Partly covered: Ford UK lists two Focus (2015) handbooks for 2015 whose build dates overlap but whose fuse charts differ, and doesn’t say which applies to cars built in the overlap. Both are shown below — where they differ, compare the legend in your fuse box before removing anything.
Where is the fuse box?
Option A Focus (2010)
Option B Focus Electric (2013) or Focus Electric (2015)
Pre-fuse box
In the electric motor compartment, on the front of the 12 volt battery box
- Ford says these are high current fuses: if one needs replacing, have it done by an authorised dealer.
Option C Focus (2015) · Built up to 15 February 2015 or Focus (2015) · Built from 16 February 2015
Engine compartment fuse box

How to replace the fuse safely
- Switch off the ignition and all electrical equipment. Take the key out, or move a keyless fob away from the car.
- Open the fuse box and find the fuse using the number on the cover legend or the chart on this page.
- Pull the fuse straight out with the plastic fuse puller (usually clipped inside the fuse box) or fine-nose pliers.
- Look at the metal strip inside the fuse. A broken or burnt strip means it has blown.
- Fit a new fuse with exactly the same amperage rating. The number on top and the colour should match.
- Refit the cover, switch on and test the component.
- Never fit a fuse with a higher amperage rating than specified. It can let wiring overheat.
- Never bridge a fuse with wire, foil or anything else.
Checking the relay
- With the ignition off, pull the relay straight out of its socket. Rock it gently if it is tight.
- Relays rarely look damaged when they fail. To test, swap in an identical relay with the same part number from a non-essential circuit.
- If the fault moves to the other circuit, replace the relay. If it doesn’t, the problem is elsewhere.
Fuse keeps blowing?
A fuse that blows again straight away is doing its job. Something on that circuit is drawing too much current. Common causes are damaged wiring shorting to the bodywork, a failing motor or socket, water getting in, or a faulty accessory. Fitting fuse after fuse, or a bigger fuse, won’t fix the fault and can overheat the wiring. Have the circuit tested by an auto electrician.
Not the fuse? Check these next.
Stop if it overheats
If the temperature gauge climbs or a warning light comes on, stop safely and switch off. Never open the coolant cap on a hot engine.
Coolant level
Check the coolant level with the engine cold. Low coolant causes overheating more often than a fan fault.
Silent fan on a cold engine
The fan normally runs only when the engine is hot or the air conditioning is on, so a silent fan on a cold engine is normal.
