2021-2022 Hyundai Santa Fe Fuse Box Diagrams, relays, wiring, location, rating, assignment, rating and replacement.
Fuses and Relay
- Any vehicle’s electrical system usually is protected by fuses.
- This car has 5 fuse panels, one located in the driver’s side panel bolster, the others are in the engine compartment.
- If any of your vehicle’s lights, accessories, or controls do not function, 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 ratings.
- If the replacement fuse blows, this indicates an electrical problem.
- Avoid using the system involved. We recommend that you immediately consult an authorized HYUNDAI dealer.
- Always replace a fuse with 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.
- Do not use a screwdriver or any other metal object to remove fuses because it may cause a short circuit and damage the system.
- In case of 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 undamaged, check the fuse panel in the engine compartment. If a fuse is blown, it must be replaced with the same rating.
- 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. - Not all fuse panel descriptions in this manual may be applicable to your vehicle; the information is accurate at the time of printing. When you inspect the fuse box on your vehicle, refer to the fuse box label and consult the owner’s manual.
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 (Fuse Puller) provided in the engine compartment fuses 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, consults an authorized HYUNDAI dealer.
Engine compartment panel fuse replacement
Blade fuse / Cartridge fuse
- Turn the vehicle off.
