Locate the power distribution unit near the battery and check the cover legend to match each slot with its assigned circuit before removing any component.
The engine compartment assembly contains high-amperage links for starter, charging system, and cooling fans, while the interior unit handles lighting, radio, and accessory circuits. Each position is labeled with a number and rating, which must be matched exactly during replacement to avoid electrical faults.
Access inside the cabin is typically through a panel below the dashboard on the driver side. Remove the cover carefully to reveal a grid of small blade-type components arranged in rows. Use the printed chart on the panel to identify each circuit instead of guessing based on position.
In the engine area, the main distribution block is enclosed in a plastic housing with clips or tabs. Open it to find larger cartridge-style elements grouped near the main power feed. These protect systems that draw higher current and are placed closer to the battery for direct connection.
Always disconnect the negative terminal before handling any electrical parts, and inspect each piece for a broken metal strip inside. Replace only with the same amperage rating to maintain proper circuit protection.

Use the cover legend on the power distribution unit to identify each circuit position before removing any component and match amperage values exactly.
The engine compartment electrical center is positioned near the battery and contains high-current links for systems such as ignition, radiator fan, and charging circuit. These elements are arranged in a compact grid, with larger cartridge-style units placed closest to the main power feed.
Inside the cabin, a secondary panel is mounted beneath the dashboard on the driver side, housing low-amperage blade components responsible for interior lighting, radio, and accessory circuits.
Each slot within both locations is numbered and corresponds to a specific function. The numbering sequence follows a structured layout, allowing quick identification when paired with the printed chart on the cover panel.
Check the internal metal strip of each component after removal; a visible break indicates failure and requires replacement with an identical rating.
High-load circuits are grouped together in the engine area, while smaller circuits are separated in the interior section to prevent overload and simplify troubleshooting.
Always disconnect the negative battery terminal before accessing either electrical center to avoid short circuits or accidental contact with live terminals.
After installing a new component, ensure it sits firmly in place and reattach all covers securely to protect against moisture and debris intrusion.
Exact fuse box locations in engine bay and cabin with access steps
Open the engine compartment and locate the main electrical distribution unit next to the battery on the driver side, then release the plastic clips securing the cover to access the internal components.
This external unit is mounted close to the power source for direct current flow and contains larger cartridge-style elements. To reach it safely:
- Turn off ignition and remove the key
- Disconnect the negative battery terminal
- Press or lift the locking tabs on the cover
- Raise the lid to expose internal layout
Inside the cabin, the secondary electrical panel is positioned beneath the dashboard on the driver side, slightly to the left of the steering column. Remove the trim panel by pulling it outward to reveal a grid of blade-type components arranged in rows.
For interior access, follow these steps:
- Ensure all electrical systems are switched off
- Locate the removable panel below the dash
- Pull the cover straight out without twisting
- Use the included puller tool to remove components
After completing work in either location, reinstall all covers firmly to protect connections from dust and moisture, and reconnect the battery terminal before testing systems.
