Chevrolet Equinox 2005-2009 fuse box and relay Diagrams

The Chevrolet Equinox (2005-2009) is a midsize SUV known for its spacious interior and practicality. Its electrical system is protected and controlled by a network of fuses and relays, which ensure proper functioning of various components.

The fuse box in the Chevrolet Equinox is located in two main areas: under the hood in the engine compartment and inside the cabin, often beneath the dashboard on the passenger side. The engine compartment fuse box manages high-power components such as the engine, cooling fans, and ABS system, while the interior fuse box handles lower-power circuits like the radio, power windows, and interior lights. Each fuse is designed to prevent electrical overloads by breaking the circuit if an issue arises, protecting the associated system.

Relays in the Equinox are essential for controlling high-current components, such as the starter motor, fuel pump, and air conditioning system. These relays act as switches, allowing low-current circuits to control high-power devices efficiently and safely. Regular inspection and replacement of faulty fuses and relays are important to maintain the vehicle’s electrical integrity, ensuring reliable operation of its systems and avoiding potential malfunctions.​

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.
