Why is the Volkswagen Lavida's horn not working?
1 Answers
The reasons why the Volkswagen Lavida's horn is not working include poor contact of the horn's wiring, a blown fuse, or a malfunction in the horn's control unit. The analysis of the Lavida's horn not working is as follows: 1. Check if the live wire has power: Use a screwdriver to scrape the battery terminal of the horn relay against a ground connection. If there is no spark, it indicates a short circuit in the live wire, and you should check for any open circuits in the wiring between the battery fuse and the battery terminal of the horn relay. 2. If the live wire has power: Then use the screwdriver to connect the "battery" and "horn" terminals of the horn relay. If the horn still does not sound, it indicates a fault with the horn itself. If the horn sounds, it indicates a fault with the horn relay or the button. 3. Press the horn button and listen for any sound inside the relay: If there is a "click" sound (indicating the contacts are closed), but the horn does not sound, it suggests that the relay contacts are oxidized or burnt. If there is no "click" sound from the relay, use the screwdriver to short the horn button terminal to a ground connection. If the relay contacts close and the horn sounds, it indicates that the button is oxidized, rusted, or dirty, causing poor contact. If the relay contacts still do not close and the horn remains silent, it indicates a short circuit in the relay coil.
