The Chrysler Newport (1979-1981) is offered primarily as a full-size sedan with a classic boxy design, featuring spacious interiors and rear-wheel drive. Known for its robust body style, the Newport emphasizes comfort and durability. It includes features like power steering, air conditioning, and optional luxury upgrades like power windows and seats.

The car’s electrical systems, including headlights, wipers, and the heating/AC system, are protected by the fuse box, typically located under the dashboard. The fuses ensure that electrical surges or short circuits do not damage the Newport’s essential features. If a fuse blows, it disconnects power to protect the system.

Relays in the Newport control high-current components such as the fuel pump and ignition system. These relays allow smaller electrical currents to manage larger systems, acting as electrical switches. A malfunctioning relay can disrupt essential functions like starting the engine or running the cooling fans.

Regular maintenance of the fuse box and relays is vital for keeping the Newport’s features running smoothly, ensuring longevity and reliability of its electrical components.

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.
