Check both the engine bay and cabin power distribution units first, as this vehicle uses two separate blocks to manage electrical loads. Use a multimeter to verify voltage at each slot before removing any protective link, and always match the amperage marking.
The under hood power distribution center handles high current systems such as cooling fans, ABS, and ignition circuits, while the cabin unit supports lighting, radio, and accessory controls. A printed circuit layout is typically located inside each cover, showing slot numbers and assigned components.
Amperage values range from 5A for control modules up to 40A or more for heavy load systems. If a circuit stops working, inspect not only the link but also relay positions and nearby wiring for signs of heat or corrosion.
Access covers are secured with clips or latches, and both units are designed for quick inspection without tools. Keep spare links in common ratings such as 10A, 15A, and 20A, along with a basic tester, to restore power during roadside checks.

Match each slot in the power distribution units with its assigned circuit using the layout printed inside the covers, then verify current flow with a multimeter before removing any protective link. Focus first on systems like fuel pump, ignition, and lighting, as they reveal faults quickly.
The engine bay unit contains high current circuits such as cooling fans, ABS module, and starter relay, while the cabin block handles low to mid range loads like audio system, power windows, and dashboard controls. Typical ratings include 10A for electronics, 20A for accessory lines, and 30A or higher for motors. Use wire color and connector position to confirm each circuit if markings are unclear.
Check voltage on both sides of each slot to determine whether the issue lies in the protective link or downstream wiring. If power is present at the input but not at the output, replace the link with the same amperage rating and inspect terminals for looseness or heat damage.
Exact locations of fuse boxes in engine bay and cabin area
Open the hood and locate the main power distribution center on the driver side near the battery, as this unit handles high current circuits and relays. It is enclosed in a black plastic housing with a snap-on lid.
Release the side clips and lift the cover to access internal slots. Inside, you will find a printed layout showing circuit assignments for systems such as cooling fans, ignition, and ABS.
Inside the vehicle, check the passenger side footwell area where the secondary electrical block is mounted behind a trim panel. It sits below the dashboard, close to the kick panel, and is accessible without removing major components.
Follow these steps to reach the cabin unit:
- Move the passenger seat back for better access
- Remove the lower trim panel using gentle pressure on clips
- Locate the mounted block fixed to the inner dash frame
- Use a flashlight to read slot markings and labels
Both locations are designed for quick inspection. Keep the ignition off while accessing them, and ensure covers are securely reattached after checking to prevent moisture or debris from entering.
