Locate the main power distribution unit beneath the dashboard on the driver’s side for quick access to circuit protection elements. Identifying the exact slot assignments will prevent accidental overloads when replacing connectors or inspecting live circuits.
Reference the labeling chart inside the protective cover to match each miniature switch to its corresponding system, from headlights and cabin lighting to the HVAC control module. Cross-checking amperage ratings ensures that replacements maintain the integrity of sensitive electronics.
Check secondary modules under the hood near the battery and along the main wiring harness. Each compartment houses specific relays and safety cut-offs that control engine management components and auxiliary accessories, reducing the risk of shorts during maintenance.
Use a tactile approach when inspecting contacts, gently pressing connectors to confirm secure seating without forcing them. Documenting the position of removed elements avoids confusion during reassembly, especially for systems linked to infotainment and anti-lock braking functions.

Locate the main distribution board beneath the dashboard on the driver’s side to access circuits controlling headlights, power windows, and climate modules. Each slot carries a specific amperage rating–commonly 10A, 15A, 20A, or 30A–marked clearly on the cover. Use a tester or replacement link to identify any tripped circuits before attempting swaps.
Under the hood, the secondary electrical hub sits near the battery and manages the ignition, fuel pump, and cooling fan systems. Slots are numbered, often with an adjacent chart printed on the underside of the lid. Maintaining a log of any removed or replaced components prevents accidental mix-ups during repairs.
Slot Configuration and Identification
- Slot 1–Headlamp left
- Slot 2–Headlamp right
- Slot 3–Front wiper motor
- Slot 4–Horn and turn signals
- Slot 5–Auxiliary power outlet
For troubleshooting, always disconnect the negative terminal of the battery before handling links. Replacements must match the original amperage; exceeding limits risks wiring damage. A compact tester can verify continuity across terminals, ensuring circuits remain functional without trial-and-error removal.
Maintenance Tips
- Check connectors for corrosion monthly.
- Keep spare links of common ratings in the glove compartment.
- Mark any swapped positions with tape for reference.
- Inspect the hub cover for cracks that may allow moisture ingress.
Familiarity with both interior and engine compartment boards shortens diagnostic time. For older models, printed charts may fade, so photographing the layout provides a permanent reference before performing replacements or upgrades.
Locating the Electrical Distribution Center in a 2013 Altima
Check under the dashboard on the driver’s side, just to the left of the steering column. A rectangular cover secured with clips conceals the relay and protective circuits. Pulling this cover off reveals numbered slots corresponding to individual circuit protectors.
Under the hood, near the battery, a secondary access unit contains high-current safeguards. Lift the lid to inspect or replace modules; labels printed on the underside indicate amperage and connected systems.
Some protective components are grouped near the footwell on the passenger side. Look for a small, black enclosure tucked against the firewall; removing the latch allows access to multiple miniature circuits simultaneously.
Access Tips
Always switch the ignition off and disconnect the negative terminal before handling any protective modules. Use a flashlight to identify markings, as ambient light often makes the labeling difficult to read. Keep a reference chart or photo for quick identification.
Periodic inspection of these electrical safeguards helps spot wear or corrosion early. Gently press each connector to ensure a firm fit and replace any damaged components immediately to maintain safe operation of all systems.
