Chevrolet Caprice 1994-1996 fuse box and relay Diagrams
The Chevrolet Caprice (1994-1996) has a dependable electrical system that uses fuses and relays to power essential components. The fuse box is located under the dashboard and manages systems like the headlights, power windows, radio, and interior lighting. Each fuse protects specific circuits by interrupting the power flow if there’s an electrical overload, preventing damage to the wiring.
The relays in the Chevrolet Caprice control major functions, such as the starter, cooling fans, and fuel pump. These relays act as switches, allowing smaller electrical currents to control larger systems. If a relay, such as the fuel pump relay, fails, it can cause starting issues or stop the fuel pump from functioning correctly.
Regularly inspecting and maintaining the fuses and relays ensures the Chevrolet Caprice’s electrical system continues to function reliably. A blown fuse or a faulty relay can lead to malfunctions, but timely replacement keeps all critical systems running smoothly.

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.
