The 2012–2014 Ford Focus uses fuses and relays to protect its electrical system from overloads, short circuits, and other faults. Fuses are designed to break the circuit when too much current flows, while relays act like switches for higher-power systems such as lighting, cooling fans, and starter circuits.
If a light stops working, the radio goes dead, or a power accessory suddenly fails, the first thing many owners should check is the fuse box location. Knowing where the fuse boxes and relays are on your Ford Focus (US) (2012–2014) makes troubleshooting much easier and can save time, money, and stress.
This guide explains the main fuse box and relay locations on this model, how to access them, and how to use the relay diagram and fuse chart to identify the right part.
Ford Focus (US) (2012–2014) Fuse Box Locations
How to Identify Fuses and Relays
Each fuse box cover should include a printed fuse chart or relay diagram. If the cover does not have one, check the owner’s manual. The diagram shows the fuse number, amperage rating, and the system it protects.
When troubleshooting:
- Match the broken feature to the correct label on the fuse chart.
- Check the fuse number before removing anything.
- Replace only with the same amperage rating.
- Use the relay diagram to make sure you remove the correct relay slot.
If a fuse looks fine but the problem continues, the relay or another part of the circuit may be the issue. In some cases, the fault may be in wiring or a control module rather than the fuse itself.
Safety Precautions Before Checking Fuses or Relays
Before working on any fuse box location, take a few basic safety steps:
- Turn off the ignition.
- Remove the key or keep the key fob away from the vehicle.
- If you plan to do more than a quick visual check, disconnect the negative battery terminal.
- Use a fuse puller or plastic tool when possible.
- Never replace a fuse with one of a higher amperage rating.
- If a replacement fuse blows again right away, stop and look for the underlying electrical fault.
These precautions help protect both you and the vehicle’s electrical system.

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.

Checking and Replacing Fuses in Ford Focus (US)
If electrical components in the vehicle are not working, a fuse may have blown. Blown fuses are identified by a broken wire within the fuse. Check the appropriate fuses before replacing any electrical components.
Location of Fuse Boxes
1. Engine Compartment Fuse Box
The main fuse box location on the Ford Focus (US) (2012–2014) is in the engine compartment. This box is often called the power distribution box and is usually found near the battery and inner fender area under the hood.
How to access it:
- Open the hood and locate the black plastic fuse box cover in the engine bay.
- Release the retaining clips or tabs on the cover.
- Lift the cover off carefully to expose the fuses and relays inside.
This engine bay fuse box handles many of the larger electrical circuits in the car. It commonly protects systems such as the headlights, cooling fan, horn, starter circuit, and other high-current components. Because it is exposed to heat and moisture, always make sure the cover is snapped back into place after inspection.
2. Passenger Compartment Fuse Panel
The second major fuse box location is inside the cabin, behind the glove box on the passenger side of the dashboard. On this model, the interior fuse panel is not usually in the trunk. Instead, it is tucked away behind the glove compartment area for easier access from inside the car.
How to access it:
- Open the glove box.
- Release the side stops or tabs that keep the glove box from opening fully.
- Lower the glove box carefully until you can see the fuse panel behind it.
- Remove any small cover or trim piece if needed to reach the fuse block.
This fuse panel protects many interior systems, including the radio, SYNC infotainment system, power windows, interior lighting, accessory outlets, wipers, and central locking. If a cabin feature stops working, this is usually the first place to check.
Relay Locations on the Ford Focus (US) (2012–2014)
On this Ford Focus, most relays are built into the two main fuse boxes rather than being spread across several separate relay boxes. That means the relay diagram printed on the fuse box cover or in the owner’s manual is very important.
The engine compartment box typically contains relays for higher-load systems such as the cooling fan, horn, and starter-related circuits. The cabin fuse panel may also contain smaller relays for interior and convenience features.
If your car has aftermarket accessories, such as added lights or audio equipment, those may have their own inline relays or fuse holders installed by a previous owner. These are not factory relay boxes, so they may be located in different places depending on the installation.
Power Distribution Box:
The power distribution box is located in the engine compartment. The power distribution box contains high-current fuses that protect your vehicle’s main electrical systems from overloads.
Luggage Compartment Fuse Panel:
The fuse panel is located in the luggage compartment behind the left side wheel well. Remove the fuse panel cover to gain access to the fuses.

Conclusion
Understanding the fuse box and relay locations on the Ford Focus (US) (2012–2014) makes basic maintenance and troubleshooting much simpler. With one fuse box in the engine compartment and one inside the cabin behind the glove box, this model has a fairly straightforward layout once you know where to look.
Always use the correct relay diagram and fuse chart, handle parts carefully, and replace blown fuses with the proper amperage only. If the same fuse keeps failing or the electrical issue does not go away, it is a good idea to have the car checked by a qualified technician.
