Which 2013 Focus do you have?

The heated rear window fuse differs between versions of the 2013 Ford Focus. Until you choose, every possible result is shown.

Not sure which Focus you have?
  • Ford UK lists the 2013 Focus under more than one model name: Focus (2010) and Focus Electric (2013). 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.

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.

  • Only some lines clear

    If parts of the screen clear and others don’t, one of the printed heating lines is broken. A fuse fails all or nothing.

  • Connectors on the glass

    Power reaches the glass through small tabs at each side. Check both are still attached.

  • Engine running

    Some cars only power the heated rear window with the engine running.
