What are the causes of car window rattling noises?

[VanCayden]

Car window rattling noises are caused by: 1. Aging of glass sealing rubber strips: Often, the aging of rubber strips is the reason for resonance rattling noises in car windows; 2. Debris in the window glass guide rails: Dust and particles can easily be brought into the gaps of the sealing strips in the window slots during the process of raising and lowering the glass, which can easily cause vibration and rattling noises in the car windows; 3. Loose internal parts of the dashboard: Loose fastening screws or misaligned components inside the vehicle dashboard can also lead to resonance rattling noises in the windows. When the engine is idling, the engine's vibration causes the entire body to shake, leading to dashboard tremors and resulting in rattling noises. This may also be closely related to whether the screws were tightened sufficiently and installed correctly during the manufacturer's assembly. To completely eliminate the fault, it is necessary to remove the dashboard for inspection and repair.
