Locate the main electrical distribution block under the hood near the battery and the secondary unit inside the cabin on the driver side to quickly identify circuit protection points.
Each slot is marked with a specific amperage value, usually ranging from 5A to 50A, depending on the load it supports. Higher ratings are assigned to systems like starter control, cooling fans, and ABS, while lower values protect lighting, radio, and accessory circuits.
Use the numbering printed on the cover to match each position with its assigned function. This allows fast troubleshooting when dealing with issues such as power window failure, non-working dashboard lights, or inactive outlets.
The engine compartment unit contains both protective elements and relays for switching high-load systems, while the interior block focuses on low-current circuits arranged in compact rows for easier access behind trim panels.

Inspect the under-hood power distribution unit first to identify high-current circuits linked to starting, charging, and cooling systems, as these positions handle the largest electrical loads.
This engine compartment assembly contains cartridge-style and blade-type elements with ratings typically between 20A and 50A, arranged in a grid with clear numbering for quick reference.
Common circuit assignments include:
- 30A slot for radiator fan operation
- 40A slot for ABS control module
- 50A slot for ignition power feed
- 20A slot for fuel pump system
The cabin-mounted electrical block is positioned behind the driver-side trim and manages lower-demand circuits such as dashboard lighting, radio unit, and power accessories.

These interior positions are grouped in tight rows and typically use lower ratings ranging from 5A to 25A, allowing precise protection for smaller components without affecting larger systems.
Typical interior circuit roles:
- 10A for instrument cluster and warning lights
- 15A for audio system and cigarette lighter
- 20A for power windows and door locks
Relays are mainly located in the engine bay unit, where they control switching for systems like starter engagement and cooling fan activation, reducing load on cabin switches and wiring.

Under hood fuse panel location and high current circuit assignments

Open the hood and locate the main power distribution unit near the battery, usually secured with a plastic cover that snaps into place and protects high-load connections from dirt and moisture.
This compartment contains large-capacity protective elements designed for circuits drawing significant current, with ratings commonly ranging from 30A up to 60A, depending on the system served.
Primary high-current assignments include:
Cooling fan motors, anti-lock braking module, ignition supply line, and main feed to the interior electrical network, all grouped for direct battery access and minimal voltage drop.
Typical amperage roles: 30A for fan operation, 40A for ABS pump, 50A for ignition distribution, and 60A for overall system feed into cabin wiring.
Relays are integrated within this under-hood unit, controlling switching for starter engagement, fuel delivery activation, and fan cycling, reducing stress on dashboard switches.
Each position is labeled with a number that corresponds to a legend inside the cover, allowing quick identification of circuits without tracing wires manually across the engine compartment.
Always replace components with identical ratings and types to prevent overheating, wiring damage, or failure of connected systems.
