Open the main power compartment under the hood on the driver’s side to inspect circuits controlling the engine, headlights, and cooling fans. Verify each slot using the printed layout on the cover before removing any components to avoid misplacement.
The secondary panel is behind the glove compartment and manages circuits for interior accessories such as the audio system, climate controls, and power windows. Refer to the label inside the cover to match each slot with the correct amperage and function.
Check terminals for corrosion or looseness before reinstalling any element. Dirty or oxidized contacts can interrupt current flow even if the component itself is intact, causing intermittent failures.
Test each circuit with a multimeter to confirm continuity. Identifying the exact element that has failed prevents unnecessary replacements and ensures the stability of the electrical system.
Organize replacement units by amperage rating and label removed components. Reinstall each element in its original location to maintain proper circuit protection and prevent damage to sensitive systems.
Electrical Panel Guide for Your Sedan

Access the primary power compartment under the hood on the driver’s side to inspect circuits controlling the engine, headlights, and cooling fans. Use the printed layout on the cover to identify each slot before handling components.
The secondary panel behind the glove compartment manages interior electronics such as the audio system, climate controls, and power windows. Slide the glove compartment fully open to reach the cover and read the labels to match each slot with its designated system.
Check terminals for corrosion or loose connections before reinstalling any elements. Even fully functional components will fail to supply current if contacts are dirty or oxidized, causing intermittent electrical issues.
Test each circuit with a multimeter to confirm continuity and voltage levels. Identifying the exact element that has failed avoids unnecessary replacements and ensures reliable operation of all vehicle systems.
Keep replacement units organized by amperage rating and label removed components before reinstalling. Returning each element to its original location maintains proper circuit protection and prevents overcurrent damage to sensitive electronics.
Locating the Main and Auxiliary Panels in the Vehicle

Open the primary electrical compartment under the hood on the driver’s side near the battery to access circuits controlling the engine, headlights, and cooling systems. Use the printed label inside the cover to identify each slot before removing any components.
The secondary interior panel is behind the glove compartment and handles circuits for:
- Audio system
- Climate control
- Power windows and door locks
- Interior lighting
Slide the glove compartment fully open to reach the cover and ensure visibility of the circuit labels. Some slots may be recessed, so using a flashlight can help accurately identify each element.
Inspect terminals for corrosion or looseness before reinstalling components. Dirty or oxidized contacts can interrupt current flow, even if the protective element itself is intact.
High-draw systems such as heated seats or the rear defroster may be connected to both panels. Check continuity in each corresponding slot to confirm which panel is supplying power to the system.
- Label removed elements with tape or a marker.
- Match amperage ratings when reinstalling components.
- Test all systems after replacement, including headlights, HVAC, and audio.
- Verify that both panels deliver stable current to all circuits.
