars, the seals may be completely worn out, and new ones will need to be replaced. I've encountered this situation before, ignoring it will make the noise worse and worse, affecting driving concentration and even causing accidents due to distraction. So, during regular maintenance, have the technician thoroughly inspect the door structure—prevention is better than cure. Develop a habit of simply wiping the edges of the door after each car wash to ensure everything is tight.
