Open the glove compartment and locate the main electrical chart to identify the correct circuit before removing any protective link. In this coupe, the primary distribution unit is mounted behind the glovebox, requiring you to release the retaining straps and lower the compartment fully. This gives direct access to rows of numbered slots linked to specific vehicle systems.
Each protective element is marked with a color and amperage value, typically ranging from 5A to 30A. Matching the exact rating is required to maintain circuit protection and prevent wiring damage. Use a puller tool stored inside the compartment to remove components without damaging surrounding connectors.
Additional electrical modules are positioned in the engine bay and rear compartment, handling higher load circuits such as cooling systems, lighting, and power accessories. Reference charts map each slot to its function, allowing accurate fault tracing when dealing with issues like non-working lights or intermittent electronic failures.

Use the reference chart behind the glove compartment to match each slot number with its circuit before removing any protective link. The layout is arranged in horizontal rows, with numbering that aligns directly with system functions such as lighting, audio, and control modules. Keep the chart visible while working to avoid pulling the wrong component.
Follow these steps to identify and verify a faulty element:
- Locate the numbered slot linked to the malfunctioning system
- Remove the component using the plastic puller tool
- Inspect the internal metal strip for breaks or burn marks
- Test continuity using a multimeter for confirmation
- Install a replacement with the same amperage rating
Color coding helps speed up identification and reduces errors during replacement:
- Brown indicates 7.5A circuits such as interior electronics
- Red corresponds to 10A lines like lighting controls
- Blue marks 15A positions often used for accessory systems
- Yellow shows 20A connections for higher load components
- Green represents 30A circuits including motors and power systems
Exact Fuse Box Locations in Glove Compartment Engine Bay and Trunk
Lower the glove compartment fully to access the primary electrical distribution area. Release the side dampers and press inward on both walls to drop it down. Behind it sits a large block with rows of protective links and relays, clearly numbered and aligned with a printed reference chart.
This interior location handles most low to medium load circuits such as audio system, climate control, interior lighting, and control modules. Keep the compartment supported while working to avoid stress on hinges.
Open the hood and inspect the right rear section near the windshield base. A sealed housing is mounted close to the cabin filter area, secured with clips or screws. This unit contains higher load circuits tied to engine management, cooling fans, and ignition components.
Remove the cover carefully and check for moisture or corrosion before touching any connectors. Always disconnect the battery when working in this area to prevent short circuits.
Lift the trunk floor and check the battery area on the right side. A secondary distribution unit is positioned near the battery, hidden behind trim panels. This section supports rear lighting, central locking, and power accessories.
Pull back the lining to reveal the housing. The layout here may include both standard blade-type elements and larger strip-style links for higher current flow.
Accessing all three locations allows full inspection of the vehicle’s electrical system. Checking each area in sequence helps isolate faults tied to specific sections without removing unnecessary components.
