FUSES
- A: Blade type,
- B: Cartridge type,
- C: Multi type,
- D: Midi type
- O: Normal,
- X: Blown
A vehicle’s electrical system is protected from electrical overload damage by fuses. This vehicle has 5 fuse panels, one located in the driver’s side panel bolster, and the other in the engine compartment.
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 retailer of Genesis Branded products.
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
A: Driver’s side, B: Trunk
- 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 1 provided in the engine compartment fuse panel cover.- 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 retailer of Genesis Branded products.
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 headlights or other electrical components do not work and the fuses are undamaged, check the fuse panel in the engine compartment. If a fuse is blown, it must be replaced with the same rating.
Engine Compartment Panel Fuse Replacement
Blade fuse/Cartridge fuse
A: Blade type fuse, B: Cartridge type fuse
- 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 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 retailer of Genesis Branded products.
NOTICE
After checking the fuse panel in the engine compartment, securely install the fuse panel cover. You may hear a clicking sound if the cover is securely latched. If it is not securely latched, electrical failure may occur from water contact.
Multi fuse/Midi fuse
A: Multi type fuse, B: Midi-type fuse
If the multi fuse or midi fuse is blown, consult an authorized retailer of Genesis Branded products.

How to Replace Fuses Genesis G90
Replacing fuses in a Genesis G90 is a relatively straightforward process. Here’s a detailed guide along with some helpful tips:
-
Locate the Fuse Box: The fuse box in the Genesis G90 is typically situated either under the dashboard on the driver’s side or under the hood near the battery. Look for a rectangular or square-shaped black plastic box.
-
Identify the Fuse Box Cover: The fuse box cover may have a diagram indicating which fuses correspond to various components.
-
Turn Off the Vehicle: Before beginning any work on the fuses, ensure that the vehicle is completely turned off, and the key is removed from the ignition.
-
Open the Fuse Box Cover: Depending on the model year of your Genesis G90, you may need to press a release latch or simply lift the cover to access the fuses. Some models may have additional covers within the fuse box itself.
-
Determine the Faulty Fuse: If you’re encountering a specific electrical issue, utilize the fuse diagram to identify which fuse corresponds to the malfunctioning component.
-
Remove the Fuse: Use a fuse puller tool if one is available, or carefully grip the fuse with your fingers and pull it straight out. Ensure you do this gently to avoid damaging the fuse or the fuse box.
-
Inspect the Fuse: Visually inspect the fuse to determine if the wire inside is intact. If the wire is broken or there are signs of damage, the fuse requires replacement.
-
Select the Correct Replacement Fuse: Using an incorrect fuse can lead to electrical problems or damage to your vehicle.
-
Insert the New Fuse: Carefully insert the new fuse into the slot from which you removed the old one. Ensure that it fits securely and is seated properly.
-
Close the Fuse Box Cover: After replacing the fuse, firmly close the fuse box cover to prevent any dust or moisture from entering the fuse box.
-
Test the Component: Turn the ignition to the accessory position (without starting the engine) and test the component associated with the fuse to verify that it’s functioning correctly.
Tips:
- Keep a variety of spare fuses in your vehicle, covering different amperages, in case of emergencies.
- Periodically inspect your fuses if you notice any electrical issues with your Genesis G90.
- Handle fuses delicately to prevent damage to the fuse box or other components.
- If you’re uncertain about which fuse controls a particular component, consider seeking assistance from a professional mechanic.
FAQs
A fuse is a type of safety device used to guard against overcurrent in electrical circuits. It is made composed of a metal strip or wire that melts when it comes into contact with too much current, cutting off the circuit.
The fuse box may be located in the engine compartment, under the dashboard, or in the trunk, though its exact location varies.
The location of the fuse box determines the procedure for accessing i. To access the fuses, you will typically need to remove a cover or panel.
Usually, all you need is a fuse puller or a set of needle-nose pliers, which are either included in the fuse box or may be bought separately.
A wire that has melted or broken clearly indicates a blown fuse. Additionally, some fuse boxes include a schematic that shows what each fuse is used for.
The car might use cartridge fuses or blade fuses, among other types of fuses. See the owner’s handbook for more information on particulars.
No, a fuse with the same amp rating must always be used to replace a blown one. A larger amp fuse may cause damage or other electrical problems.
Usually, a visual examination suffices. The fuse is probably still working if the metal strip inside of it is still in place.
Electrical errors, short circuits, and overloading a circuit with too many devices can all lead to blown fuses.
An underlying electrical problem could be the cause of a fuse that keeps blowing. Seek advice from a qualified mechanic to identify and resolve the issue.
Circuit breakers and fuses have comparable functions, but they are not always interchangeable. Follow the fuse kinds that are suggested for your car.
Yes, different electrical components are protected by separate fuses. To find the fuse that fits a particular function, consult the fuse box diagram.
Even while fuses usually don’t break easily, it’s a good idea to check them if you have any electrical problems. It’s also a good idea to do routine checks when doing regular maintenance.
Depending on how the blown fuse operates. If it’s not a necessary part, you might be able to drive for a short while. To prevent future problems, it is advisable to replace the fuse as soon as possible.
