What Causes a Car Horn to Sound Quieter?

[DelReagan]

Here are the specific reasons why a car horn may sound quieter: 1. Poor internal contact: According to the working principle of the horn, if the contacts are not properly connected, the horn may sometimes work and sometimes not. Factors such as wet or damp contacts should be considered. 2. Poor plug contact: Sometimes, the contacts around the steering wheel may wear out due to frequent use, leading to poor connections. This can also cause the horn to sound hoarse. If this happens during rainy weather, combined with poor contact, the horn may sound quieter or even stop working. 3. Water damage to the crossover: If the terminals are found to be damp or even soaked in water, they should be dried promptly. Additionally, ensure the car doors are properly sealed to prevent the horn from sounding quieter after rain.
