The horn fuse in the Great Wall M4 is located on the positive line of the 12V accumulator. The original audio system is behind the main unit, and the speakers do not have separate fuses. The Great Wall M4 is a compact SUV with body dimensions of 3995 mm in length, 1728 mm in width, and 1617 mm in height, with a wheelbase of 2383 mm. In terms of power, the Great Wall M4 is equipped with a 1.5-liter naturally aspirated four-cylinder engine, delivering a maximum power of 78 kW and a maximum torque of 138 Nm. The engine reaches its maximum power at 6000 rpm and its maximum torque at 4200 rpm.

I've been driving my Great Wall M4 for almost three years now. Last time, the horn suddenly stopped working, and I was quite nervous at first, thinking the horn might be broken. Later, I checked the manual and figured out that the horn fuse is located behind the storage compartment on the driver's side. You need to open the storage compartment first, then carefully remove the small panel at the bottom to reveal a fuse box with about a dozen fuses inside. The one marked with a small horn icon is the one you're looking for, usually labeled as F20 or F25. I tried pulling out the old one to see if it was blown, and sure enough, it was, so I replaced it with a new one. The whole process took about twenty minutes, and the tools required were simple—just a screwdriver. This reminded me how important it is to regularly check the fuses, otherwise, if you encounter an emergency while driving and the horn doesn't work, it could lead to serious trouble. I recommend taking some time to check it yourself when you're free. The manual also has clear diagrams, and if you really can't find it, just take it to a repair shop.

As someone who frequently tinkers with cars, I've encountered many similar issues. The horn fuse for the Great Wall M4 is typically located in the fuse box under the hood or beneath the dashboard, specifically behind the driver's side storage compartment cover. You'll need to carefully open that black plastic cover, where you'll find strip labels indicating each fuse's purpose. The horn fuse is usually positioned towards the center, often labeled as F15 or similar. From my own experience, if the fuse blows, the horn stops working immediately, which could be caused by a short circuit or prolonged horn usage leading to overload. Replacing the fuse is straightforward - just find one with the same specifications, but remember to turn off the power first to avoid short-circuit risks. Regular checks on these components can prevent bigger troubles, especially during rainy or dusty conditions when they're more prone to failure. It's always wise to keep some spare fuses in your car.

I am the owner of a Great Wall M4 and just had the horn checked last week. The fuse is located near the storage compartment on the driver's side. Simply put, you just need to remove the storage compartment cover, and the fuse box is right behind it. The horn fuse is usually in the third slot of the second row, marked with a small horn symbol. It took me five minutes to find it, and replacing it with a new one did the trick. Remember, a non-functioning horn is very dangerous as it affects your ability to alert others when overtaking.

I really enjoy fixing my own car. Last time when the Great Wall M4's horn went silent, I immediately got to work checking it. The location is in the fuse box behind the storage compartment under the dashboard. You need to remove that soft cover panel and look for the fuse marked with the horn icon, usually red or blue in color. Only pliers and a new fuse were needed as tools, and it was done in ten minutes. During regular maintenance, it's recommended to check this as well, because the horn is used daily and can easily wear out the fuse, avoiding embarrassing situations on the road. Try DIY, it's simple, saves money, and builds skills.
