This automotive maintenance tutorial was specifically written to assist owners of the 6th generation (2017, 2018, 2019, 2020 and perhaps also the 2021 model year) Hyundai Elantra sedan in checking or changing a blown electrical fuse or a faulty relay in either the engine bay or the interior passenger compartment electrical panels.

Owners of other Hyundai, Genesis or Kia vehicles such as the Sonata, Accent, Veloster, Ioniq, Kona, Nexo, Venue, Tucson, Santa Fe, Palisade, G70, G80, G90, Soul, Sportage, Niro, Sorento, Telluride, Rio, Forte, Optima, Stinger, Cadenza, K900, Sedona and Seltos may also find these DIY instructions to be helpful.

This 2018 Elantra is equipped with the newest style of Micro2 Fuses and Micro Cartridge Fuses which can be purchased in assortments online at Amazon.

(Please check the type of old fuses installed in your Elantra before you buy new fuses.)

A white plastic fuse puller tool should be included on the engine bay electrical block. If the tool is missing, you could also use a pair of needle nose pliers with rubber insulated handles.

The first two steps are to open the hood and then move to the right (driver) side of the engine bay.

The primary electrical panel compartment is on the right of the engine bay just to the right of the 12V automotive battery and behind the driver side headlight housing.

Pull Out Access Cover
There is a white plastic fuse puller tool located at the front left corner of the electrical panel.

Pull the tool straight out of its socket.

If the tool is missing, you could also use a pair of needle nose pliers with rubber insulated handles.

The interior passenger compartment electrical panel is located behind a plastic access cover on the bottom left side of the dashboard.

The cover is situated close to where the driver's left knee would reside while driving. The cover has the words "FUSE / OBD" printed on it.

Insert your fingers into the opening in the bottom of the cover and gently pull it out.

Hold Up Fuse To Light
Pinch the end of the tool to open the jaws.

Place the jaws over the old fuse that you would like to check or change.

Pull the old fuse straight out of the socket.

To check the condition of the old fuse, hold it up to a light bulb.

If the thin metal strip or band in the translucent plastic center of the old fuse appears to be burnt or broken, the old fuse is most likely "blown" and should be replaced.

If the thin metal bar in the middle of the old fuse appears to be intact, it should still be in good working condition. Since new fuses are so inexpensive, you should still replace the fuse as part of your electrical problem troubleshooting process.

Replace Fuse Puller Tool
Please check the type of old fuses in your Elantra before purchasing new fuses. The older models might be equipped with standard mini blade fuses or the "low profile" fuses.

This 2018 Elantra is equipped with Micro2 Fuses and Micro Cartridge Fuses.

Push a new fuse of the same amperage rating (e.g. 5A, 10A, 15A, 20 amps, etc.) straight into the socket.

If you would like to add a hard-wired 12V power source for an automotive accessory such as a digital gauge, cell phone charger, dash cam, back-up camera, radar detector or an LED lighted Uber / Lyft sign, install an "Add-A-Circuit" fuse tap adapter (also known as a piggy back fuse holder).

Use a digital multimeter to find either a "switched" or "hot / live" circuit depending on your needs. A "switched" circuit will be off when the ignition is in the "Off" position and only supply 12 volt power when the ignition is in the "On" position. A constant or "hot" / live circuit will always supply 12V power even when the car's ignition is switched off. Be careful to not drain the 12V car battery if you choose a hot / live circuit that is always on.

If you suspect that a faulty relay is the cause of your problem, the easiest way to check is to simply replace the relay with a new one of the same amperage rating.

You could also test the old relay with a digital multimeter tool.

Push the white plastic fuse puller tool back into its socket on the front left corner of the engine bay electrical panel.

Re-Insert Access Cover

Pop Cover In Place
Lower the cover over the engine bay fuse box.

Push on the cover to secure the two retaining clips.

You should feel or hear the two retaining "click" securely into place.

Replace the access cover for the interior passenger compartment electrical panel by first inserting the tabs on the top edge and then pop in the bottom edge.

Make sure the cover is flush with the rest of the dashboard.

Test the electrical component that you were having issues with such as the stereo, horn, headlights, tail lights, power driver seat, A/C system, power windows, interior lights, tail lights, power door locks, etc.

If you are still having the same electrical problem, there may be a shorted out wire or the component itself needs to be replaced.

Be sure to write down the fuse change in your vehicle's service records.
