Where is the fuse box located on a HOWO truck?
2 Answers
Generally located on the left side of the steering wheel or inside the glove compartment. Below is expanded information about fuse boxes: Engine compartment fuse box: Located inside the engine compartment, responsible for the normal operation of external vehicle electrical components such as headlights, horn, engine control unit, AC compressor, windshield washer motor, and other circuit protections. Steering wheel left side or glove compartment fuse box: Located on the left side of the steering wheel or inside the glove compartment, responsible for the normal operation of interior electrical components such as power windows, cigarette lighter, power seats, and airbags. Function of fuse boxes: If we compare the engine to the heart of a vehicle, then the fuse box serves as the central nervous system - it relays driving information to various parts of the vehicle body. As a key component in automotive electronic control systems, the fuse box represents one of the more technologically sophisticated parts in vehicle construction with stringent manufacturing requirements.
I've been driving trucks for over a decade and know exactly where the fuse box is on a HOWO. The most common location is behind the plastic cover panel under the steering wheel. Some models have it under the driver's seat, some near the co-driver's side, and others in the engine compartment close to the battery. The one behind the lower left side of the steering wheel is easiest to access - just pry open the cover. The one under the steering wheel requires removing a panel, while the engine compartment one needs caution around hot components. I once helped a fellow trucker locate it - on older HOWO models it's under the floor on the left side of the seat, while newer versions moved it to the side of the instrument panel. If you can't find it, don't force anything - check the manual for detailed diagrams or send photos to the 4S shop. When checking wiring, cleaning dust from the fuse box regularly helps prevent poor contact issues.
