Learn about Chrysler LeBaron 1977-1981 fuse box and relay’s locations, functions, and maintenance tips for optimal vehicle electrical system.
The Chrysler LeBaron (1977-1981) offers various body styles, including a coupe, sedan, and station wagon. Known for its classic luxury and comfort, the LeBaron features plush interiors, power windows, and advanced-for-its-time air conditioning systems. These electrical features are supported by the fuse box and relays, which ensure proper functioning.
The fuse box, located under the dashboard, protects essential electrical components like the lights, radio, and power windows from electrical overloads. If a fuse blows, it disconnects the circuit, preventing potential damage to the system.
The relays control systems such as the horn, headlights, and power accessories. These act as switches, allowing low-current circuits to manage higher-current functions. A faulty relay can lead to malfunctions like inoperative headlights or horn issues, affecting overall driving safety.
Regular inspection of the fuses and relays is crucial to keep the LeBaron’s luxurious electrical features operating smoothly, ensuring that everything from power accessories to lighting functions properly.

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.
