Fixing a Blown Fuse: 2016 Hyundai Azera Relay and Fuse Diagrams

Fixing a Blown Fuse: 2016 Hyundai Azera Relay and Fuse Diagrams

It’s pretty easy to fix a blown fuse in a 2016 Hyundai Azera. This can save you time and money compared to going to the store or a mechanic. Fuse boxes are very important for keeping different electrical parts of your car safe from damage caused by electrical shocks or short circuits. When a fuse blows, it cuts off the electricity that it’s supposed to protect, which stops the part from working. To fix this problem, you’ll need to find your Azera’s switch box. It’s usually under the dashboard or in the engine bay. Finding the fuse diagram, which is usually on the fuse box cover or in the owner’s guidebook, will help you figure out which fuse is bad and which part isn’t working. Once you know where the blown fuse is, carefully remove it with fuse pullers or needle-nose pliers and put in a new fuse with the same current rating. It is very important to use the right amperage fuse so that you don’t damage the circuit or put people in danger. After changing the fuse, make sure the part is working right by testing it before closing the fuse box. With this easy fix, you can get your Hyundai Azera’s electrical systems working again without having to call a professional.

FUSES

A vehicle’s electrical system is protected from electrical overload damage by fuses. This vehicle has 2 fuse panels, one located in the driver’s side panel bolster, and another 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. If the electrical system does not work, first check the driver’s side fuse panel. Before replacing a blown fuse, 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. Three kinds of fuses are used: blade type for lower amperage rating, cartridge type, and multi-fuse type for higher amperage rating.

WARNING – Fuse replacement

• Never replace a fuse with anything 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.

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

CAUTION

• When replacing a blown fuse or relay with a new one, make sure the new fuse or relay fits tightly into the clips The incomplete fastening fuse or relay may cause the vehicle wiring and electric systems damage and a possible fire.
• Do not remove fuses, relays, and terminals fastened with bolts or nuts. The fuses, relays, and terminals may be fastened incompletely, and it may cause a possible fire. If fuses, relays, and terminals fastened with bolts or nuts are blown, consult an authorized HYUNDAI dealer.
• Do not input any other objects except fuses or relays into fuse/relay terminals such as a driver or wiring. It may cause contact failure and system malfunction.

Instrument 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 in the engine compartment fuse panel.
4. Check the removed fuse; replace it if it is blown.
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 HYUNDAI 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 headlights 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.

Fuse switch
Always, put the fuse switch at the ON position. A notice will appear on the LCD to notify the driver the fuse switch should be in the ON position. For more details, refer to “LCD” in section 4. If you move the switch to the OFF position, some items such as the audio and digital clock must be reset, and or the smart key may not work properly.

CAUTION

• Always place the fuse switch in the ON position while driving the vehicle.
• Do not operate the fuse switch repeatedly. The switch may be worn out.

Engine compartment fuse replacement

1. Turn the ignition switch and all other switches off.
2. Remove the fuse panel cover by pressing the tab and pulling it up.
3. 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.
4. 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 – Fuse panel covers
After checking the fuse panel in the engine compartment, securely install the fuse panel cover to prevent electrical failures that may occur from water contact.

Main fuse
If the main fuse is blown, it must be removed as follows:

1. Turn off the engine.
2. Disconnect the negative battery cable.
3. Remove the nuts shown in the picture above.
4. Replace the fuse with a new one of the same rating.
5. Reinstall in the reverse order of removal.

Multi fuse
If the multi fuse is blown, it must be removed as follows:

1. Turn off the engine.
2. Disconnect the negative battery cable.
3. Remove the fuse panel in the engine compartment.
4. Remove the nuts shown in the picture above.
5. Replace the fuse with a new one of the same rating.
6. Reinstall in the reverse order of removal.

If the multi fuse is blown, consult an authorized HYUNDAI dealer.

How to Replace Fuses of Hyundai Azera

Replacing fuses in a Hyundai Azera is a relatively straightforward process.

Here’s a detailed guide along with some tips:

1. Locate the Fuse Box: The fuse box in the Hyundai Azera is usually located inside the cabin, often beneath the dashboard on the driver’s side. In some models, there might be an additional fuse box in the engine bay. 

2. Turn Off the Vehicle: Before replacing any fuses, ensure that the vehicle’s ignition is turned off, and the key is removed from the ignition switch to prevent any electrical mishaps.

3. Identify the Blown Fuse: Use a flashlight to inspect the fuses inside the fuse box. Look for any fuses with a broken wire or a discolored appearance, which indicates that they have blown. 

4. Select a Replacement Fuse: Check the amperage rating printed on the blown fuse and select a replacement fuse with the exact same amperage rating. Using a fuse with a different amperage rating could cause electrical issues or damage to your vehicle.

5. Remove the Blown Fuse: Once you’ve identified the blown fuse and selected a replacement, use a fuse puller tool or a pair of needle-nose pliers to grip the blown fuse firmly. Pull the fuse straight out of its socket, being careful not to damage the fuse box or adjacent fuses in the process.

6. Insert the Replacement Fuse: Take the replacement fuse and insert it into the empty socket in the fuse box. Make sure the fuse is seated securely and fully inserted into the socket to ensure proper electrical connection.

7. Check for Proper Fit: Double-check that the replacement fuse fits snugly into the socket and is of the correct amperage rating. It should not be loose or protruding from the socket.

8. Replace the Fuse Box Cover: Once you’ve replaced the blown fuse with a new one, carefully replace the fuse box cover and ensure that it is securely fastened. This helps to prevent water or debris from entering the fuse box.

9. Test the Circuit: Turn the ignition key to the accessory position or start the vehicle to test the circuit associated with the replaced fuse. Verify that the electrical component or system is functioning properly.

10. Dispose of the Blown Fuse: Dispose of the blown fuse properly. You can keep it as a spare in case of future emergencies or dispose of it according to local regulations for electronic waste.

Tips:

• Use the Fuse Puller Tool: If your Hyundai Azera comes with a fuse puller tool, use it to remove the blown fuse. This can help prevent damage to the fuse or the fuse box.
• Check Other Fuses: If you find one blown fuse, it’s a good idea to check the surrounding fuses as well. Sometimes, multiple fuses may blow simultaneously due to the same issue.
• Keep Spare Fuses: It’s wise to keep a set of spare fuses of various amperage ratings in your vehicle’s glove compartment for quick replacement in case of emergencies.
