Locate the interior electrical block beneath the dashboard on the driver side, directly behind a snap-on plastic cover; remove it carefully by pulling from the lower edge to reveal the full layout.
Use the label printed inside the cover to match each slot with its circuit, including lighting, ignition feed, and accessory power lines; incorrect placement leads to repeated electrical faults and unnecessary part replacement.
The engine compartment contains a secondary distribution unit near the battery, housing high-current links for starter motor, cooling fan, and charging system; inspect both interior and under-hood sections when diagnosing power loss.
Check amperage values stamped on each blade element before replacing; common ratings include 10A for interior electronics, 15A for control modules, and 20A or higher for motors and relays, ensuring proper load handling.

Check the interior power distribution unit under the driver side dash and align each slot with the printed index on the cover before pulling any component; this avoids mixing circuits tied to ignition, lighting, and accessories.
The cabin unit contains mini blade links arranged in rows, where upper positions usually handle higher load systems like blower motor and power windows, while lower positions feed low-current electronics such as radio memory and interior lamps.
Under the hood, a separate module near the battery includes larger cartridge-style links and relays controlling starter engagement, cooling fans, and fuel pump operation; inspect these when the engine fails to crank or overheats.
Typical slot functions inside the cabin include turn signal control, brake light supply, instrument cluster feed, and accessory socket power; matching amperage values–commonly 10A, 15A, and 20A–prevents overheating and wiring damage.
Relays within the engine compartment are square units that click when activated; swap with identical units of the same type to confirm faults in systems like horn, air conditioning clutch, or fuel delivery.
After inspection or replacement, push each element fully into its slot until seated flush; partial contact leads to intermittent voltage drops that can mimic sensor or module failure.
Exact Interior Fuse Box Location and Access Steps
Open the driver side lower dashboard cover located just left of the steering column; pull from the bottom edge to release the clips and expose the interior electrical distribution panel without tools.
Position your head below the steering wheel to clearly see the slot layout and printed index on the cover, then use a plastic puller to remove components one at a time; keep ignition off during access and avoid forcing tight elements to prevent terminal damage.
