Introduction to Fusibles
Fusibles, commonly referred to as fuses, are small devices designed to protect electrical circuits from excessive current. When a circuit in your Ford Fusion 2012 draws more current than it can handle, the fuse will "blow," breaking the circuit and preventing damage to the wiring and components. This mechanism ensures the safety of your vehicle's electrical system and prevents potential fire hazards.
Fusibles come in various types, including blade fuses, cartridge fuses, and glass tube fuses. The Ford Fusion 2012 primarily uses blade fuses, which are color-coded and rated for specific amperages. Understanding the different types of fusibles and their ratings is essential for diagnosing and resolving electrical issues in your vehicle.
Fuse Box Location in Ford Fusion 2012
The Ford Fusion 2012 has two primary fuse boxes: the main fuse box and the auxiliary fuse box. The main fuse box is typically located under the dashboard on the driver's side, while the auxiliary fuse box is found in the engine compartment. Knowing the exact location of these fuse boxes is the first step in troubleshooting electrical problems.
Main Fuse Box
The main fuse box in the Ford Fusion 2012 houses fuses responsible for interior components such as the dashboard, infotainment system, and interior lighting. To access the main fuse box, you may need to remove a small panel under the dashboard. Refer to your vehicle's owner's manual for specific instructions.
Auxiliary Fuse Box
The auxiliary fuse box, located in the engine compartment, contains fuses for components like the engine control unit (ECU), cooling fans, and headlights. This fuse box is usually covered by a plastic lid labeled with a diagram of the fuses and their corresponding functions.
Understanding the Fuse Box Diagram
The fuse box diagram is an essential tool for identifying the purpose of each fuse in your Ford Fusion 2012. This diagram is typically printed on the inside of the fuse box cover or in the vehicle's owner's manual. It provides a detailed layout of the fuses, their amperage ratings, and the components they protect.

For example, a 15-amp fuse may protect the vehicle's interior lighting, while a 30-amp fuse could be responsible for the windshield wipers. Understanding the fuse box diagram will help you quickly locate and replace blown fuses, minimizing downtime and ensuring your vehicle remains operational.
Common Fuse Problems and Solutions
Blown fuses are one of the most common electrical issues in vehicles. Symptoms of a blown fuse include non-functional components, such as headlights, power windows, or the radio. If you suspect a blown fuse, follow these steps:
- Locate the fuse box and identify the affected circuit using the fuse box diagram.
- Inspect the fuse visually for a broken filament or discoloration.
- Replace the blown fuse with a new one of the same amperage rating.
Repeatedly blown fuses may indicate an underlying electrical issue, such as a short circuit or overloaded circuit. In such cases, it is advisable to consult a professional mechanic to diagnose and resolve the problem.
How to Replace Fusibles in Ford Fusion 2012
Replacing fusibles in your Ford Fusion 2012 is a straightforward process that can be completed in a few simple steps:
- Turn off the vehicle and ensure the ignition is in the "off" position.
- Locate the fuse box and remove the cover to access the fuses.
- Use a fuse puller tool to remove the blown fuse carefully.
- Insert a new fuse of the same amperage rating into the slot.
- Replace the fuse box cover and test the affected component to ensure it is functioning correctly.
Tools and Materials Needed for Fuse Replacement
To replace fusibles in your Ford Fusion 2012, you will need the following tools and materials:
- Fuse puller tool (usually included in the vehicle's toolkit)
- Spare fuses of various amperage ratings
- Vehicle owner's manual for reference
- Flashlight (optional, for better visibility)
Safety Tips When Working with Fusibles
