What are the reasons for the Volkswagen Sagitar's horn not working?

[MaliaMarie]

Introduction to the reasons why the Volkswagen Sagitar's horn is not working is as follows: 1. Open circuit problem in the horn power line: You can check the line to see if it is clear or broken. If it is, just reconnect the line. 2. Poor contact of the horn button: While pressing the horn switch, listen to whether the relay is engaged. If the relay is engaged regardless of whether the horn sounds or not, it is generally a problem with the horn or the line. If the relay is not engaged when the horn does not sound, it indicates poor contact of the horn button. Just repair the poor contact point. 3. Relay contact burning or excessive gap: This leads to an open circuit in the horn's magnetic coil. In this case, it is recommended to go to a 4S shop for professional repair.
