Which 2010 Focus do you have?

The heated seat fuse differs between versions of the 2010 Ford Focus. Until you choose, every possible result is shown.

Not sure which Focus you have?
  • Ford UK lists the 2010 Focus under more than one model name: Focus - B4 (C307 post-MCA) and Focus (2010). 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 - B4 (C307 post-MCA)”.
  • 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.

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.

  • One seat or both?

    If only one seat has failed, its own fuse, switch or heating pad is the likely cause.

  • Connector under the seat

    The seat wiring plugs in under the seat. Sliding the seat can strain or loosen this connector.

  • Heating element

    Elements can break inside the cushion, often where you kneel or slide in and out of the car.
