2019 Hyundai Tucson Replacing Fuses | Fuse Diagrams
Here is the definitive guide to helping you become an expert fuse replacement technician for your 2019 Hyundai Tucson. Fuses are crucial parts of the electrical system in every car because they protect different circuits from harm from electrical overloads. Even though they are meant to survive, fuses occasionally blow, which can cause systems or other parts of your car to fail. Locating and replacing fuses is an essential skill for each owner of an automobile. This tutorial is designed exclusively to provide Hyundai Tucson owners with the knowledge and self-assurance they need to handle fuse replacements successfully.

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, 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 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
Four kinds of fuses are used: blade type For lower amperage rating, cartridge type/Multi fuse/Battery fuse terminal 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.
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 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 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 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 in 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 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.
CAUTION
After checking the fuse box in the engine compartment securely close the fuse box cover inside the engine compartment, until it clicks.
If the fuse box is not closed properly, water may leak inside, possibly causing a malfunction with the electrical system.
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
In the engine compartment of a 2019 Hyundai Tucson, the fuse box is normally found. It can also be located beneath the steering wheel or in the dashboard on the driver’s side.
For further information on how to access the fuse box and its precise location. Typically, in order to reach the fuses, you might have to unscrew a cover or open a panel.
Usually, all you’ll need is a fuse puller tool that comes with the fuse box or a pair of needle-nose pliers.
The electrical component that each fuse protects determines the ampere rating of the fuse. For precise ratings, see the fuse box lid or your owner’s handbook.
A clearly broken wire within the fuse is typically how you can tell whether it has blown. Furthermore, the fuse’s metal strip may seem melted or disconnected.
Get a replacement fuse with the same ampere rating and replace the blown one. Using the appropriate rating is crucial to prevent electrical component damage.
No, utilizing a fuse with a greater ampere rating could cause harm to your electrical system or perhaps cause a fire. Replace fuses with the same rating every time.
Hyundai dealerships, hardware stores, and auto parts stores have replacement fuses.
Consult the fuse diagram on the fuse box cover or in your owner’s handbook. It will show the electrical component each fuse belongs.
Generally speaking, disconnecting the battery is not required when changing fuses. In case you’re handling delicate electrical parts, it could be a prudent precautionary measure.
Electrical shorts, overloaded circuits, or malfunctioning electrical parts can all result in blown fuses. To avoid problems in the future, it is imperative to look into the underlying reason.
With the right equipment and knowledge, an owner can change most fuses on their own. But it’s essential to get professional advice if electrical work makes you uneasy.
To avoid electric shocks, keep your hands away from metal surfaces and other electrical components when changing fuses. Prior to reaching the fuse box, make sure the car is off.
There can be a more serious electrical issue if changing the fuse doesn’t resolve the problem. For additional diagnostics, speak with a qualified mechanic or a Hyundai service center.
