Fiat Argo Fuse Box: Location & Guide
TL;DR
The Argo has an engine-bay fuse/relay box by the battery and an in-cabin fuse panel behind a small cover left of the steering wheel; check the lid diagram in your own car for exact positions since these vary by engine/trim.
Where the Fiat Argo fuse boxes are located
Every Fiat Argo built since its 2017 launch uses the same basic two-box layout shared with the related Fiat Cronos. The engine-bay box sits in the front corner of the engine compartment next to the battery, and the interior box is tucked into the end of the dashboard on the driver's side, near the door hinge, hidden by a small plastic cover you unclip by hand. There is no fuse box under the rear seat or in the trunk area on this model.
How to open each box
The engine-bay cover is usually held by one or two plastic clips or a quarter-turn fastener - press or twist and lift straight up. Some model years use a small lever or tab you pull toward you before lifting the lid. The interior cover is a snap-fit trim piece; pull it toward you from the edge nearest the door, working your fingers gently under the lip until the clips release. Avoid prying with a screwdriver, which can crack the plastic.
Finding the official fuse legend
Fiat does not print a universal fuse map because assignments shift by engine (Firefly 1.0 or 1.3 GSR), transmission (manual or CVT), and equipment level. The authoritative source is always the diagram molded or printed on the inside of each fuse box lid, plus the electrical system chapter of the owner's manual, which explains the legend symbols and lists spare fuse locations.
Fuses that most commonly cause complaints
By function, the circuits owners most often ask about are the 12V accessory outlet/cigarette lighter (stops charging phones or dash cams), the radio/infotainment unit (screen goes dark or won't power on), interior dome and courtesy lights, the blower motor for heating and air conditioning (fan stops on all speeds), and the fuel pump relay circuit (car cranks but won't start). Each of these is a separate, individually numbered fuse or relay on the lid diagram - identify it by its labeled function, not by memorizing a position number, since that number can differ between build years.
Checking and replacing a fuse
Pull the suspect fuse with the plastic tweezers usually clipped inside the box lid and look at the thin metal strip inside: if it is broken or blackened, it is blown. For certainty, use a test light or multimeter across the fuse terminals with the ignition on - no continuity means it is blown. Replace it only with a fuse of the identical amperage rating printed on the fuse body and on the lid diagram; never fit a higher-rated fuse, as that removes the protection the circuit needs.
When a fuse keeps blowing
A fuse that blows again shortly after replacement is a warning sign of a short circuit or failing component downstream, not a fuse defect. Repeated blows on the same circuit should prompt a proper diagnostic scan for stored fault codes, which can point directly to the wiring section or component at fault instead of guessing - this is exactly the kind of deeper check worth running before swapping fuses again and again.
| Generation / years | Fuse box | Location | How to access |
|---|---|---|---|
| 2017-present (all Argo) | Engine-bay fuse and relay box | Front of engine compartment, next to the battery, driver side | Unclip or unscrew plastic lid; some years use a pull tab or lever |
| 2017-present (all Argo) | Interior fuse panel | End of dashboard, driver side, near the door hinge | Pull off the small snap-fit trim cover by hand |
Summary
| Engine-bay fuse box location | Front of engine compartment, next to the battery, driver side |
|---|---|
| Interior fuse box location | End of dashboard, driver side, near door hinge, behind snap-fit cover |
| Trunk fuse box | None on this model |
| Official fuse legend source | Diagram printed on the inside of each fuse box lid + owner's manual electrical chapter |
| Most commonly blown fuses (by function) | 12V outlet/cigarette lighter, radio/infotainment, interior lights, blower motor, fuel pump relay |
| How to test a fuse | Visual check of the metal strip, or test light/multimeter across terminals with ignition on |
| Replacement rule | Match the exact amp rating printed on the fuse - never install a higher rating |

Frequently asked questions
Where is the main fuse box on a Fiat Argo?
The Fiat Argo has two fuse boxes: one in the engine bay next to the battery on the driver side, covered by a plastic lid held with clips or a twist fastener, and a second one inside the cabin at the driver-side end of the dashboard, hidden behind a small snap-fit trim cover. There is no trunk-mounted fuse box on this model.
Why does my Fiat Argo cigarette lighter or USB port stop working?
A dead 12V accessory outlet or USB port on the Argo is almost always a blown fuse dedicated to that circuit, commonly caused by a phone charger or accessory left plugged in or a short in an aftermarket gadget. Check the fuse listed for the accessory/power outlet circuit on your fuse box lid diagram, confirm it is blown with a test light, and replace it with a fuse of the same amp rating - never a higher one.
How do I know which fuse controls the radio or blower motor on my Argo?
Open the relevant fuse box lid (engine bay or interior panel) and read the printed diagram on its underside, which labels each fuse by the circuit it protects, such as radio/infotainment or blower motor/HVAC fan. Because these assignments can differ by engine and trim, always check your own vehicle's lid diagram or owner's manual rather than a generic online fuse map.
My Fiat Argo fuse keeps blowing again after I replace it - what does that mean?
A fuse that blows repeatedly, even after being replaced with the correct amperage, indicates an underlying short circuit or a failing component on that circuit rather than a bad fuse. In this situation, get the car's stored fault codes read with a diagnostic scanner, since they usually point to the exact circuit or component causing the short, saving you from replacing fuses over and over without fixing the real problem.
