Chevrolet Colorado 2012-2022 fuse box and relay Diagrams
The Chevrolet Colorado (2012-2022) is a midsize pickup truck known for its versatility and capability. Its electrical system is protected and managed through fuses and relays, ensuring the smooth operation of various components.
The fuse box is located both in the engine compartment and inside the cabin. The engine compartment fuse box manages critical systems such as the engine control, headlights, and cooling fans. The cabin fuse box handles lower-power components like the infotainment system, power windows, and interior lights. If any circuit experiences an overload, the fuse will blow, cutting power to prevent damage.
Relays in the Colorado act as switches that control high-power systems, including the fuel pump, starter motor, and air conditioning system. These relays allow low-power circuits to operate high-current devices safely. If a relay fails, it can result in key components malfunctioning, such as the engine failing to start or the cooling fan not running.
Regular inspection and maintenance of the fuses and relays are essential for preventing electrical issues and ensuring that critical systems function properly in the Chevrolet Colorado.

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.
