The Cadillac SRX, produced from 2004 to 2009, is a midsize luxury crossover SUV known for its spacious interior, comfortable ride, and advanced features. Its electrical system, including the fuse box and relay components, is integral to its functionality and performance.
The fuse box in the Cadillac SRX houses a series of fuses that protect various electrical circuits throughout the vehicle. These circuits power critical components such as the engine control module, lighting systems, entertainment features, climate control, and more. Fuses are designed to break the circuit in the event of an electrical overload or short circuit, preventing damage to the associated systems.
Relays in the Cadillac SRX serve as electrically operated switches that control high-current circuits. They play a crucial role in activating functions such as the starter motor, fuel pump, air conditioning compressor, and power windows or seats. By managing power distribution effectively, relays ensure that each component receives the necessary voltage for optimal operation.
Regular inspection and maintenance of the fuse box and relays are essential to ensure the Cadillac SRX operates reliably. This includes checking fuses for signs of wear or damage, ensuring relay connections are secure, and addressing any electrical issues promptly. Proper care of these components helps maintain the vehicle’s electrical integrity, enhancing safety and driving comfort in the Cadillac SRX 2004-2009.

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 SRX 2004-2009 fuse assignment
- Cigar lighter / power outlet fuses in the Cadillac SRX are located in the Engine compartment fuse box (and in the Driver’s Side Rear Underseat Fuse Box (since 2007)). 2004-2006 – see fuses “OUTLET” (Center Console Accessory Power Outlet) and “I/P OUTLET” (Instrument Panel Accessory Power Outlet). 2007-2009 – see fuses “CIG” (Instrument Panel Accessory Power Outlet), “AUX OUTLET” (Center Console Accessory Power Outlet), and in the Rear Underseat Fuse Box (Driver’s Side) – see fuse “APO” or “AUX PWR OUTLET” (Rear Auxiliary Power Outlet).
