Learn about Ford Focus (EU) (AP/C307; 2007) fuse box and relay’s locations, functions, and maintenance tips for optimal vehicle electrical system.
The Ford Focus (AP/C307 platform) represents the facelifted second-generation Focus sold across Europe, offering refined styling and improved technology over its predecessor. As with any vehicle, this Focus generation depends on fuses and relays to protect its electrical system from power surges, short circuits, and wiring faults that could otherwise damage critical components.
If you’re experiencing problems like non-working headlights, a malfunctioning radio, or wipers that won’t respond, a blown fuse or faulty relay is often the root cause. Knowing exactly where your Focus’s fuse boxes are located and how to safely access them, can help you quickly diagnose and resolve many electrical issues without an unnecessary trip to the garage.
This guide covers the fuse box and relay locations for the 2007 Ford Focus (AP/C307), along with safe access methods and practical tips for identifying the correct fuse or relay.

WARNING
- Never replace a fuse with one that has a higher amperage rating.
- A fuse with a too-high amperage could damage the electrical part and cause a fire.
- On no account should fuses be repaired (e.g. patched up with tin foil or wire) as this may cause serious damage elsewhere in the electrical circuit or cause a fire.
- If a fuse blows repeatedly, do not keep replacing it. Instead, have the cause for the repeated short circuit or overload tracked and fixed.
- Terminal and harness assignments for individual connectors will vary depending on vehicle equipment level, model, and market.

Where Are the Fuse Boxes Located on the Ford Focus (AP/C307)?
The 2007 Ford Focus is equipped with two main fuse box locations: one in the engine compartment and one inside the cabin. This layout is consistent with most European Focus models from this era, making troubleshooting straightforward once you know where to look.
1. Engine Compartment Fuse Box
The primary fuse box is located in the engine bay, mounted near the battery, typically on the driver’s side or passenger’s side depending on right-hand-drive or left-hand-drive configuration.
How to access it:
- Open the bonnet and locate the black plastic cover near the battery.
- Unclip the retaining tabs along the edges of the cover, most versions use tool-free snap-lock clips.
- Lift the cover straight up to reveal the fuses and relays inside.
This fuse box protects higher-amperage components such as the headlights, engine cooling fan, horn, and starter relay. Since this area is exposed to engine heat and road moisture, ensure the cover is properly reseated after inspection to prevent corrosion.
2. Interior Fuse Panel (Passenger Compartment Fuse Box)
The cabin fuse box is located inside the vehicle, typically at the end of the dashboard on the driver’s side, near the door, or in some trims, tucked beneath the glovebox.
How to access it:
- If located near the dashboard edge, open the driver’s door and locate the small access panel near the door hinge area, then gently pull or unclip the cover.
- If located near the glovebox, open the glovebox fully and release the side stoppers to allow it to drop down further, revealing the fuse panel behind it.
- Once accessed, you’ll see the fuse layout along with several compact relays.
This panel controls interior circuits such as the radio, interior lighting, wipers, hazard warning lights, power windows, and central locking system.
3. Additional Relays Near the Battery
Beyond the main engine bay fuse box, certain standalone relays, such as the fuel pump relay, horn relay, or main relay, may be mounted separately near the battery or along the inner wing panel rather than housed within the primary fuse box.
How to access them:
- Inspect the area around the battery and inner wing panel for individually mounted relays plugged into the wiring harness.
- These relays can generally be pulled straight out of their socket for inspection or replacement.
Since these relays aren’t always grouped with the main fuse box, a wiring diagram specific to your Focus’s engine variant (petrol or diesel) is helpful for confirming exact locations.
How to Identify the Right Fuse or Relay
The fuse box covers typically include a printed diagram, either on the inside of the lid or on a label near the fuse block, listing each fuse and relay by number, amperage rating, and function.
When troubleshooting:
- Identify the malfunctioning component (e.g., “wipers” or “central locking”) and match it to its corresponding number on the diagram.
- Confirm the amperage rating on the old fuse matches the replacement before installing a new one.
- For relays, use a wiring diagram to confirm the correct location and function, since relays can look similar despite controlling different systems.
If the printed diagram is missing or difficult to read, refer to your owner’s manual or a verified fuse box diagram specific to your Focus’s model year and engine variant, as configurations can vary slightly between petrol and diesel versions, as well as between trim levels.
Safety Precautions Before Checking Fuses or Relays
- Turn off the ignition and remove the key before touching any fuse or relay.
- For more involved electrical work, disconnect the negative battery terminal to prevent accidental short circuits.
- Use a fuse puller tool or needle-nose pliers rather than metal screwdrivers, which can cause sparking.
- Never replace a fuse with one of a higher amperage rating than specified, as this can overload the circuit and create a fire hazard.
- If a replacement fuse blows immediately, stop and inspect the circuit for an underlying short rather than continuing to swap fuses.
- Given the age of this vehicle, inspect fuse box connectors and relay sockets for corrosion or wear, which can develop over time.
Checking and Replacing Fuses in Ford Focus
A fuse puller is located in the lid of the auxiliary fuse box.
Location of Fuse Boxes
Central Fuse Box:
This is located behind the glove compartment in the instrument panel.
To gain access to the fuse box:
- Remove the screws in the instrument panel trim underneath the glove compartment and let the trim panel drop down.
- Loosen the quick fix screws on the fuse box.
- Let the fuse box down and pull it towards you.
- Hang the fuse box in the front fixture of the bracket.
- Reinstall in the reverse order.
Auxiliary Fuse Box:
This is located on the left-hand side of the engine compartment. To open, pull up the lever at the rear of the fuse box and lift off the lid.

Conclusion
Knowing the fuse box and relay locations on your 2007 Ford Focus (AP/C307) makes it much easier to handle minor electrical issues without unnecessary guesswork. With two main fuse box locations; one under the bonnet and one inside the cabin, plus a few standalone relays near the battery, this Focus generation is relatively simple to troubleshoot once you’re familiar with its layout.
Always handle fuses and relays with care, confirm amperage ratings before replacing any component, and use the printed diagram or a wiring reference to correctly identify each fuse or relay. If an electrical issue persists after replacing a fuse, or if you’re unsure about diagnosing the problem yourself, consulting a mechanic experienced with European Ford Focus models is a smart next step.
