Learn about Chevrolet Prizm 1998-2002 fuse box and relay’s locations, functions, and maintenance tips for optimal vehicle electrical system.
The Chevrolet Prizm (1998-2002) is a compact sedan known for its reliability, fuel efficiency, and straightforward design. Built on the same platform as the Toyota Corolla, the Prizm features a clean, functional exterior and a practical interior layout. Its single body style—four-door sedan—caters to drivers seeking an affordable, efficient daily commuter with comfortable seating for up to five passengers.
The Prizm’s electrical components, from the lighting to the audio system, rely on well-organized fuse boxes and relays for proper function. The main fuse box is located under the dashboard on the driver’s side, while a secondary fuse box can be found in the engine compartment. Relays, responsible for high-power functions like the fuel pump and cooling fans, are positioned near these fuse boxes. Routine inspection of these components is essential to keep the Prizm’s electrical system operating smoothly and prevent potential issues.

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.
