The Cadillac Eldorado, produced between 1997 and 2002, was a luxury coupe known for its elegant design, powerful performance, and advanced features. Its electrical system, including the fuse box and relay components, played a crucial role in its functionality and reliability.
The fuse box in the Cadillac Eldorado contained various fuses designed to protect specific electrical circuits throughout the vehicle. These circuits powered essential components such as the engine control module, lighting systems, climate control, entertainment features, and more. Fuses were crucial as they would interrupt the circuit in case of an electrical overload or short circuit, preventing damage to associated systems.
Relays in the Cadillac Eldorado acted as electrically operated switches that controlled high-current circuits. They enabled precise activation and deactivation of functions like the starter motor, fuel pump, air conditioning compressor, and power windows or seats. Efficient management of power distribution by relays contributed to the vehicle’s overall performance and reliability.
Routine inspection and maintenance of the fuse box and relays were essential to ensure the Cadillac Eldorado operated smoothly. This involved checking fuses for signs of wear or damage, ensuring relay connections were secure, and promptly addressing any electrical issues that arose. Proper care of these components helped maintain the vehicle’s electrical integrity, enhancing safety and driving pleasure in the Cadillac Eldorado 1997-2002.

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.
Cadillac Eldorado 1997-2002 fuse assignment
- Cigar lighter (power outlet) fuses in the Cadillac Eldorado are located in the Engine Compartment fuse box (see fuses “CIG LTR1” (Front and Rear Cigarette Lighters (Full Console Only)) and “CIG LTR2” (Right and Left Rear Cigarette Lighters)).
Year of production: 1997, 1998, 1999, 2000, 2001, 2002
Engine compartment
The fuse boxes are located on the driver’s side of the engine compartment, under the shroud cover.
- Lift the cover to gain access to the block.
- For access to the MaxiFuse/Relay Center remove the shroud cover.
Luggage compartment
The fuse block is located on the front wall of the trunk on the driver’s side. Loosen the four trunk trim fasteners and pull the trim away from the block to gain access.
