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.

Which 2015 Focus do you have?

The starter fuse & relay differs between versions of the 2015 Ford Focus. Until you choose, every possible result is shown.

Not sure which Focus you have?
  • Ford UK lists the 2015 Focus under more than one model name: Focus (2010), Focus Electric (2013), Focus (2015), Focus RS (2015) and Focus Electric (2015). Their fuse layouts differ.
  • Ford UK’s Owner Manuals page can find your car’s handbook from its VIN. The page it opens is titled with Ford’s model name, for example “Focus (2010)”.
  • Your printed owner’s handbook, or a franchised dealer with your VIN, can also confirm it.
  • Many cars carry a manufacturer’s label (often called the VIN plate) that can show the build or production date. It is commonly on a door pillar, under the bonnet or at the base of the windscreen, but the exact place varies.
  • Your owner’s handbook, service record or original sales paperwork may show the build date or specification.
  • The first registration date on your V5C logbook is not the build date. Cars are often built weeks or months before they are registered, so it is only a rough guide near a changeover.
  • A franchised dealer can usually confirm the build date and specification from your VIN.
  • Still unsure? Compare the legend on your fuse box cover with each option.

If you can’t confirm it, keep both results in mind and check the fuse box legend before removing anything.

How to replace the fuse safely

  1. Switch off the ignition and all electrical equipment. Take the key out, or move a keyless fob away from the car.
  2. Open the fuse box and find the fuse using the number on the cover legend or the chart on this page.
  3. Pull the fuse straight out with the plastic fuse puller (usually clipped inside the fuse box) or fine-nose pliers.
  4. Look at the metal strip inside the fuse. A broken or burnt strip means it has blown.
  5. Fit a new fuse with exactly the same amperage rating. The number on top and the colour should match.
  6. 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

  1. With the ignition off, pull the relay straight out of its socket. Rock it gently if it is tight.
  2. Relays rarely look damaged when they fail. To test, swap in an identical relay with the same part number from a non-essential circuit.
  3. 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.

  • Battery charge

    Clicking, slow cranking or dim dash lights usually mean a flat battery, not a fuse.

  • Battery terminals

    Loose or corroded terminals can stop the starter even with a good battery.

  • Immobiliser

    A flashing security light can mean the key isn’t recognised. Try the spare key.

  • Clutch or gear selector switch

    Many cars only crank with the clutch fully pressed, or in Park/Neutral on automatics.

  • Starter motor or solenoid

    A single loud click with good battery voltage often points to the starter itself.
