The Chevrolet Silverado Mk2 (2nd Gen), produced from 2007 to 2013, is a full-size pickup truck renowned for its robust performance, towing capacity, and versatility. A key component of its reliability is its well-organized electrical system, with fuse boxes and relays playing crucial roles.

The fuse box in the Chevrolet Silverado 2nd Gen is typically located in two primary locations: the engine compartment and the interior, often under the dashboard on the driver’s side. The engine compartment fuse box controls high-power components like the engine, transmission, and anti-lock brakes, while the interior fuse box manages accessories such as the radio, power windows, and interior lights. Each fuse is designed to protect a specific circuit by disconnecting power in the event of an overload or short circuit.

Relays in the Silverado function as electrically controlled switches that manage high-current circuits for components like the fuel pump, starter motor, and cooling fans. These relays ensure that high-power systems can be controlled safely by low-power electrical circuits. Maintaining the fuses and relays is essential for preventing electrical malfunctions and ensuring the truck’s systems operate efficiently and 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.
