Replace Blown Fuses: 2015 Hyundai Sonata Fuses Diagram
Maintaining optimal electrical functionality in the 2015 Hyundai Sonata requires replacing blown fuses in an effective manner. The fuse diagram is a vital reference point for determining which particular fuse is connected to a faulty component. It is usually found in easily accessible regions such as the engine compartment or interior. A certain amperage rating is assigned to each fuse to protect against overloads and malfunctions. Fuse pullers or pliers must be used to gently remove a malfunctioning fuse—which can be identified by a broken wire or discoloration—and replace it with a new fuse of the same amperage. A dependable 2015 Hyundai Sonata can be ensured by routinely checking and replacing fuses in line with the supplied schematic, which helps to minimize potential electrical problems and enhances the driving experience.

FUSES
A vehicle’s electrical system is protected from electrical overload damage by fuses. This vehicle has 2 (or 3) fuse panels, one located in the driver’s side panel bolster, 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 or broken. If the electrical system does not work, first check the driver’s side fuse panel. Before replacing a blown fuse, turn the engine and all switches off, and then disconnect the negative battery cable. Always replace a blown fuse with one of the same rating. If the replacement fuse blows, this indicates an electrical problem. Avoid using the system involved and immediately consult an authorized HYUNDAI dealer.
Information
Three kinds of fuses are used: blade type for lower amperage rating, cartridge type, and fusible link for higher amperage ratings.
WARNING
NEVER replace a fuse with anything but another fuse of the same rating.
- A higher capacity fuse could cause damage and possibly cause a fire.
- Do not install a wire or aluminum foil instead of the proper fuse – even as a temporary repair. It may cause extensive wiring damage and possibly a 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.
Instrument Panel Fuse Replacement
- Turn the engine off.
- Turn all other switches OFF.
- Open the fuse panel cover.
- Refer to the label on the inside of the fuse panel cover to locate the suspected fuse location.
- Pull the suspected fuse straight out. Use the removal tool provided in the engine compartment fuses panel.
- Check the removed fuse; replace it if it is blown. Spare fuses are provided in the instrument panel fuse panels (or 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.
In an emergency, if you do not have a spare fuse, use a fuse of the same rating from a circuit you may not need for operating the vehicle, such as the cigarette lighter fuse. If the headlamps or other electrical components do not work and the fuses are OK, check the fuse panel in the engine compartment. If a fuse is blown, it must be replaced with the same rating.
Fuse switch
Always, place the fuse switch to the ON position. If you move the switch to the OFF position, some items such as the audio system and digital clock must be reset and the smart key may not work properly.
Information
If the fuse switch is OFF, the above message will appear.
NOTICE
- Always place the fuse switch in the ON position while driving the vehicle.
- Do not move the transportation fuse switch repeatedly. The fuse switch may be damaged.
Engine Compartment Panel Fuse Replacement
- Turn the engine off.
- Turn all other switches OFF.
- Remove the fuse panel cover by pressing the tap and pulling 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.
Main fuse
If the main fuse is blown, it must be removed as follows:
- Turn off the engine.
- Disconnect the negative battery cable.
- Remove the fuse panel cover by pressing the tab and pulling it up.
- 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.
Information
If the main fuse is blown, consult an authorized HYUNDAI dealer.
Multi fuse
If the multi fuse is blown, it must be removed as follows:
- Turn off the engine.
- Disconnect the negative battery cable.
- Remove the fuse panel cover by pressing the tab and pulling it up.
- 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.
Information
If the multi fuse is blown, consult an authorized HYUNDAI dealer.

FAQs
Blown fuses can cause electrical components to malfunction or stop working altogether, affecting various systems in your vehicle.
A blown fuse can usually be identified by a broken filament visible through the fuse’s transparent housing or with the aid of a multimeter to check for continuity.
The 2015 Hyundai Sonata typically uses blade-type fuses, which are commonly found in modern vehicles.
The fuse box is usually located either under the dashboard on the driver’s side or in the engine compartment.
It’s crucial to use the correct type and amperage rating of fuse specified for your Sonata to avoid damaging electrical components.
Use a fuse puller tool or a pair of needle-nose pliers to carefully grasp and pull the fuse straight out of its slot.
Yes, you can usually see a break in the metal filament inside a blown fuse.
Make sure the vehicle is turned off and the key is removed from the ignition before working with fuses to avoid electrical shock or damage.
You can use a fuse tester or multimeter to check for continuity without removing the fuse from its socket.
No, it’s crucial to replace a fuse with one of the same amperage rating to avoid damaging the electrical system.
If a fuse keeps blowing, it indicates a larger electrical issue that should be diagnosed and repaired by a professional.
It’s a good idea to check the fuses periodically, especially if you notice any electrical issues with your vehicle.
Replacing a fuse is a relatively simple task that most car owners can do themselves with the proper tools and caution.
