Locate the interior fuse panel beneath the dashboard on the driver side and match each slot to its circuit using the label on the cover, ensuring correct identification before removing any fuse.
Check amperage ratings printed on each fuse, as installing a higher-rated component can overheat wiring and damage connected systems. Typical values range from 5A for control modules to 30A for power accessories.
Open the hood and find the power distribution box near the battery, which contains high-current fuses and relays for systems like cooling fans, ignition, and charging circuits.
Use a multimeter to verify continuity across fuse terminals, since visual inspection alone may miss small breaks that interrupt current flow under load.

Identify each fuse position using the printed chart inside the cover before removal, focusing on both the cabin panel under the dashboard and the engine bay distribution unit near the battery.
The interior fuse panel manages most low and medium load systems such as lighting, radio, and dashboard electronics. Each slot is numbered and paired with a specific amperage value, typically ranging from 5A to 30A.
Common interior fuse assignments include lighting circuits, turn signals, and accessory power outlets, all of which rely on correctly rated fuses to maintain stable operation.
The engine compartment fuse box contains high-current protection components for systems like cooling fans, ignition, and charging circuits, using larger fuses and relays.
Typical under-hood fuse ratings:
- 30A–40A for cooling fans
- 40A–50A for ignition and main relays
- 60A and above for primary power distribution
Inspect each fuse visually and test with a multimeter for continuity, as small internal breaks may not be visible but still interrupt electrical flow.
Ensure each fuse is firmly seated after inspection, since loose connections can cause intermittent electrical issues and unreliable system behavior.
Close both fuse boxes securely after completing checks to prevent moisture and debris from affecting the electrical system.
Passenger compartment fuse panel layout and slot identification
Locate the passenger compartment fuse panel beneath the driver side dashboard and use the cover chart to identify each slot, matching numbers with circuit labels before removing any fuse.
The panel is arranged in a grid pattern with clearly numbered positions. Each slot corresponds to a specific circuit, and the amperage value is printed on top of each fuse for quick reference.
Typical fuse assignments include:
- 5A–10A: instrument cluster, airbag system, control modules
- 15A: brake lights, turn signals, interior lighting
- 20A: wipers, washer system
- 25A–30A: power windows, HVAC blower motor
Use a flashlight to read slot numbers accurately, as the panel is positioned low and partially hidden, making misidentification possible without proper lighting.
Each fuse fits tightly into its slot, and removal should be done using a fuse puller or needle-nose pliers to avoid damaging surrounding components.
Check both the fuse number and its function on the cover chart to ensure the correct component is being inspected or replaced.
After completing checks, reinstall each fuse firmly and secure the panel cover to protect the electrical system from dust and accidental contact.
