Start by locating the primary electrical panel beneath the dashboard on the driver’s side. This area controls crucial vehicle functions like interior lights, dashboard systems, and power windows. Accessing it is easy; just remove the cover to reveal the individual circuits.
Next, check the secondary compartment located under the hood. This panel manages power to components like the alternator, battery, and engine-related systems. It’s often situated near the driver’s side of the engine bay for quick access.
Each section of the compartments is clearly labeled to indicate the systems they control. Pay attention to these labels to identify which fuse corresponds to specific features. For example, one section will manage lighting, while another could be dedicated to more complex systems like the air conditioning or safety features.

If an electrical component stops working, use the manual to match the malfunctioning part with its corresponding fuse. Replacing a blown fuse with one of the same amperage rating will help restore functionality. Avoid using a fuse with a higher rating, as it could cause further damage to the system.
Regularly inspect both compartments for corrosion or wear, as these can affect the performance of the electrical systems. Keeping a set of replacement fuses handy will ensure quick fixes when issues arise.

Begin by locating the primary electrical compartment beneath the dashboard, typically on the driver’s side. This area controls the car’s interior systems such as lights, wipers, and various dashboard features. The panel is easily accessible by removing the cover without requiring special tools.
Additionally, there is a secondary compartment located under the hood. This area regulates engine-related systems, including the alternator, cooling fans, and battery. It’s generally positioned near the driver’s side of the engine bay, offering quick access for maintenance.
The compartments are organized in sections, with each section dedicated to specific systems in the vehicle. For instance, one section is for lighting and power accessories, while another may manage safety systems or climate control. The labeling on the panel makes identifying the function of each section straightforward.
If you notice a malfunction in a particular system, check the manual for the layout of each section. The labels beside the electrical components make it easy to pinpoint which fuse controls the malfunctioning feature. Always replace a faulty component with a fuse of the correct amperage rating to prevent further damage.
It’s also important to inspect both compartments regularly for any signs of corrosion or wear. Over time, corrosion can affect the performance of the connections and cause issues with the vehicle’s electrical systems. If corrosion is detected, it’s best to clean the connections before replacing any blown fuses.
- Primary panel – Controls the interior systems, like lights and dashboard electronics.
- Secondary panel – Regulates engine-related functions such as the alternator and cooling fans.
- Relay compartments – Often included to manage high-power features like windshield wipers and air conditioning systems.
Having spare fuses on hand is a good practice. Always carry replacements of various amperage ratings to ensure that you can quickly replace any blown components, restoring full functionality to the vehicle’s electrical systems.
Locating the Main and Secondary Fuse Panels in 2022 Sonata

Start by locating the primary electrical compartment on the driver’s side, under the dashboard. This compartment is crucial for controlling the vehicle’s interior systems, including lights, air conditioning, and safety features. Simply remove the cover panel to access the fuses inside.
The secondary panel can be found under the hood, near the engine bay. This compartment is responsible for managing engine-related components such as the alternator, cooling fans, and battery connections. It is located on the driver’s side for easier access during maintenance.
Both panels are clearly marked with labels indicating which sections control which systems. By referring to these labels, you can quickly identify the appropriate circuit in case of a malfunction. Make sure to check both compartments to ensure all systems are functioning correctly.

If you’re unsure about which panel controls a specific feature, consult the vehicle’s manual for a detailed guide. The layout is straightforward and should help you locate the necessary components without difficulty.
For ongoing maintenance, check both compartments periodically for signs of corrosion or wear. Cleaning the contacts can prevent future electrical issues and help maintain optimal vehicle performance over time.
