The Chevrolet Corsica (1987-1996) was a popular compact sedan known for its practicality and affordability. Its electrical system, like all vehicles, relies on fuses and relays to protect and manage various components.
The fuse box in the Corsica is typically located under the dashboard on the driver’s side. This fuse box controls a variety of electrical systems, including the headlights, wipers, radio, and power windows. If any of these systems experience a power overload or short circuit, the corresponding fuse will blow, cutting off power to prevent damage.
Relays in the Corsica control higher-power systems such as the fuel pump, starter, and cooling fans. Relays act as switches, allowing low-power circuits to control high-current systems. If a relay fails, the associated system might not function properly, such as the engine not starting due to a faulty starter relay.
Proper maintenance of the fuses and relays is important for the Corsica’s longevity, ensuring that electrical issues are prevented and critical systems remain functional.

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.
