Locate the fuse box and relay positions in the Cadillac XT6 2020-2024 with detailed diagrams. Essential guide for maintaining electrical system reliability.
The Cadillac XT6 (2020-2024) is a midsize luxury SUV, designed with a focus on spaciousness and elegance. Available in several trims, it offers a three-row seating configuration, making it a perfect choice for families and those needing extra passenger capacity. The XT6’s exterior features Cadillac’s distinct styling with a bold grille, sleek LED headlights, and refined body lines. Inside, the cabin boasts high-quality materials, advanced infotainment, and safety technologies, ensuring comfort and convenience.
To support its advanced electrical features, the XT6 relies on a network of fuse boxes and relays. The primary fuse box is located in the engine compartment, while another is situated inside the cabin, typically near the passenger side. These fuse boxes protect various electrical circuits, while the relays, positioned nearby, handle high-power components such as the cooling fans and ignition system. Regular maintenance of these components is essential to keep all electrical systems functioning smoothly.

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.

Location of Fuse Boxes
Engine Compartment Fuse Block:
The underhood fuse block is in the engine compartment, on the driver side of the vehicle. To remove the fuse block cover, press the clips on the cover and lift it straight up.
Do not pull the engine compartment fuse block lever, since it is intended only for service purposes. If pulled, vehicle malfunction may occur.
Instrument Panel Fuse Block:
The instrument panel fuse block is in the center console between the driver and passenger seats. To access the fuses, open the fuse panel door, or remove the panel from the passenger side by pulling it out, or see your dealer.
Rear Compartment Fuse Block:
The rear compartment fuse block is in the cargo area, on the driver side of the vehicle behind the lower trim panel. To access the fuses in the Rear Electrical Center, remove the center cargo bin, then small side bin. The label for this fuse block is in the spare tire area, on the foam under the cargo floor.
