Locate the interior electrical distribution unit behind the passenger-side kick panel or beneath the dashboard, then match each numbered slot with the printed legend on the cover before removing any component.
The cabin section handles low to mid-current circuits such as radio, instrument cluster, HVAC controls, and power outlets. Each slot is labeled with a specific amperage rating, typically ranging from 5A to 20A, which must be followed exactly during replacement to avoid wiring damage or malfunction.
In the engine compartment, find the primary power distribution module near the battery; this unit contains high-current protection links and relays for systems like the starter motor, cooling fans, ABS, and charging system. The cover includes molded markings that correspond to each position, allowing quick identification without external references.
Check each element visually for a broken metal strip or discoloration, then confirm continuity using a multimeter if needed. Keep spare components with matching ratings and a small puller tool nearby to handle tight placements without damaging terminals.

Match each numbered slot with the legend printed on the cover and confirm amperage values before removal; interior distribution units group circuits by function for faster troubleshooting.
The cabin electrical block is arranged in rows with clear numbering. Typical assignments include:
- Row A: instrument cluster, steering controls, interior lighting
- Row B: audio system, climate interface, accessory outlets
- Row C: door locks, window motors, seat adjustment modules
Each slot carries a stamped rating such as 5A, 10A, 15A, or 20A. Lower values protect sensitive electronics, while higher ratings support motors and heating elements. Installing a higher-rated component risks overheating wiring harnesses.
The engine compartment power center handles high-load systems and relay switching. Common circuit assignments include:
- Cooling fan control with 40A protection
- ABS module supply with 30A rating
- Starter relay and ignition feed circuits
- Charging system link connected to alternator output
Relays share identical shapes, so use molded identifiers next to each socket to avoid swapping positions. Incorrect placement may disable critical systems such as ignition or cooling.
Check internal metal strips for breaks or dark marks. If visual inspection is unclear, test continuity with a multimeter across both terminals. Keep spare components and a plastic puller tool inside the cabin for quick access during electrical faults.
Cabin fuse panel location and slot mapping for dashboard systems
Open the passenger-side kick panel or remove the trim beneath the glove compartment to access the interior electrical distribution unit; this area holds most dashboard-related circuits.
The housing sits behind a snap-on plastic cover secured by clips. Once removed, a printed legend appears on the inner side, showing numbered positions aligned in rows. These numbers correspond directly to specific systems, allowing quick identification without tracing wires.
Upper row positions typically control low-current electronics such as instrument cluster, steering wheel switches, and interior illumination. These slots often use 5A or 7.5A components designed for sensitive modules.
Middle row assignments focus on cabin comfort and media systems, including radio unit, climate control interface, and auxiliary power outlets. Ratings here usually range from 10A to 20A depending on load demand.
Lower row slots handle higher-draw devices like power windows, door locks, and seat motors. These positions may use 20A or 30A components, requiring careful matching during replacement to prevent overheating or malfunction.
Use a flashlight to read stamped slot numbers and keep a plastic puller tool nearby for safe removal. Label frequently accessed circuits with a marker to reduce time spent searching during repeated electrical checks.
