Learn about Ford Fiesta (2011-2013) fuse box and relay’s locations, functions, and maintenance tips for optimal vehicle electrical system.
The Ford Fiesta is a popular subcompact car known for its efficiency and reliability, but like any vehicle, it depends on a well-protected electrical system to keep everything running smoothly. Fuses and relays are small but essential components that safeguard your Fiesta’s wiring from power surges and short circuits, preventing damage to critical systems like the lights, radio, and power windows.
If you’re dealing with a dead interior light, a non-working radio, or power windows that suddenly stopped responding, checking the fuse box is often the quickest way to diagnose the problem. Knowing exactly where your 2011–2013 Ford Fiesta’s fuse boxes are located and how to safely access them, can save you time and an unnecessary trip to the mechanic.
This guide walks through the fuse box and relay locations for the 2011–2013 Ford Fiesta, along with practical tips for safe access and fuse identification.

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 Fiesta?
The 2011–2013 Ford Fiesta uses two main fuse box locations: one under the hood and one inside the cabin. This straightforward two-box layout is typical of Ford’s compact car lineup and makes troubleshooting relatively simple once you know where to look.
1. Engine Compartment Fuse Box
The main engine bay fuse box is located near the back of the engine compartment, close to the battery on the driver’s side.
How to access it:
- Open the hood and locate the black plastic cover near the battery.
- Unclip the retaining tabs along the edges of the cover, most Fiesta models use simple snap-lock clips that don’t require tools.
- 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 it’s exposed to engine heat and road moisture, make sure the cover is properly reseated after inspection to prevent corrosion or water intrusion.
2. Interior Fuse Panel (Instrument Panel Fuse Box)
The cabin fuse box is located inside the car, typically on the driver’s side, tucked behind a small panel to the left of the steering wheel near the door.
How to access it:
- Turn the steering wheel fully to the left (if needed) for easier access to the panel.
- Locate the small access cover near the end of the dashboard, close to the door hinge.
- Gently pull the cover free, it’s usually secured with simple plastic clips that release with light pressure.
- Once removed, you’ll see the fuse layout along with a couple of small relays.
This panel handles interior circuits such as the radio, power windows, dashboard lights, wipers, and central locking system. It’s the fuse box you’ll likely need most often for everyday electrical troubleshooting.
How to Identify the Right Fuse or Relay
Both fuse boxes include a printed diagram, usually located on the inside of the cover or printed directly on a label near the fuse block, showing each fuse and relay’s number, amperage rating, and function.
When troubleshooting:
- Identify the malfunctioning component (e.g., “radio” or “rear wiper”) and match it to its corresponding number on the diagram.
- Confirm the amperage rating printed on the old fuse matches the replacement before installing a new one.
- For relays, use the diagram to confirm the correct slot, since several relays in the box may look identical despite controlling different systems.
If the printed diagram is missing or difficult to read, refer to your owner’s manual for a detailed fuse box diagram specific to your Fiesta’s trim level, as slight variations can exist between base models and higher trims with additional electrical features.
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 the fuse puller tool, often built into the fuse box cover, rather than metal tools like 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.
Checking and Replacing Fuses in Ford Fiesta
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
Passenger Compartment Fuse Panel:
The fuse panel is located behind the glove box. Open the glove box, press the sides inward and swing the glove box down.
Power Distribution Box:
The power distribution box is located in the engine compartment. It has high-current fuses that protect your vehicle’s main electrical systems from overloads.

Conclusion
Knowing the fuse box and relay locations on your 2011–2013 Ford Fiesta makes it much easier to handle minor electrical issues without unnecessary guesswork. With just two main fuse box locations; one under the hood and one inside the cabin, this compact car is relatively simple to troubleshoot once you’re familiar with the layout.
Always handle fuses and relays with care, confirm amperage ratings before replacing any component, and use the printed diagram 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 qualified mechanic or Ford dealership technician is the safest way to avoid further electrical complications.
