Renault Sandero Fuse Box: Location & Guide
TL;DR
Sandero fuses live in an engine-bay box (battery area) and a dash-mounted interior box; both lids show the official legend, and the owner's manual repeats it.
Where the Sandero fuse boxes are located
Across the generations sold in Latin America (including Brazil, where the Sandero is built and sold locally), the layout is consistent in principle even if exact fuse counts differ: an engine-bay fuse/relay box sits near the battery on the passenger side of the bay, under a plastic cover secured by clips or a quarter-turn latch, and a passenger-compartment fuse box sits at the left edge of the dashboard (driver's side, near the door hinge) or tucked under a small trim panel just left of the steering column, depending on the model year. Some facelifted units also route certain accessory fuses behind the glovebox. There is no separate trunk fuse box on the Sandero hatchback.
| Generation / years | Fuse box | Location | How to access |
|---|---|---|---|
| Sandero I (approx. 2007-2014, Brazil/LatAm) | Engine bay | Next to the battery, passenger side of the engine bay | Unclip or lift the black plastic cover; no tools usually needed |
| Sandero I (approx. 2007-2014) | Interior | Left end of dashboard, near driver door | Pull or unclip the small trim cover by hand |
| Sandero II / Stepway (approx. 2014-2019) | Engine bay | Battery area, engine bay | Unclip cover, sometimes one retaining screw |
| Sandero II / Stepway (approx. 2014-2019) | Interior | Dash edge near driver's knee, or under glovebox | Unclip cover or remove glovebox liner |
| Sandero III (2020-present, Brazil/LatAm) | Engine bay | Battery area, engine bay | Unclip plastic cover |
| Sandero III (2020-present) | Interior | Left dash edge near door, behind small panel | Pry gently with a flat trim tool or by hand at the panel edge |
Reading the fuse legend
The inside of each fuse box lid has a printed diagram (icons plus amperage) matching the fuses beneath it. The owner's manual has an identical diagram in the electrical/fuses chapter, useful if the printed lid legend has faded or is missing. Always match the diagram to your exact car since running production changes can shuffle which circuit sits in which slot.
Fuses that commonly blow, by function
- Cigarette lighter / 12V accessory outlet: often blows from phone chargers, tire inflators, or dash cams pulling more current than the fuse allows; symptom is total loss of power at the outlet with everything else working.
- Radio / infotainment: a blown fuse here kills the screen and audio but leaves climate and lights working; a screen that reboots repeatedly before going dark can also point to a wiring short rather than a simple blown fuse.
- Interior lighting (dome light, glovebox light): low-current circuit, but a short from a pinched wire behind a trim panel can blow it repeatedly.
- Blower motor (heater/AC fan): a fuse that blows only on higher fan speeds often means the blower motor itself is dragging (worn bearings) and drawing excess current.
- Fuel pump relay circuit: if this fuse blows, the car will crank but not start, or will die while driving; a fuse that blows again immediately after replacement is a strong sign of a shorted fuel pump or wiring, not a random one-off failure.
Checking and replacing a fuse safely
Turn off the ignition first. Pull the suspect fuse using the small plastic tweezers usually clipped inside the fuse box lid, then look at the thin metal strip inside: if it is visibly separated or the plastic body is discolored/melted, it has blown. When unsure, a test light or multimeter across the fuse terminals with the ignition on confirms continuity. Always replace with the same amperage rating printed on the lid diagram or the original fuse; installing a higher-rated fuse will not fix the problem and can allow wiring to overheat before the fuse ever trips.
When a fuse keeps blowing
A single blown fuse is usually a one-time overload. A fuse that blows again right after replacement, or blows repeatedly under normal use, points to a short circuit somewhere in that circuit's wiring or a failing component drawing too much current, and simply fitting fuse after fuse will not solve it. In these cases, pulling stored diagnostic trouble codes with a code reader narrows down which module or circuit is at fault far faster than tracing wiring by hand, and is the recommended next step before further fuse replacement.
Summary
| Engine-bay fuse box location | Near battery, passenger side of engine bay |
|---|---|
| Interior fuse box location | Left dash edge near driver's door (or behind glovebox on some years) |
| Trunk fuse box | Not present on the Sandero hatchback |
| Official fuse legend | Printed on box lid; duplicated in owner's manual fuses chapter |
| Most commonly blown fuses | 12V outlet, radio/infotainment, interior lights, blower motor, fuel pump relay |
| Fuse check method | Visual inspection of metal strip, or test light/multimeter with ignition on |
| Repeat blowing fuse | Suggests a short or failing component; check stored fault codes |

Frequently asked questions
Where is the fuse box on a Renault Sandero?
The Renault Sandero has two fuse boxes: one in the engine bay near the battery (under a clip-on plastic cover) and one inside the cabin at the left edge of the dashboard near the driver's door, sometimes accessed behind the glovebox on later models. There is no separate fuse box in the trunk.
How do I know which fuse to check for a blown 12V outlet or radio?
Open the fuse box lid nearest the affected system (engine bay for power/relay items, interior dash box for radio, lights, and 12V outlet) and match the printed diagram on the lid to the circuit icon for the accessory outlet or radio; the owner's manual repeats the same diagram if the lid legend is worn.
Can I put a higher-amp fuse in my Sandero if it keeps blowing?
No. Always replace a blown fuse with one of the exact same amperage shown on the fuse box lid diagram or owner's manual. A higher-rated fuse lets more current flow than the wiring is designed for, which can cause overheating or a wiring fire instead of protecting the circuit.
Why does the same fuse on my Sandero keep blowing after I replace it?
A fuse that blows again immediately after replacement, or blows repeatedly, is not a random failure — it usually means there is a short circuit or a failing component (such as a worn blower motor or a shorted fuel pump) drawing excess current in that circuit. Reading stored fault codes with a scan tool is the fastest way to identify the affected circuit before replacing more fuses.
