The Cadillac Seville 1995, particularly the STS model, represented a significant redesign aimed at enhancing luxury and performance. This iteration of the Seville included an advanced electrical system incorporating a fuse box and relay setup that played pivotal roles in maintaining the vehicle’s operations.
The fuse box in the Cadillac Seville 1995 housed various fuses, each designed to protect specific electrical circuits throughout the vehicle. These circuits powered critical components such as the engine control module, lighting systems, climate control, infotainment features, and more. Fuses were essential for preventing electrical overload or short circuits, thus safeguarding the integrity of associated systems.
Relays in the Cadillac Seville 1995 served as electrically controlled switches managing high-current circuits. They facilitated the precise activation and deactivation of functions like the starter motor, fuel pump, air conditioning compressor, and power windows or seats. Relays played a crucial role in efficient power distribution, ensuring optimal performance of the vehicle’s systems.
Regular inspection and maintenance of the fuse box and relays were imperative to ensure the Cadillac Seville 1995 operated smoothly. This included 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 was essential for maintaining the vehicle’s electrical integrity, contributing to safety and driving satisfaction in the Cadillac Seville 1995.

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 Seville 1995 fuse assignment
- Cigar lighter / power outlet fuses in the Cadillac Seville are the fuse №. 23 in the Engine compartment fuse box and fuses №. 58 and 65 in the Rear Underseat fuse box.
