Renault Duster Fuse Box: Location & Guide
TL;DR
Duster fuses live in two spots, an engine-bay box by the battery and a dash-end box on the driver side, and the lid diagram (not a generic online chart) is the only reliable source for exact positions and amperages.
Where the Renault Duster fuse boxes are located
The Duster was never officially sold in North America, so owners searching for this car are almost always driving the Brazil-built or broader Latin American version, which this guide treats as the reference vehicle. Renault kept the same basic two-box fuse layout across both generations sold in the region.
| Generation / years | Fuse box | Location | How to access |
|---|---|---|---|
| 1st gen (Brazil, approx. 2011-2019) | Engine compartment box | Next to the battery, driver side of the engine bay | Unclip or unscrew the plastic cover, which lifts straight up or hinges forward |
| 1st gen (Brazil, approx. 2011-2019) | Passenger compartment box | End of the dashboard on the driver side, near the door | Pry off the small trim cover with a flat tool or your fingertips, it unclips outward |
| 2nd gen (2020-present) | Engine compartment box | Next to the battery, driver side of the engine bay | Release the cover clips, the lid folds back on a hinge |
| 2nd gen (2020-present) | Passenger compartment box | End of the dashboard on the driver side, near the door | Pull the trim cover outward, it is held by plastic clips only, no tools needed on most cars |
Finding the official fuse legend
Do not rely on generic amperage charts found online, they frequently do not match your exact engine and trim. The trustworthy source is printed in two places: a diagram on the underside of each fuse box lid, and a dedicated electrical chapter in the owner's manual that lists every circuit by number. Always cross-check the lid diagram against the manual before pulling a fuse, since running changes can shift a circuit to a different slot mid-production.
Fuses that most commonly blow, by function
- Cigarette lighter / 12V accessory outlet: stops charging phones or powering accessories, usually from a plugged-in device drawing too much current or a short in an aftermarket adapter.
- Radio / infotainment system: screen goes black or the unit will not power on, often tied to a shared circuit with other accessories.
- Interior lighting: dome light, glovebox light, or footwell lights stop working while everything else is fine.
- Blower motor (HVAC fan): air stops moving through the vents even though the climate controls still respond, commonly from a worn blower motor drawing excess current.
- Fuel pump relay circuit: the engine cranks but will not start, or stalls and will not restart, because the pump has lost power.
Checking and replacing a fuse
Pull the fuse straight out using the small plastic tweezers usually clipped inside the fuse box lid. Hold it up to the light and look at the thin metal strip inside, if it is broken or the plastic body is scorched, it has blown. For a more certain check, use a test light or multimeter across the two prongs with the circuit powered, no continuity means the fuse is bad. Replace it only with a fuse of the identical amp rating shown on the lid diagram, never a higher rating, since the fuse is sized to protect the wiring, not just the component.
When a fuse keeps blowing
A fuse that blows once from a temporary overload is normal. A fuse that blows again immediately after replacement points to a short circuit or failing component downstream, and repeatedly forcing in a higher-rated fuse to keep it working risks a wiring fire. In these cases a scan tool that reads stored fault codes can point straight at the affected circuit or module long before the wiring has to be traced by hand, which is faster and safer than guesswork.
Summary
| Market | Not sold in US/Canada; Brazil and Latin America are the primary reference markets |

| Engine bay box location | Next to the battery, driver side of the engine compartment |
| Cabin box location | Driver-side end of the dashboard, near the door |
| Trunk fuse box | None on the Duster |
| Official fuse legend source | Diagram on the fuse box lid + owner's manual electrical chapter |
| Fuse replacement rule | Match the amp rating exactly, never install a higher rating |

Frequently asked questions
Where is the fuse box on a Renault Duster?
The Renault Duster has two fuse and relay boxes: one under the hood next to the battery on the driver side, covering the engine and main power circuits, and one inside the cabin at the driver-side end of the dashboard near the door, covering interior electronics and accessories. There is no separate fuse box in the trunk.
How do I open the Duster's interior fuse box?
Pry the small trim cover at the driver-side end of the dashboard outward, it is held on by plastic clips and usually comes off with your fingertips or a flat trim tool, no screws involved on most model years.
Why does my Duster's cigarette lighter or 12V outlet keep blowing a fuse?
This is usually caused by a device or aftermarket accessory plugged into the outlet drawing more current than the circuit is rated for, or a short inside a cheap adapter. Replace the fuse with the exact same amp rating shown on the fuse box lid and stop using the offending accessory, if it blows again right away have the circuit checked for a short.
Where can I find the exact fuse amp ratings for my Renault Duster?
The reliable source is the diagram printed on the inside of each fuse box lid, cross-checked with the electrical section of your owner's manual, since exact positions and amperages can vary by model year and engine and are not safe to guess from generic online charts.
