What is the reason why the horn does not sound when locking the 2013 Lavida?

The reason why the horn does not sound when locking the 2013 Lavida is that the horn's grounding wire has poor contact and has become loose. Since the horn vibrates continuously during operation, it is normal for the wiring to become loose. Check whether the horn's fuse is damaged. The car has multiple horns, and when multiple horns work simultaneously, the current can reach 15A or even above 20A. If the horn button is used to directly control the current, the high current will quickly burn out the horn button, hence a horn relay is used. Taking the Lavida 2013 Classic 1.6L Automatic Fashion Edition as an example: it is a compact 4-door 5-seater sedan under SAIC Volkswagen, with a length, width, and height of 4608mm, 1743mm, and 1465mm respectively, a wheelbase of 2610mm, equipped with a 6-speed automatic manual transmission, and a top speed of 174 kilometers per hour.

As a seasoned driver with over a decade of experience, I've encountered many instances where the car horn doesn't sound when locking the vehicle. In the 2013 Lavida model, there are several main reasons for this issue: a blown fuse is the most common problem, caused by circuit overload or aging; the horn itself may be damaged, such as from water corrosion or long-term wear and tear; loose or short-circuited wiring connections, where corroded or detached connectors interrupt the signal; additionally, a malfunctioning body control module or the horn alert function being turned off in the settings could also be the cause. I recommend first checking the manual to locate the fuse box, usually found in the lower left corner of the dashboard, to see if the horn fuse is blown. If that's not the issue, inspect the horn wiring connections in the engine compartment for stability. Avoid tampering with the wiring yourself, as it can lead to further complications. It's best to take the car to a professional repair shop for diagnosis and handling to prevent any safety vulnerabilities.

Bro, I've encountered the same issue with the horn not sounding when locking the car on the same model. There could be several reasons. A blown fuse is the prime suspect—it trips when the circuit is overloaded. The horn unit itself might be faulty, possibly due to poor contact or damaged internal coils. Wiring harness issues like oxidation, disconnection, or loose connections could also be the culprit. Additionally, the settings in Volkswagen cars might have accidentally turned off the alert sound. I recommend popping the hood to locate the small horn, manually shaking the wires to check for looseness, or trying the reset function with a spare key. If you can't figure it out yourself, just head to the repair shop—they can pinpoint the issue with their tools. Don't delay, as it might lead to misunderstandings.

Common causes of no sound from the horn include fuse failure or horn damage. Broken wires, loose or corroded connections can lead to signal loss; faulty body control module causing control failure; accidentally turning off the alert tone function is also common. First, confirm the fuse location and check its status in the fuse box diagram, then test the power supply voltage to identify the issue. If voltage is insufficient or the control circuit is malfunctioning, professional inspection is required; if voltage is normal, the problem lies with the horn and it can be replaced. Avoid adjusting complex components yourself and seek assistance from a repair technician.
