Where is the car fuse box located?

Generally, there are two fuse boxes in a car. One is responsible for the safety of external electrical components, such as the ECU, windshield washer, lights, horn, ABS, etc., and is located in the engine compartment. The other is responsible for the normal operation of internal electrical components, such as the cigarette lighter, power windows, electric seats, and airbags, usually located on the left side of the steering wheel. More related details are as follows: 1. Purpose of car fuses: The official name of a fuse is "circuit breaker." The purpose of a car fuse is similar to that of a household fuse—it melts when the circuit current is abnormal and exceeds its rated current, acting as a protective barrier for the circuit. Automotive fuses can be broadly divided into two types: fast-acting fuses and slow-blow fuses. 2. Commonly used car fuses: high-current fuses and low-current fuses. The ones most commonly encountered are medium- and low-current fuses. Medium- and low-current fuses can be roughly categorized into blade-type fuses (including automatic fuse boxes and mini fuses), plug-in fuses, screw-in fuses, tubular fuse boxes, and flat-type fuses. Among these, the most commonly encountered are medium-sized ATO or small-sized fast-acting blade fuses. Blade fuses can handle small currents and short-duration pulse currents, such as those in headlight circuits or rear window defrosters.
As an ordinary car owner, I frequently check my car's fuses because their location is indeed crucial. In my Volkswagen, there are two main locations for the fuse box: one is in the engine compartment, right under the hood near the windshield—just lift the cover to see a bunch of small squares; the other is inside the cabin, hidden on the side of the dashboard below the steering wheel, sometimes requiring flipping open a panel. I remember once when the wipers stopped working, I first checked the fuse under the hood, found it was blown, replaced it with a new one, and fixed the issue. Different car models may vary: SUVs might have fuses in the trunk, while sedans usually place them inside—the safest method is to refer to the vehicle manual, which clearly marks their locations. If you can't find them, don't force it to avoid damaging the wiring; it's best to drive to a repair shop for help. For safety, avoid frequently pulling out or inserting fuses to prevent short-circuit and fire risks.
As a car enthusiast with some mechanical knowledge, I find fuse box locations aren't that mysterious. Usually when you pop the hood, there's a plastic box near the firewall marked with icons or text labels. Alternatively, inside the cabin - below the dashboard or behind the glove compartment - a simple push reveals it. In my Japanese car, engine bay fuses handle external components like headlights and fans, while interior ones manage windows and the radio. Brands vary: American cars may integrate them into door panels, European models prefer center console placement. Safety tip: always disconnect power before inspection, use a multimeter to check for blown fuses, and match color codes to amperage ratings. Side note: wiring degradation or aftermarket modifications often cause fuse trips. Regular contact cleaning extends lifespan, but complex issues warrant professional technician attention.
