The fuse box in the F3 is located next to the battery in the engine compartment, and another one is inside the glove box on the left side of the steering wheel. The principle of a fuse is: 1. To connect the circuit in an electrical system; 2. Under abnormal conditions, the fuse acts as a safety protection component in the circuit, safely cutting off and protecting the circuit by melting itself. Taking the 2020 classic BYD F3 as an example, its body dimensions are: 4533mm in length, 1705mm in width, and 1490mm in height, with a wheelbase of 2600mm, a fuel tank capacity of 50 liters, and a minimum ground clearance of 170mm.

My F3 has two fuse box locations. One is in the engine compartment, visible when you open the hood, located at the front left corner near the windshield. The other is below the steering wheel on the driver's side, accessible by gently prying open the left cover panel. I'd advise against casually tampering with the one in the engine compartment yourself, as there are many wires and it's easy to make a mistake. I remember a friend's car had non-functioning headlights once, and it turned out to be a blown small fuse in the engine compartment fuse box – it was fixed after getting someone to replace it. If you're checking, it's best to wear gloves, and keeping a few spare fuses in the car is quite handy.

When I drove the F3 before, I checked the fuse box locations. The one on the left side of the steering wheel can be seen by crouching at knee level, and the cover can be pulled open by hand. The one in the engine compartment is next to the , towards the front windshield. Here’s a small tip for replacing fuses yourself: take a photo of the original position with your phone before operating, otherwise it’s easy to forget. Issues like a blown cigarette lighter fuse are quite common in older cars, so keeping a few 15A fuses in the car is quite practical. If you can’t find the exact location, try checking the manual or asking a mechanic at a repair shop to point it out.

The F3 fuse box is usually located below the steering wheel on the left side. You can see a removable plastic cover by looking down. If you need to find the one in the engine compartment, it's on the left side near the windshield. Remember to turn off the car's power and remove the key before replacing a fuse. Different fuses are responsible for different devices, such as 20A for headlights and 10A for the radio, so it's important to distinguish them clearly. It's recommended that beginners avoid operating the engine compartment fuse box in rainy weather to prevent short circuits.

I'm very familiar with the F3's fuse box. There's a small storage compartment-like cover panel near the driver's left leg area - just pry it open to reveal the interior fuse box. There's another one in the engine compartment near the battery, covered by a black housing. It's best to bring a flashlight when checking, as the fuse location diagram is sometimes printed on the inside of the cover. If you encounter issues like AC not cooling or power windows malfunctioning, this should be your first troubleshooting spot. Keep 5-6 spare fuses of commonly used specifications in the spare tire compartment for emergencies, especially necessary for long-distance road trips.

I've worked on quite a few F3 models. The fuse box locations are divided into two areas: the one under the steering wheel cover is the cabin fuse box, controlling interior electronics; the one in the front engine compartment is near the left radiator frame, managing headlights and such. Always use specialized pliers to replace fuses - don't pull them out forcefully as it can damage the slots. For older F3s, fuses tend to degrade more easily, so I recommend a comprehensive inspection every three years or so. If you notice any vehicle functions suddenly failing, there's an 80% chance it's fuse-related. Addressing it promptly can prevent more serious wiring issues.
