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.

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.
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.
Socket and plug
Corroded pins in the towbar socket or the trailer plug cause most trailer light faults. Clean and check them first.
Trailer earth
Flickering or several lights failing together usually points to a poor earth on the trailer side.
Ford-fitted or aftermarket
These fuses cover Ford’s own trailer tow module. An aftermarket towbar kit may have its own separate fuse.
