Fuses
A vehicle’s electrical system is protected from electrical overload damage by fuses. This vehicle has 2 fuse panels, one located in the driver’s side panel bolster, and the other in the engine compartment near the battery. If any of your vehicle’s lights, accessories, or controls do not work, check the appropriate circuit fuse. If a fuse has blown, the element inside the fuse will be melted. If the electrical system does not work, first check the driver’s side fuse panel. Always replace a blown fuse with one of the same rating. Before replacing an open fuse, disconnect the negative battery cable. If the replacement fuse blows, this indicates an electrical problem. Avoid using the system involved and immediately consult an authorized HYUNDAI dealer. Three kinds of fuses are used: blade type for lower amperage ratings, cartridge type, and multi fuse for higher amperage ratings.
WARNING
Fuse replacement
- Never replace a fuse with anything but another fuse of the same rating.
-
A higher capacity fuse could cause damage and possibly a fire.
- Never install a wire or aluminum foil instead of the proper fuse – even as a temporary repair. It may cause extensive wiring damage and a possible fire.
CAUTION
Do not use a screwdriver or any other metal object to remove fuses because it may cause a short circuit and damage the system.
NOTICE
The actual fuse/relay panel label may differ from the equipped items.
CAUTION
-
When replacing an open fuse or relay with a new one, make sure the new fuse or relay fits tightly into the clips. The incomplete fastening fuse or relay may cause the vehicle wiring and electric systems damage and a possible fire.
-
Do not remove fuses, relays, and terminals fastened with bolts or nuts. The fuses, relays, and terminals may be fastened incompletely, and it may cause a possible fire. If fuses, relays, and terminals fastened with bolts or nuts are open, consult with an authorized HYUNDAI dealer.
-
Do not input any other objects except fuses or relays into fuse/relay terminals such as a driver or wiring. It may cause contact failure and system malfunction.
Instrument Panel Fuse Replacement
- Turn the ignition switch and all other switches off.
- Open the fuse panel cover.
- Pull the suspected fuse straight out. Use the removal tool provided in the engine compartment fuse panel.
- Check the removed fuse; replace it if it is blown.
- Push in a new fuse of the same rating, and make sure it fits tightly in the clips.
If it fits loosely, consult an authorized HYUNDAI dealer.
If you do not have a spare, use a fuse of the same rating from a circuit you may not need for operating the vehicle, such as the cigar lighter fuse.
If the headlights or other electrical components do not work and the fuses are OK, check the fuse block in the engine compartment. If a fuse is blown, it must be replaced.
Fuse switch
Always, put the mode switch at the ON position.
If you move the switch to the OFF position, some items such as the audio and digital clock must be reset and the transmitter (or smart key) may not work properly.
CAUTION
Always place the fuse switch in the ON position while driving the vehicle.
Engine Compartment Panel Fuse Replacement
- Turn the ignition switch and all other switches off.
- Remove the fuse box cover by pressing the tab and pulling it up.
- Check the removed fuse; replace it if it is blown. To remove or insert the fuse, use the fuse puller in the engine compartment fuse panel.
- Push in a new fuse of the same rating, and make sure it fits tightly in the clips. If it fits loosely, consult an authorized HYUNDAI dealer.
CAUTION
Always, put the mode switch at the ON position.
If you move the switch to the OFF position, some items such as the audio and digital clock must be reset and the transmitter (or smart key) may not work properly.
Multi fuse
If the multi fuse is blown, it must be removed as follows:
- Disconnect the negative battery cable.
- Remove the bolts shown in the picture above.
- Replace the fuse with a new one of the same rating.
- Reinstall in the reverse order of removal.
Main fuse
If the main fuse is blown, it must be removed as follows
-
Disconnect the negative battery cable.
-
Remove the nuts shown in the picture above.
-
Replace the fuse with a new one of the same rating.
-
Reinstall in the reverse order of removal.

How to replace Fuse of the 2015 Hyundai Santa FE
Replacing fuses in a 2015 Hyundai Santa Fe involves a standard process. Here’s a general guide:
Materials:
- The new fuse of the correct amperage.
- Fuse puller or needle-nose pliers.
Instructions:
- Locate the Fuse Box: The fuse box in the Hyundai Santa Fe is typically located in one of two places. The primary fuse box is usually found under the dashboard on the driver’s side, to the left of the steering wheel. There might also be a secondary fuse box under the hood of the car, usually near the battery or firewall.
- Identify the Blown Fuse: Use the fuse diagram located on the inside of the fuse box cover to identify which fuse needs to be replaced. The diagram will label each fuse and its corresponding function.
- Turn Off the Ignition: Before you start working on the fuses, ensure the ignition is turned off to prevent any electrical mishaps.
- Remove the Fuse: Use a fuse puller tool or a pair of needle-nose pliers to carefully remove the blown fuse. Grip the fuse firmly and pull it straight out of its slot.
- Check the Fuse: Visually inspect the fuse to confirm that it is blown. If the metal strip inside the fuse is broken or appears burnt, then it needs to be replaced.
- Replace the Fuse: Insert a new fuse of the same amperage rating into the slot. Make sure it is pushed in securely.
- Test the Circuit: After replacing the fuse, turn the ignition back on and test the circuit to ensure that the issue has been resolved. For example, if you were replacing a fuse related to the headlights, check if the headlights now function properly.
- Replace the Fuse Box Cover: Once you’ve confirmed that the new fuse is working correctly, replace the fuse box cover and secure it in place.
- Dispose of Old Fuse: Safely dispose of the old, blown fuse. You can simply discard it in the trash or recycle it if appropriate
Tips:
- Always use a fuse with the correct amperage rating to prevent electrical issues or damage to the vehicle.
- If a fuse blows repeatedly, it may indicate an underlying electrical problem and professional assistance may be needed.
FAQs
The fuses and switches in a car’s electrical system are shown on a fuse box diagram, along with information about where they are located and what they do.
The fuse box in a 2015 Hyundai Santa Fe is typically located in the engine compartment or under the dashboard on the driver’s side.
In the Hyundai Santa Fe, fuses protect electrical parts like lights, radios, power windows, and other items from damage caused by electrical surges, among other things.
A blown fuse can usually be identified by a visual inspection of the metal strip inside the fuse, which will be broken if the fuse is blown.
In the 2015 Hyundai Santa Fe, the fuses are different sizes based on the electrical part they protect. Mini, normal, and maxi fuses are all common sizes.
Relays in the Hyundai Santa Fe help control high-current circuits, serving as switches that are activated by low-current signals from the vehicle’s control modules.
Fuses are usually easy for the owner to change because they are made to be serviceable by the user. But replacing relays may need more mechanical know-how and is usually best left to experts.
It’s essential to disconnect the vehicle’s battery before working with fuses and relays to avoid the risk of electrical shock or damage to sensitive electronic components.
Signs of a malfunctioning relay may include intermittent or complete failure of electrical components controlled by that relay, such as the headlights or windshield wipers.
Yes, using a fuse with an incorrect rating can lead to electrical system damage or even fire hazards. It’s crucial to always replace fuses with the correct rating specified by the manufacturer.
Yes, aftermarket parts like amplifiers, lighting kits, or trailer wire harnesses may need extra fuses to protect both the part and the car’s electrical system.
Fuses should be inspected regularly as part of routine vehicle maintenance or whenever an electrical issue arises. Visual inspection can quickly identify blown fuses.
Yes, keeping spare fuses and relays in the vehicle’s glove box or toolkit can be beneficial in case of an emergency or unexpected electrical failure.
