How do you remove the fuse from a Hyundai?
To remove a fuse from a Hyundai, follow these steps:
Turn off the vehicle: Always make sure the ignition is off and the key is removed to avoid any electrical shock or short circuit.
Locate the fuse box: Hyundai vehicles usually have two fuse boxes—one under the dashboard (driver’s side) and one in the engine compartment.
Open the fuse box cover: Carefully open the fuse box cover. There’s usually a diagram on the inside of the cover showing the fuse layout and functions.
Identify the fuse: Use the diagram to locate the specific fuse you want to remove.
Use a fuse puller or tweezers: Most Hyundai vehicles come with a plastic fuse puller, usually clipped inside the fuse box cover. Use it or a pair of plastic-tipped tweezers to grip the fuse.
Pull the fuse straight out: Gently but firmly pull the fuse straight out. Avoid wiggling too much to prevent damage to the fuse or the fuse socket.
Inspect or replace as needed: Check the fuse for a broken or burnt filament. Replace it with a fuse of the same amperage if necessary.
Reinstall the fuse (if needed): Push it back into place firmly if you’re reinstalling the same fuse.
Close the fuse box cover: Once done, snap the cover back into place securely.

Frequently Asked Questions
Where is the 12V battery in the Hyundai Nexo?
The 12V lithium-ion polymer auxiliary battery in the Hyundai Nexo is located in the trunk area, positioned just in front of the high-voltage battery. This battery powers the vehicle’s accessories and other auxiliary systems.
According to the Nexo Emergency Response Guide, it is a separate 12V lithium-ion polymer battery, distinct from the main high-voltage system.
What is the problem with the fuel cell in the Hyundai Nexo?
The issue with the fuel cell in the Hyundai Nexo involves a faulty pressure relief device (TRPD) that can fail and lead to a hydrogen leak, creating a potential fire hazard. This device is meant to release gas and prevent excessive pressure inside the fuel tank. However, its glass bulb can crack prematurely, allowing hydrogen to escape—even when the vehicle is parked.
Always consult your Hyundai owner’s manual for fuse box locations and specifications for your specific model.
