Hyundai Santa Fe Fuse Box: Location & Guide
TL;DR
The Santa Fe has an engine-bay fuse/relay box near the battery and an interior fuse panel by the driver's left knee; both box lids show the fuse map, confirmed against the owner's manual for your exact year.
Where the Santa Fe fuse boxes are located
Across every generation the Santa Fe uses a two-box layout. The engine bay fuse and relay box sits at the front of the engine compartment, usually near the battery or the front corner of the bay, and holds the higher-amperage fuses and relays for things like the cooling fan, headlights, and fuel pump relay. The interior fuse panel is mounted low on the driver's side, to the left of the steering wheel under the dash, and covers the fuses for the cabin electronics, lighting, and accessory circuits.
| Generation / years | Fuse box | Location | How to access |
|---|---|---|---|
| NF (2001-2006) | Engine bay box | Front of engine compartment, near battery | Lift the plastic lid, releasing the side clips |
| NF (2001-2006) | Interior panel | Driver's side, lower dash near door | Pull the small cover panel by hand |
| CM (2007-2012) | Engine bay box | Front-left of engine compartment | Unclip the lid tabs and lift |
| CM (2007-2012) | Interior panel | Left of the steering wheel, below the dash | Open the hinged or snap-fit cover |
| DM (2013-2018) | Engine bay box | Front of engine bay, near the battery | Release the latch or side clips and lift the lid |
| DM (2013-2018) | Interior panel | Driver's footwell area, left of steering column | Pull the cover panel toward you by its edge |
| TM (2019-2023) | Engine bay box | Front of engine compartment | Unclip and lift the lid |
| TM (2019-2023) | Interior panel | Lower dash, driver's side | Open the small hinged cover |
| MX5 (2024-present) | Engine bay box | Front of engine bay (exact spot varies by powertrain, including hybrid variants) | Release the lid clips |
| MX5 (2024-present) | Interior panel | Driver's side lower dash | Unclip the cover panel |
Where the official fuse legend lives
Do not rely on memory or generic charts for exact fuse positions and amperages: the printed diagram on the underside of each box lid is the authoritative source for your specific car, and the owner's manual electrical section repeats and expands on it. Layouts and amp ratings can differ by engine, trim, and even mid-cycle running changes within the same generation, so always verify against your own vehicle before buying a replacement fuse.
Fuses that commonly cause trouble
Owners most often report issues traced to a handful of circuits: the cigarette lighter / 12V power outlet fuse (outlet stops charging phones or accessories), the radio / infotainment fuse (screen stays blank or the system won't power on), the interior lighting fuse (dome or map lights go dark), the blower motor fuse (HVAC fan stops moving air on any speed), and the fuel pump relay circuit (car cranks but won't start, or stalls and won't restart). These symptoms point to the function affected, not a specific numbered fuse, since numbering varies by year.
Checking and replacing a fuse
Pull the suspect fuse straight out with the plastic fuse puller usually clipped inside the box lid and look at the thin metal element inside: a blown fuse shows a visibly broken or melted strip. If it looks intact but you still suspect it, a simple test light or multimeter across the two prongs with the key on will confirm continuity. Replace only with a fuse of the same amperage rating printed on the original - never a higher rating, since that removes the protection the circuit was designed with and risks wiring damage or fire.
When a fuse keeps blowing
A fuse that blows once and then behaves normally for a long time is usually incidental. A fuse that blows again shortly after replacement almost always signals a short circuit or overloaded component downstream, not a weak fuse. In that case, stop replacing fuses and have the circuit diagnosed properly - pulling stored diagnostic trouble codes from the vehicle's control modules is often the fastest way to identify which component or wiring section is at fault before more damage or a fire risk develops.

Frequently asked questions
Where is the interior fuse box on a Hyundai Santa Fe?
On every Santa Fe generation (NF, CM, DM, TM, and MX5) the interior fuse panel is mounted low on the dash on the driver's side, to the left of the steering wheel. It sits behind a small hinged or clip-in cover that either flips down or pulls off by hand; the fuse map is printed on the inside of that cover.
Where is the engine bay fuse box on a Santa Fe?
The engine bay fuse and relay box is at the front of the engine compartment, generally near the battery. The lid lifts off after releasing side clips or a latch, and it holds the higher-current fuses and relays such as those for the cooling fan and headlights.
Why does my Santa Fe's cigarette lighter or 12V outlet fuse keep blowing?
A 12V outlet or cigarette lighter fuse that blows repeatedly usually means a plugged-in accessory (phone charger, inflator, dash cam) is drawing too much current or has a short in its plug or cable, not that the fuse itself is defective. Replace the fuse with the same amp rating and test with the accessory unplugged; if it blows again with nothing plugged in, there is a wiring short that needs diagnosis rather than another fuse swap.
How do I know if a Santa Fe fuse is blown?
Pull the fuse using the small plastic puller clipped inside the fuse box lid and look at the thin wire loop inside it: a blown fuse shows a visibly broken or melted strip. If it looks fine but you still suspect it, touch a test light or multimeter probe to each prong with the ignition on to confirm whether current passes through.
