Learn about Daewoo Leganza 1999-2002 fuse box and relay’s locations, functions, and maintenance tips for optimal vehicle electrical system.
The Daewoo Leganza (1999-2002) is a midsize sedan designed with a focus on comfort and affordability. It features a sleek, rounded body style, with a four-door sedan layout that emphasizes spaciousness and practicality. The Leganza is equipped with modern amenities for its time, such as power windows, air conditioning, and a sound system, making it a competitive option in the family sedan segment.
The car’s electrical system plays a crucial role in maintaining these features, and the fuse box and relay are integral components of this system. The fuse box is typically located in the engine bay or under the dashboard, managing key electrical functions like lighting, power seats, and the radio. Relays are essential for regulating higher-powered systems, such as the fuel pump and the air conditioning. Proper maintenance of the fuse box and relays ensures the continued functionality of the Leganza’s electrical systems, preventing issues like blown fuses or malfunctioning relays that could disrupt daily driving.

WARNING
- Never replace a fuse with one that has a higher amperage rating.
- A fuse with a too-high amperage could damage the electrical part and cause a fire.
- On no account should fuses be repaired (e.g. patched up with tin foil or wire) as this may cause serious damage elsewhere in the electrical circuit or cause a fire.
- If a fuse blows repeatedly, do not keep replacing it. Instead, have the cause for the repeated short circuit or overload tracked and fixed.
- Terminal and harness assignments for individual connectors will vary depending on vehicle equipment level, model, and market.
