2019 Hyundai Nexo Fuse Box Diagram | Replacing Fuses Guide
Your 2019 Hyundai Nexo comes equipped with a fuse box that plays a crucial role in safeguarding various electrical components within your vehicle. Fuses act as protective barriers, preventing electrical overloads that could potentially damage critical systems. In the event of a malfunction, knowing how to replace a fuse is essential for maintaining the smooth operation of your vehicle. Located within your Hyundai Nexo, the fuse box houses a series of fuses, each designated for a specific circuit. These circuits control various functions, ranging from interior lighting to engine management systems. To effectively address electrical issues, it’s essential to comprehend the layout of the fuse box and the purpose of each fuse.
Referencing a fuse box diagram is instrumental in identifying the location and amperage rating of each fuse. This diagram provides a visual representation of the fuse box layout, allowing you to pinpoint the fuse corresponding to the malfunctioning component. With this information, you can swiftly locate and replace the faulty fuse, restoring functionality to the affected system.

Fuse
A vehicle’s electrical system is pro-tected 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 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 ratings, cartridge type, and multi fuse 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 aluminium 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 provided 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 headlamps 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.
