What to Do When a Car Horn Gets Waterlogged and the Sound Becomes Muffled?

[SanAutumn]

Replace the horn. The vehicle horn is an electronic component, and water ingress can affect its performance. Even after repair, it may not return to normal functionality, so replacement is the only option. During the use of motor vehicles, it is essential to prevent water from entering components, as severe cases can damage other parts. Here are some methods for dealing with severe water ingress in the horn: 1. Use a Hair Dryer: For externally accessible horns where a hair dryer can reach, you can use the dryer to heat the interior, accelerating water evaporation. Once the water evaporates, the sound should return to normal. 2. Disassemble and Clean: Remove the horn and thoroughly clean out the water inside. Since most vehicle horns are located inside the bumper, removing the bumper is often necessary to access the horn. Therefore, disassembly and cleaning should be done at a professional 4S shop. 3. Replacement: If the horn is damaged due to severe water ingress, the only solution is to replace it.
