The Chevrolet Cavalier (1995-2005) depends on its fuse box and relays to regulate its electrical system. The fuse box is located under the dashboard on the driver’s side, managing critical functions such as the headlights, turn signals, radio, and wipers. Each fuse in the box is designed to protect specific circuits by cutting off power when an overload or short circuit occurs, preventing potential damage to the electrical system.

The Cavalier also utilizes relays to control high-power functions, including the cooling fan, starter motor, and fuel pump. These relays act as switches, allowing a small current to control larger electrical loads. If a relay malfunctions, it can disrupt vital operations, such as preventing the engine from starting or causing the cooling fan to stop working.

Regular inspection and replacement of fuses and relays in the Chevrolet Cavalier ensure that the vehicle’s electrical systems continue to function properly, avoiding common issues like blown fuses or faulty relays that could lead to system failures.

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.
