Check the interior electrical panel on the driver-side dashboard first, as it controls most cabin systems such as lighting, radio, and accessory circuits. Remove the cover and use the printed layout to identify each slot and its assigned function.
The engine compartment distribution unit near the battery contains high-load protection links for ignition, cooling fan, and charging system. Use a multimeter or test light to confirm continuity instead of relying only on visual inspection.
Each component is labeled with an amperage rating, typically ranging from 10A to 50A depending on circuit demand. Always replace with the same value to avoid wiring damage or repeated failure.
If a circuit stops working again after replacement, inspect wiring, relays, and connectors for short circuits, corrosion, or loose contacts. Repeated issues usually point to a fault outside the distribution unit.

Check the legend on the cover first to match each slot with its assigned circuit before pulling any element, as this prevents disconnecting the wrong system such as ABS or fuel pump control.
The under-hood power distribution center groups high-amperage links for starter relay, cooling fan, and charging system. Inside the cabin, the smaller block handles lighting, radio memory, wipers, and HVAC controls. Each position is marked with a number that corresponds to a printed key, allowing quick identification without guessing.
Typical assignments include: ignition feed (10–20A), stop lamps (15A), turn signals (15A), power windows (20–30A), and instrument cluster supply (10A). Matching amperage is critical; installing a higher rating risks wiring damage, while a lower rating may cause repeated failure under normal load.
Use a puller tool or needle-nose pliers to remove a link and inspect the metal strip inside. If it is broken or darkened, replace it with the same rating. After replacement, test the related system immediately to confirm the issue is resolved and no secondary fault remains.
For clarity, organize checks in sequence: locate the correct slot using the layout map, confirm amperage marking, inspect condition, replace if needed, then verify operation. This structured approach reduces time spent tracing electrical issues across multiple circuits.
Interior fuse panel location and detailed circuit assignment list
Access the cabin-mounted block by opening the driver-side door and removing the cover at the end of the dashboard, facing the door hinge area for direct reach.
This interior unit manages low to medium current circuits tied to daily driving functions. The cover usually includes a printed index with numbered positions aligned to rows, allowing quick identification without disassembly of surrounding trim.
Common circuit assignments
- Position 1–3: instrument cluster feed and warning indicators 10A
- Position 4–6: radio memory and interior audio system 15A
- Position 7–9: turn signals and hazard lights 15A
- Position 10–12: windshield wipers and washer pump 20A
- Position 13–15: interior lighting and dome lamps 10A
Each slot uses color-coded links: red for 10A, blue for 15A, yellow for 20A. Match both color and printed value before installing a replacement to avoid overload or intermittent shutdown of connected components.
Inspection and replacement steps
- Turn ignition off and remove key
- Locate the numbered slot using the cover legend
- Pull the element with a plastic tool
- Check the metal strip for breaks or burn marks
- Install a new unit with identical rating
If multiple systems fail at once, inspect shared feeds such as accessory delay relay or ignition supply lines, as several cabin circuits may depend on a single source inside this block.
After replacement, test all related functions including lighting, wipers, and audio memory to confirm stable operation without recurring failure under load.
