What are the reasons for the New Sail's horn not sounding when locking the car?
5 Answers
New Sail's horn not sounding when locking the car: reasons and solutions are as follows: Locking horn function turned off: If the locking horn function is turned off in the vehicle settings, there will be no sound when locking the car. Horn malfunction: If the vehicle's horn has a problem, it will not sound when locking the car. Solutions: When the vehicle's horn does not sound when locking, it may be due to a horn malfunction or a system issue. You can first use the elimination method to check. If you are unable to perform the operation yourself, you need to take the vehicle to an after-sales service or repair shop to seek the help of a technician to solve the problem.
The car horn doesn't sound when locking. I've encountered similar issues several times. First, it could be a blown fuse. The fuse box in the new Sail is usually located under the steering wheel, making it easy to check and replace yourself. Second, there might be a problem with the locking system itself, such as a dead battery in the key remote or dirty/rusted contacts—cleaning them might help. Another possibility is that the horn itself is faulty; aging after several years of use is normal, especially in humid weather. Additionally, short circuits or broken wires are common causes, particularly in older cars where wiring harnesses can loosen and wear out, leading to poor contact. If you often park on the roadside, frequent vibrations might also cause issues. I recommend starting with the simplest solution—replacing the fuse—to avoid unnecessary expenses. If that doesn’t work, consult a professional shop to ensure safety. Finally, during regular maintenance, ask the mechanic to check the locking system to prevent such problems.
As a veteran driver with over 20 years of experience, I've seen this kind of thing happen all too often. A car horn not sounding when locking is mostly caused by minor issues. Something as simple as a blown fuse - the fuse box location in the new Sail isn't hidden and can be easily opened to replace one, costing less than ten yuan. If it still doesn't work after replacement, consider whether the horn unit has been waterlogged or aged and cracked - a common issue with this model. Wiring problems like loose connections or accumulated dust can also cause failures over time. A mechanic can quickly locate the break point with a multimeter. As a last resort, check the key battery and door sensors which are linked to the locking system - sometimes cold weather causes batteries to discharge too quickly. I recommend not delaying repairs as it may affect other functions. Safety first - getting it fixed at a roadside stall for ten yuan is both economical and effective.
If the horn doesn't sound when locking the new Sail, I reckon it's most likely related to the electrical system. For instance, a fuse might have blown due to overload—check the fuse box in the engine compartment and try replacing it with a new one. If that doesn't work, it could be that the internal coil of the horn is burnt out or the contacts are corroded; you'd need to take it apart for repair or replacement. Another possibility is a wiring issue, like a loose plug or damaged wiring harness causing an open circuit that prevents current from passing through. Additionally, if the key remote's signal is weak, it might just be that the battery is running low—replacing the battery could solve the problem. Faults in the locking control module are rare in some models, but shouldn't be overlooked. It's best to take the car to a small shop for a comprehensive check to ensure there are no major issues. It's inexpensive, simple, and quick.
The car lock horn suddenly stopped working, and I'm particularly concerned about safety because it helps us confirm the car is locked, preventing theft risks. There are many common reasons, including a blown fuse. The fuse in the new Sail is easy to check and can be handled by yourself—replacing it costs very little. Or the horn itself may have aged or been damaged, especially if the car is often parked outdoors exposed to wind and sun for a long time. In terms of circuits, a broken or short-circuited wire can be detected with a multimeter to find the issue. Don't overlook the key battery—if the battery is low, the horn's signal reception may be poor, causing it to malfunction. It's recommended to check immediately. If you can't fix it, go to a repair shop right away—don't risk driving to avoid other systems malfunctioning as well. During regular maintenance, remind the technician to check this part for added peace of mind.
