Check the power distribution layout first using the label inside the cover before replacing any blown link, as each slot is tied to a specific circuit with a fixed amperage rating.
Inside this full-size sedan, electrical protection is divided between multiple panels, including one under the hood and another inside the cabin. Each section contains numbered positions that correspond to systems like lighting, audio, climate control, and control modules. Matching the correct slot number prevents installing the wrong rated component.
Use a puller tool stored in the panel cover to remove a damaged element and inspect the metal strip. A broken or burned strip indicates failure. Replace it only with the same amperage value, typically ranging from 5A to 30A for interior circuits and higher ratings in the engine compartment for high-load components.
Pay attention to circuit labels printed on the cover or in the service manual, as they identify functions such as fuel pump relay, ignition system, or power windows. Incorrect replacement can lead to wiring damage or malfunction of multiple systems.
Access panels by removing trim covers without force. Interior access usually requires opening a side panel near the dashboard, while the under-hood unit is secured with clips. Keep spare links in the vehicle to handle sudden electrical interruptions without delay.

Match each slot number with its assigned circuit before any replacement, using the printed layout inside the cover to avoid disconnecting the wrong system.
The under-hood power distribution center contains high-amperage links for components such as cooling fans, ABS module, and starter relay. These positions typically range from 30A to 60A and are arranged in rows with clear numbering. Interior electronics like radio, instrument cluster, and seat controls are protected by lower-rated elements located inside the cabin panel, usually between 5A and 25A.
Each cavity is labeled with a function code that corresponds to a specific system. For example, IGN refers to ignition circuits, HVAC to climate control, and BCM to body control module. Reading these abbreviations correctly prevents misidentification during troubleshooting and reduces the risk of disabling multiple features at once.
Use a test light or multimeter to confirm power flow across the metal strip before removing it. A failed link shows no continuity. Replace only with identical amperage and size, as installing a higher rating can lead to wiring overheating and component damage.
Exact location of fuse panels in cabin trunk and engine compartment

Locate the interior panel first by opening the driver-side door and removing the side trim cover on the dashboard edge; it snaps off with light pressure and reveals the primary low-current protection area.
This cabin section contains slots assigned to control modules, lighting circuits, and infotainment. The cover usually includes a printed map with position numbers aligned in vertical rows, making identification faster during checks.
Access the engine compartment unit by lifting the hood and looking near the battery on the driver side. A rectangular plastic housing with locking tabs protects high-current links and relays. Press the tabs inward and lift the lid to expose the internal layout.
Under-hood distribution is arranged in grouped sections:
- Front row for cooling and fan control
- Center section for ignition and starter circuits
- Rear section for ABS and powertrain modules
Open the trunk to find the rear panel, positioned behind a side liner, typically on the left side. Pull back the carpeted cover to reveal another protected area handling rear electronics.
This rear compartment supports systems such as air suspension, audio amplifier, and fuel-related components. Labels are printed on the inside panel cover, showing slot numbers and amperage values.
Follow this sequence during inspection:

- Disconnect ignition
- Open the correct panel based on affected system
- Match slot number with printed layout
- Remove and inspect the metal strip
Keep a small puller tool and spare links in the glove compartment, as access to all three panel locations may be required during a single electrical fault check.
