Fuses and Fuse Box
FUSES
- A vehicle’s electrical system is protected from electrical overload dam-age by fuses.
- This vehicle has 2 (or 3) fuse panels, one located in the driver’s side panel bolster, the other in the fuel cell power module 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 vehicle and all switch-es off, and then disconnect the neg-ative 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 multi fuse for higher amperage ratings.
WARNING
NEVER replace a fuse with any-thing 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.
NOTICE
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 vehicle 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 fuel cell power module compartment fuse panel.
- Check the removed fuse; replace it if it is blown. Spare fuses are pro-vided in the instrument panel fuse panels (or in the fuel cell power module 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.
If the headlights or other electrical components do not work and the fuses are OK, check the fuse panel in the fuel cell power module compartment. If a fuse is blown, it must be replaced with the same rating.
Fuel Cell Power Module Compartment Panel Fuse Replacement
Blade / Cartridge type 
- Turn the vehicle 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 motor 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
- After checking the fuse box in the fuel cell power module compartment securely close the fuse box cover inside the motor compartment, until it clicks.
- If the fuse box is not closed properly, water may leak in side, possibly causing a malfunction with the electrical system.
Multi Fuse
If the multi fuse is blown, it must be removed as follows
- Turn the vehicle off.
- Disconnect the negative battery connector located on the trunk.
- 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
The 2023 Hyundai Nexo Fuel Cell’s fuse box is a storage space that holds a variety of fuses, which are safety gadgets made to guard the car’s electrical circuits from overloads and short circuits.
In the 2023 Hyundai Nexo Fuel-Cell, the fuse box is normally found inside the car, frequently next to the dashboard or underneath the steering wheel.
Consult your vehicle’s owner’s manual for further information on how to access the fuse box. For the fuse box in the engine compartment, you often need to open the hood, and for the fuse box in the cabin, you usually need to open a panel inside.
Fuses in the Hyundai Nexo Fuel-Cell of 2023 safeguard a number of electrical parts and circuits by shutting off the circuit in the event of an overload or short circuit. This guards against harm to the wiring and electronics of the car.
The associated electrical component might not function if a fuse blows. Fuse testers or visual inspection for broken wires are two options. Always refer to your owner’s handbook to determine the replacement fuse’s amperage rating
In the 2023 Hyundai Nexo Fuel-Cell, a blown fuse may usually be replaced. Use the proper replacement fuse and follow the exact process as outlined in your owner’s manual.
The 2023 Hyundai Nexo Fuel-Cell typically simply requires your hands or a set of needle-nose pliers to change a fuse.
Fuses are often not covered by the vehicle’s warranty because they are regarded as wear-and-tear parts.
If a replacement fuse continues to blow, there can be a deeper electrical problem. To identify and resolve the issue, it is advised to have the car inspected by a skilled expert.
No, a blown fuse must be replaced with a new one that has the same amperage rating. Using a higher-amp fuse could result in a fire or electrical harm.
Using a lower-amp fuse may prevent immediate damage, but it may leave the circuit under-protected and cause additional problems. Use the appropriate amperage fuse as soon as you can.
If spare fuses are offered, examine if they are listed in the owner’s manual for your car. It’s a good idea to maintain a range of extra fuses in your car just in case.
uses typically have a long lifespan, but if you’re having electrical problems, it’s a good idea to inspect them. By doing routine maintenance inspections, you can make sure they are operating properly.
Fuse modifications or fuse additions can lead to electrical issues, void your warranty, and possibly pose safety risks. It is advised to refrain from making any changes.
Consult the owner’s manual or a trained Hyundai technician for comprehensive information on the fuses and fuse box in the 2023 Hyundai Nexo Fuel-Cell. They can answer all of your questions and offer precise advice.
