Locate the cabin and engine bay electrical distribution units first to identify the exact circuit linked to a malfunction such as lighting, wipers, or infotainment. The interior unit is usually positioned behind a dashboard panel, while the engine compartment unit sits near the battery.
Each slot is marked with a number and amperage rating, typically ranging from 5A to 40A. Lower values protect control modules and cabin electronics, while higher ratings support components like cooling fans, ABS, and ignition systems.
Use the cover label or service manual chart to match slot numbers with their assigned functions. For instance, a 10A position may control interior lighting, while a 25A or 30A position is often linked to power windows or HVAC systems.
Keep spare blade fuses and a puller tool nearby for quick diagnostics. A simple visual check of the internal metal strip helps detect a break without using test equipment.

Check the passenger side dashboard compartment first, where the interior electrical block is hidden behind a removable trim panel. Open the glovebox or side cover and release the clips to expose the unit.
This cabin-mounted module contains low-current protection elements for lighting, infotainment, climate control, and dashboard electronics. Access is limited, so use a flashlight to read slot numbers and amperage markings clearly.
Cabin access details
The unit is positioned behind a plastic cover secured by clips, requiring no tools for removal. It holds mini blade fuses rated between 5A and 25A, each assigned to specific interior systems.
Open the hood and locate the main power distribution unit near the battery, usually on the left side of the engine bay. Press the locking tabs on the cover and lift it upward to gain access.
This under-hood unit handles higher load circuits such as cooling fans, ABS, and ignition. The underside of the cover includes a printed layout showing slot numbering and circuit roles, which helps identify the correct component quickly.

Use the printed layout on the cover to match each slot number with its amperage and circuit role, ensuring accurate identification of the electrical path tied to a malfunction.
Cabin-side slots usually carry low-current protection, ranging from 5A to 25A. For example, position F2 (10A) supports interior lighting, F6 (15A) is assigned to the audio system, and F11 (20A) powers accessory outlets.
Engine compartment slots handle higher loads. Positions like F14 (30A) operate the cooling fan, F20 (40A) is linked to ABS, and F23 (30A) supports ignition-related circuits.
Each slot number is molded into the housing next to its position, while amperage values are indicated by color coding such as red for 10A, blue for 15A, and yellow for 20A, reducing selection mistakes.
Relays are integrated within the same housing and control switching for systems like fuel pump, starter motor, and air conditioning compressor. These components are larger and often labeled separately.
Confirm both slot index and amperage before replacement, as incorrect ratings may cause overheating or repeated failures in the electrical system.
How to check blown fuses and replace them correctly in Renault Scenic 2
Remove the suspected fuse using a puller and inspect the metal strip; a visible break or burn mark confirms failure and requires replacement.
Identify the correct slot by matching the affected system, such as wipers or radio, with its assigned number in the layout chart located on the cover or in service documentation.
Use a multimeter for confirmation by setting it to continuity mode and touching both terminals; no signal indicates an open circuit inside the fuse.
Turn off the ignition and disconnect the battery if working with high-current circuits in the engine bay. This prevents accidental short circuits and protects electronic modules.
- Locate the correct amperage rating printed on the fuse
- Match the color code exactly
- Insert the new fuse firmly into the same slot
- Ensure it sits flush with surrounding components
Installing a higher-rated fuse can cause wiring damage, while a lower-rated one may blow under normal load conditions, leading to repeated issues.
After replacement, test the affected system immediately to verify proper operation and confirm that no additional faults are present.
Keep spare fuses of common ratings like 10A, 15A, and 20A in the glovebox for quick fixes during unexpected electrical failures.
