2021 Kia Sedona Fuses and Fuse Box | Check if a Fuse has Blown

Of course! To ensure correct maintenance and comprehend the Kia Sedona 2021’s electrical system, it is essential to familiarize yourself with the fuses and fuse box. Fuses are components of the electrical system that provide protection. In the event of a power surge or short circuit, they are made to break the circuit and shield the components from harm. Every fuse has a designated amperage and safeguards a specific electrical system or component. Usually found under the dashboard, in the glove compartment, or on the driver’s side panel, the fuse box of the Kia Sedona 2021 is easily accessible and handy to locate. You can find the precise location of the fuse box cover using the owner’s manual or a labeled diagram.

There are different kinds of fuses in the fuse box, and each kind is intended for a particular circuit. The amperage ratings of these fuses vary according to the electrical load they are protecting, and they can be either blade-type or cartridge fuses. In order to avoid electrical problems or component damage, it is imperative to replace a blown fuse with one of the same amperage rating. It is advised to regularly check the fuses in your car, particularly when diagnosing electrical issues. A blown fuse may be indicated if a component stops working, such as the radio, power windows, or lights. To check and replace a blown fuse, locate the defective fuse, remove it with fuse pullers (which are typically included in the fuse box), and replace it with a new fuse that has the appropriate rating.

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 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 melt.
If the electrical system does not work, first check the driver’s side fuse panel.
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 Kia dealer.
Three kinds of fuses are used: blade type for lower amperage rating, cartridge type, and multi fuse for higher amperage ratings.

WARNING
Fuse replacement

• Never replace a fuse with any-thing but another fuse of the same rating.
• A higher capacity fuse could cause damage and possibly a fire.
• Never install a wire or aluminum foil instead of the proper fuse – even as a temporary repair. It may cause extensive wiring damage and a possible fire.
• Do not arbitrarily modify or add-on the electric wiring of the vehicle.

CAUTION
Do not use a screwdriver or any other metal object to remove fuses because it may cause a short circuit and damage the system.

NOTICE

• When replacing a fuse, turn the ignition “OFF” and turn off the switches of all electrical devices then remove the battery (-) terminal.
• The actual fuse/relay panel label may differ from the equipped items.

WARNING
Electrical Fire
Always ensure replacement fuses and relays are securely fastened when installed. Failure to do so can result in a vehicle fire.

CAUTION

• When replacing a blown fuse or relay, make sure the new fuse or relay fits tightly into the clips. Failure to tightly install the fuse or relay may cause damage to the wiring and electric systems.
• Do not remove fuses, relays and terminals fastened with bolts or nuts. The fuses, relays and terminals may not be fastened correctly which may cause vehicle damage.

CAUTION

• Do not input any other objects except fuses or relays into fuse/relay terminals such as a screwdriver or wiring. It may cause contact failure and system malfunction.
  Do not plug in screwdrivers or aftermarket wiring into the terminal originally designed for fuse and relays only. The electrical system and wiring of the vehicle interior may be damaged or burned due to contact failure.
• If you directly connect the wire on the taillight or replace the bulb which is over the regulated capacity to install trailers etc., the inner junction block can get burned.

CAUTION
Visually inspect the battery cap to ensure it is securely closed. If the battery cap is not securely closed, moisture may enter the system and damage the electrical components.

WARNING
Electrical wiring repairs
All electrical repairs should be performed by authorized Kia dealerships using approved Kia parts. Using other wiring components, especially when retrofitting the audio system or theft alarm system, or remote engine control may cause vehicle damage and increase the risk of a vehicle fire.

NOTICE
Remodeling Prohibited
Do not rewire your vehicle in any way as doing so may affect the performance of several safety features in your vehicle. Rewiring your vehicle may also void your warranty and cause you to be responsible for any subsequent vehicle damage which may result.

NOTICE
Window tinting pre-caution
Window tint (especially metallic film) might cause communication errors or poor radio reception, and malfunctioning automatic lighting system due to reflections from the mirror tint inside the vehicle. The solution used might also leak into the electronic components, causing malfunctions or damage.

Inner panel fuse replacement

1. Turn the ignition switch and all other switches off.
    
2. Open the fuse panel cover.
   
3. Pull the suspected fuse straight out. Use the removal tool provided on the  engine compartment fuse panel cover.
    
    
4. Check the removed fuse; replace it if it is blown.
   Spare fuses are provided in the engine compartment fuse panel.
    
5. 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 Kia dealer.

If you do not have a spare, use a fuse of the same rating from a circuit you may not need for operating the vehicle, such as the power outlet fuse.
If the head lamp, turn signal lamp, stop signal lamp, fog lamp, DRL, tail lamp, HMSL do not work and the fuses are not blown, check the fuse panel in the engine compartment. If a fuse is blown, it must be replaced.

NOTICE
If the headlamp, fog lamp, turn signal lamp, or tail lamp malfunctions even without any problem to the lamps, have the vehicle checked by an authorized Kia dealer for assistance.

Fuse switch

Always set the fuse switch to the ON position before using the vehicle.
If you move the switch to the OFF position, some items such as audio and digital clock must be reset and the transmitter (or smart key) may not work properly. When the switch is Off, the caution will be displayed on the instrument cluster.
Always place the fuse switch in the ON position while driving the vehicle. If the switch is located in the “OFF” position, a caution indicator will be displayed in the cluster.

CAUTION
Fuse Panel Covers
The contact points of the switches may wear out with excessive use. Please refrain from excessive use of the switches (except for long-term parking for over 1 month).

NOTICE

• Set all switches to ON before driving.
   
• If the vehicle is going to be unused for over 1 month, set all switches to OFF to prevent the batteries from draining.

Engine compartment fuse replacement
