What's wrong with honking the car horn in cold weather?

There is a phenomenon that the horn changes its sound in winter, so the foundation must be related to the weather. However, most of them are related to its own quality. For example, if there is something wrong with the speaker, it will change the sound or say no. You can check it in the physical store.

Poor contact of electromagnetic coil terminals: some terminals of electromagnetic coil enameled wire in the horn are connected by aluminum rivets, and the welding is unreliable. However, if the insulating paint on the end enameled wire is not cleaned or the rivet is not reliable, it will easily lead to the failure of the virtual joint and lead to the poor work of the horn.

The reason why the horn doesn't ring:

The main line fault is virtual connection, such as loose horn plug terminal, ablation of relay contact, poor contact of horn switch at steering wheel, etc. However, many horn failures, especially in winter, are mostly caused by the horn itself.
