Finding and inspecting blown fuses on a 2017–2026 Cadillac XT5 involves checking three primary power distribution locations: the Engine Compartment Fuse Block, the Instrument Panel Fuse Block, and the Rear Cargo Compartment Fuse Block.
Fuse Box Locations
-
Engine Compartment Fuse Box: Located on the driver's side of the engine bay, situated directly behind the 12V battery and brake fluid reservoir. Release the plastic locking latches on the cover lid to pull it up and access the main relays and high-amp fuses.
-
Instrument Panel (Passenger Compartment) Fuse Box: Located in the cabin on the lower passenger side of the center console (behind the small removable access door panel in the passenger footwell area).
-
Rear Cargo Compartment Fuse Box: Located under the rear load floor storage compartment, situated on the driver's side trim panel in the luggage area near the spare tire/storage tray.

How to Check & Replace a Blown Fuse
-
Turn off the ignition switch, remove the key fob, turn off all exterior and interior lights, and set the electronic parking brake (EPB).
-
Access the targeted fuse panel (Engine Bay, Passenger Footwell Console, or Rear Cargo Storage area) and detach the protective cover.
-
Use the plastic fuse puller clip clamped inside the engine compartment fuse box lid to extract the target fuse.
-
Inspect the translucent fuse body. If the internal metallic bridge wire is melted, cracked, or broken, replace it with a spare fuse of the exact same amperage rating.
