What Causes Plastic Interior Trim to Make Abnormal Noises in Cars?

[LaGrant]

Generally, abnormal noises from plastic interior trim in cars mostly occur during cold winter weather when the material becomes harder and may produce slight rattling sounds. Here are some additional details: 1. Adding rubber strips to reduce noise: You can place a layer of felt strips in the gaps, or install rubber strips between the dashboard and the windshield to minimize some of the noise. In summer, when it's generally hot, the noise tends to be less noticeable. 2. Things to note: It's also important to be aware that repeated disassembly and reassembly of interior components can lead to noise. Additionally, check if there are any loose wiring harnesses or small parts that may have fallen off. To address the issue, first identify the source of the noise before deciding on a specific solution.
