Check the power distribution center cover first and match each slot with its labeled circuit before removing any component to avoid installing the wrong rating.
The engine compartment contains a primary electrical module positioned near the battery, handling high-current systems such as starter motor, cooling fan, and charging circuit. Each slot is marked with a number and amperage value, which must be followed precisely during replacement.
Inside the cabin, a secondary panel is located beneath the dashboard on the driver side, holding smaller blade-style elements responsible for lighting, radio, and accessory circuits. Use the printed legend on the cover to identify each position accurately instead of relying on visual placement alone.
Always inspect the internal metal strip of each component after removal. A broken strip indicates failure and requires replacement with the same amperage to maintain proper circuit protection.
Disconnect the negative battery terminal before handling any electrical parts and ensure each component is fully seated after installation to prevent intermittent power loss.

Align the cover legend with the power distribution center and verify each slot number before pulling any component to avoid selecting the wrong circuit.
The engine compartment electrical unit contains high-current protection elements arranged near the battery feed, with larger cartridge-style pieces handling systems such as starter motor, radiator fan, and alternator output.
Each position is labeled with a number and amperage rating, allowing accurate identification of circuits like ignition, headlights, and control modules when matched with the printed chart inside the cover.
- High-amperage slots are placed closest to the main power input
- Lighting circuits are grouped along one side
- Accessory systems are located in lower-rated positions
- Relays are positioned separately for quick access
Inside the cabin, a secondary panel beneath the dashboard contains smaller blade-style components arranged in rows, dedicated to interior electronics such as radio, instrument cluster, and power outlets.
To interpret the layout correctly, match each numbered slot with its function label and confirm amperage before replacement. A mismatch can lead to circuit overload or component failure.
After removal, inspect the internal metal strip; if it is broken, replace it with an identical rating and press it firmly into place to ensure proper contact.
Reinstall all covers securely after servicing to protect connections from dust and moisture, which can cause corrosion and unreliable electrical performance.

Open the hood and check the power distribution center near the battery on the passenger side, as this is the primary under-hood electrical hub for this model. Release the plastic cover by pressing the side clips, then lift it straight up. Inside, components are arranged in labeled rows, typically with higher amperage links placed closer to the battery feed. Use the lid’s underside map to match each slot with its circuit, such as cooling fan, ABS, or ignition.
Inside the cabin, locate the interior electrical panel behind the glove compartment or beneath the dashboard on the driver side. Access requires opening the glove compartment fully and gently pressing inward on both sides to drop it down, or removing a small trim cover under the steering column depending on trim level. Once exposed, identify slots by number and rating before removing any element. Follow these steps for safe access:
- Switch ignition off and remove the key
- Disconnect the negative battery terminal for safety
- Use a puller tool or needle-nose pliers for removal
- Match amperage exactly when installing a replacement
- Secure all covers firmly after inspection
