Why doesn’t the car horn sound when it’s cold?

It is caused by poor grounding of the cross shaft in the steering wheel. It is caused by cold weather, which leads to poor conductivity of the cross shaft, causing the speaker's power cord to be unable to be grounded and unable to form a path. Waiting for the vehicle to heat up, this fault will disappear and you can handle it yourself. The solution is to short-circuit the steering shaft, which requires the use of copper wire. The horn of a motor vehicle is an audio signal device. When the motor vehicle is driving, the driver of the motor vehicle sends out the necessary audio signal according to needs and regulations to warn pedestrians and other vehicles on the road to pay attention, ensuring traffic safety, and at the same time also It can be used to urge traffic and transmit signals, and is equipped on every motor vehicle.
