Where is the horn relay of BYD F6 located?
3 Answers
BYD F6 horn relay is located in the fuse box behind the left side panel of the driver's compartment. When the horn button is pressed, current flows through the circuit to the electromagnetic coil of the horn relay. The coil then attracts the movable contact switch to close, allowing current to reach the horn. Here are more relevant details: During daily driving, car horns often malfunction or fail, mainly due to the following reasons that require attention during operation: 1. Prolonged overload driving of the horn: The horn may burn out due to overheating as the coil temperature rises, causing certain structural components to melt, crack, or burn out. Under normal use, the coil temperature can reach 180°C, and the consequences of improper use can be imagined. 2. Mechanical failure: Overdriving the horn causes the diaphragm to move beyond its range and separate from the coil, or the coil to separate from its seat. The folded edge of the diaphragm or the horn's suspension may tear. Any of these situations can lead to horn failure. When the folded edge or suspension is torn, the coil will rub because the diaphragm assembly can no longer be properly suspended in the center. Small cracks may not be noticeable at first, but over time, as the cracks enlarge, the horn will eventually fail. 3. Horn failure may also result from a combination of the above two factors: For example, if the amplifier suddenly outputs a large instantaneous energy (such as a sudden increase in volume), the horn will vibrate intensely, causing the coil to move out of the magnetic gap. When it tries to return, misalignment may prevent it from returning to its original position.
The BYD F6 horn relay is usually located in the fuse box in the engine compartment. I just repaired my old F6, and the position is right in front when you open the hood—there's a black box. Open the lid, and you'll see a bunch of relays and fuses. Which one is for the horn? The manual or online diagrams usually have it labeled as "horn" or with a specific number. Replacing it is simple: first, turn off the engine and remove the key, then use a tool to gently pry open the clips and replace the relay. Remember to check the fuse—it often burns out, and loose wiring can also cause the horn to stop working. Be careful with the wires when working on it yourself—safety first. If you're unsure, ask a car-savvy friend for help. Fixing the horn not only saves money but also improves your DIY skills, making driving more reassuring. Remember to maintain it regularly to extend its lifespan.
I once had the same issue with my BYD F6's horn not working – it was really frustrating, especially at intersections where silence could be dangerous. The relay is located in the fuse box under the hood, easily visible once you pop off the plastic cover. It's usually positioned in the area ahead of the driver's seat, lined up among small square components. Don't yank them randomly; refer to the manual to identify the horn relay slot. If it's faulty, replacing a new one costs just tens of RMB, saving you garage expenses. I recommend routine pre-drive checks, like testing the horn after ignition. This is about driving safety – don't wait for an accident to act. I keep some tools in my car for quick emergency fixes; older cars demand diligent maintenance. Prevention beats repair.
