The Chevrolet HHR (2005-2006) is a retro-styled compact SUV known for its versatility and practicality. Its electrical system, which controls everything from essential engine functions to comfort features, relies heavily on the fuse box and relay systems to operate safely and efficiently.

The fuse box in the Chevrolet HHR is located in two primary areas: the engine compartment and inside the cabin, under the front passenger seat. The engine compartment fuse box protects high-power components such as the engine control system, cooling fans, and headlights. Meanwhile, the interior fuse box manages lower-power circuits like the radio, power windows, and interior lights. Each fuse serves to protect these circuits by breaking the connection in the event of an overload or short circuit.

Relays in the HHR function as switches for high-current systems, such as the starter motor, fuel pump, and air conditioning system. These relays allow the car’s low-current systems to control high-current operations efficiently and safely. Maintaining the health of both the fuses and relays is critical to ensure the proper functioning of the vehicle’s electrical systems and to prevent potential issues down the line.

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.
