The Chevrolet Malibu (2004-2007) is a mid-size sedan known for its practicality and comfort. Its electrical system is integral to the vehicle’s operation, with the fuse box and relays playing key roles in managing and safeguarding various electrical circuits.
The fuse box in the Chevrolet Malibu is typically found in two locations: one in the engine compartment and another in the interior, usually on the driver’s side, near the dashboard. The engine compartment fuse box handles high-power components, such as the engine, ABS, and cooling fans, while the interior fuse box manages accessories like the radio, power windows, and interior lights. Each fuse protects its circuit by disconnecting the power if there’s an overload or short circuit, preventing damage to the vehicle’s electrical components.
Relays in the Malibu act as switches for high-current systems, including the starter motor, fuel pump, and HVAC blower motor. These relays enable low-current circuits to safely control high-power systems, ensuring the car’s electrical system operates efficiently. Regular maintenance of the fuses and relays is essential to avoid electrical issues and ensure that the Malibu continues to perform reliably.

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.
