Learn about Cadillac CTS-V 2009-2014 fuse box and relay’s locations, functions, and maintenance tips for optimal vehicle electrical system.
The Cadillac CTS-V (2009-2014) is a high-performance version of the CTS sedan, known for its aggressive styling and powerful supercharged V8 engine. Available as a sedan, coupe, and wagon, the CTS-V appeals to drivers seeking luxury and thrilling performance. Its sporty body style is complemented by a refined interior and advanced technology, making it a standout in the luxury sports car segment.
To manage the advanced electronics and high-power components, the CTS-V’s electrical system relies on strategically placed fuse boxes and relays. The primary fuse box is located under the hood on the driver’s side, providing easy access to fuses that control key systems like lighting, engine management, and climate control. Another fuse box is often located in the trunk or cabin for interior features. Relays, responsible for high-demand components like the fuel pump and ignition, are housed near these fuse boxes to ensure efficient power distribution.

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.
