The Discovery 4 has two fuse boxes. The interior fuse box is located behind the glove compartment on the passenger side, while the engine fuse box is situated in the engine compartment next to the battery. Functions of the fuse boxes: The interior fuse box manages the electrical components inside the vehicle, such as the power windows, airbags, power seats, and cigarette lighter. The engine fuse box is responsible for the fuses of external electrical components, including the engine control unit, horn, windshield washer, ABS, and headlights. Introduction to fuses in the fuse box: Automotive fuses are a type of current fuse. When the circuit current exceeds twice the rated current of the fuse, it will blow within seconds to protect the circuit. Always replace fuses according to the rated current value specified on the fuse box cover, and never use a fuse with a higher rated current than recommended.

As a long-time Land Rover owner, I've found that the fuse box for the Discovery 4 is typically located in two main areas: one is in the engine compartment, near the left side of the battery, covered by a black plastic box that's a bit tight but clearly labeled once the hood is lifted. The other location is inside the vehicle, usually in the footwell under the front passenger seat, accessible by lifting the carpet or trim panel. I recommend checking the interior location first, as it's easier to access and safer, especially when dealing with quick fixes like headlight failures or AC malfunctions. The exact position may vary slightly depending on the model year—for example, earlier versions are in the left footwell, while newer models might be closer to the center console. Always ensure the engine is off and the power is disconnected before handling to prevent electric shock, which is crucial. Spare fuses are often stored in the vehicle's toolkit, so it's wise to keep a few on hand for emergencies. Familiarizing yourself with these locations can make routine maintenance much more convenient.

I've driven my cousin's Discovery 4 a few times, and the fuse box is mainly located near the battery in the engine compartment or under the passenger footwell inside the car. The one in the engine compartment is at the front left corner after opening the hood, usually protected by a plastic cover that needs to be carefully lifted. The one inside the car is easier to find—just lift the carpet to see the metal box. Last time my car's electronics had issues, that's where I fixed it. The location doesn't vary much across different model years, and simple tools like a flashlight can help with inspection. I also noticed the design considers ergonomics, making it easier to access compared to some older cars. Remember to turn off the engine before checking—safety first. Knowing the location helps quickly address minor issues, saving unnecessary trips to the repair shop.

As a Land Rover owner who frequently interacts with the vehicle, I am very familiar with the location of the Discovery 4 fuse box: it is generally near the battery in the engine compartment and in the footwell area on the passenger side inside the car. Simply lift the corresponding cover or carpet to access it. The location is conveniently accessible, and it is recommended to check after turning off the engine. Spare fuses are often stored in the toolbox for emergencies. The position is stable across different configurations, making it suitable for DIY maintenance.
