The Chevrolet Lumina (1991-1994) is a mid-size sedan and coupe, popular for its spacious interior, comfortable ride, and straightforward design. Available as a four-door sedan or two-door coupe, the Lumina is designed for family-friendly utility and commuter comfort. Known for its reliability, the Lumina is equipped with essential features for its time, such as power windows, air conditioning, and basic safety options.
The electrical system of the Lumina, which powers these features, relies heavily on the fuse box and relay system. The main fuse box is typically located under the dashboard on the driver’s side, while an additional fuse box may be found in the engine compartment.

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.
