Check the driver-side dash panel and the engine compartment power distribution unit first, then match each numbered slot with the printed legend to identify the correct circuit before removing any insert.
This compact sedan uses two main electrical centers: one inside the cabin for low-current systems and another under the hood for high-load components. Each position is assigned to functions such as lighting, ignition, fuel delivery, and accessory systems. Amperage ratings are stamped on each insert, typically ranging from 5A to 40A depending on circuit demand.
Common electrical issues include non-working headlights, radio failure, or power window problems, often linked to a single blown protective link rather than a faulty component. Matching slot numbers with their assigned circuits helps isolate the issue quickly.
Inspect each insert for a broken metal strip, heat damage, or loose seating in the panel. Replace only with identical ratings and ensure a firm fit to maintain stable current flow across all connected systems.

Check the cabin-mounted electrical block first, typically positioned beneath the dashboard on the driver side, then match each slot number with the printed legend to identify circuit roles before removing any component.
The main distribution unit inside the cabin uses numbered slots linked to specific systems such as lighting, ignition, climate control, and audio. Standard ratings include 10A for lighting circuits, 15A for accessory power outlets, and 20A for blower motor supply. A second power center under the hood handles higher loads like radiator fans and ABS modules. Use the cover label or service manual chart to confirm assignments, as slot numbering may differ between trim levels. Always compare amperage markings stamped on each blade insert with the listed value; mismatches can lead to overheating or system failure. Disconnect the battery ground before inspecting terminals, and use a puller tool to avoid damaging contacts.
Interior fuse panel layout with slot numbers and electrical functions
Locate the cabin-mounted power distribution unit under the dash on the driver side, then align each numbered position with the legend printed on the cover before removing any blade insert.
The layout typically arranges slots in rows, with positions 1–5 assigned to lighting circuits such as tail lamps and instrument cluster illumination, usually rated at 10A. Slots 6–10 often handle accessories like radio, cigarette lighter, and power outlets, commonly marked at 15A. Positions 11–15 are linked to systems such as wipers, turn signals, and hazard lights, with ratings ranging from 10A to 20A. Each cavity number corresponds to a single protected line, so verify both the number and amperage stamped on the component before replacement. Incorrect ratings may cause wiring damage or intermittent faults. Use a test light or multimeter to confirm power at the terminals, and inspect contact clips for corrosion or looseness to maintain stable current flow.
