Find the fuse box and relay locations for the 2010-2014 Cadillac CTS Wagon with clear diagrams. Essential guide for dependable operation of key electrical components.
The Cadillac CTS Wagon (2010-2014) offers a unique blend of luxury, performance, and versatility, setting it apart in the luxury wagon segment. With its sleek body style, spacious cargo area, and high-quality interior, the CTS Wagon provides both comfort and practicality. Available with various trim levels, including a powerful V6 engine, it caters to those who value Cadillac’s signature refinement with added utility.
The CTS Wagon’s advanced features rely on a robust electrical system, supported by its fuse boxes and relays. The primary fuse box is located under the hood in the engine bay, while a secondary fuse box can be found inside the cabin, typically on the passenger side beneath the dashboard. Relays, which control high-power devices such as the fuel pump and cooling fan, are housed near these fuse boxes. Regularly inspecting and maintaining these components helps ensure the vehicle’s electronic systems continue to perform reliably.

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.
