Check the vehicle’s electrical panel under the dashboard first, then verify the secondary unit in the engine bay before replacing any blown component. Use a test light or multimeter to confirm power flow rather than relying on visual inspection alone.
The cabin-mounted panel typically sits near the driver’s left knee, secured by a plastic cover. Inside, each slot corresponds to a specific circuit such as headlights, fuel pump, or radio. Match the amperage rating exactly when installing a new link, as using a higher value can damage wiring and connected devices.
Under the hood, the second distribution unit handles higher-load systems including cooling fans and ignition circuits. Corrosion or loose contacts in this area can interrupt current flow, so inspect terminals closely and clean them if needed. Keep a printed layout or labeled reference nearby to avoid confusion during diagnostics and repairs.

Locate the interior power distribution panel near the driver’s lower dash and verify each slot using a printed layout before removing any component. Always disconnect the battery negative terminal to prevent accidental short circuits during inspection.
The cabin panel contains low to medium load circuits such as interior lighting, radio memory, turn signals, and instrument cluster. Each position is marked with a number and paired with a specific amperage rating, typically ranging from 7.5A to 20A. Never install a higher-rated replacement, as wiring insulation can overheat and fail.
In the engine compartment, the secondary relay and protection unit supports high-current systems like radiator fans, ignition, and main power supply. These slots often use higher ratings such as 30A or 40A. Check for heat damage or discoloration around terminals, which indicates excessive load or poor contact.
Interior Panel Slot Functions and Ratings
Positions inside the cabin unit are assigned to specific systems: indicators, brake lights, wipers, and accessory circuits. Use a multimeter to test continuity across each metal strip instead of relying on visual checks, as small breaks can be hard to see. Labeling inside the cover panel usually provides a quick reference for each circuit.
Some slots share power distribution across multiple devices, so a failure may disable several functions at once. For example, one 15A slot may control both dashboard lighting and tail lamps. Trace the circuit using wiring color codes if multiple systems stop working simultaneously.

The under-hood unit includes primary links connected directly to the battery. These protect major electrical paths and are bolted rather than clipped in. Inspect mounting points for corrosion, and tighten connections if any looseness is detected.
When replacing any burned element in this section, use parts with identical size and rating. After installation, restore battery connection and test each related system individually to confirm stable operation without voltage drops or intermittent faults.
Where the fuse boxes are located and how to open them safely
Disconnect the negative battery terminal before accessing any electrical panel to avoid short circuits or accidental contact with live circuits.
The interior panel is positioned beneath the dashboard on the driver’s side, close to the left knee area. It is covered by a plastic lid that snaps into place and can be removed without tools.
- Look under the steering column
- Find a rectangular plastic cover
- Pull gently from the edge to release clips
Use steady pressure when removing the cover to prevent breaking retaining tabs. If resistance is high, check for hidden screws or secondary clips along the edges.
Engine Compartment Power Unit Location
The second protection panel is located in the engine bay, usually near the battery or along the inner fender. It is enclosed in a sealed plastic case designed to protect internal components from moisture and dirt.
- Open the hood and secure it properly
- Locate the rectangular housing near the battery
- Release the locking tabs or clips on the lid
- Lift the cover straight up without twisting
Check for dirt or debris around the seal before opening to prevent contamination inside the unit. Clean the surface with a dry cloth if needed.
Safe Access and Handling Tips
Avoid using metal tools when opening covers or handling internal components. Plastic trim tools are safer and reduce the risk of accidental contact with conductive parts.
- Keep hands dry during the process
- Do not force stuck covers
- Inspect clips and hinges for damage
- Store removed covers in a clean place
After inspection or replacement, press the covers firmly until all clips lock into place, ensuring proper sealing and protection from dust and moisture.
