The 3rd generation Ford Focus was produced in 2011, 2012, 2013, 2014, 2015, 2016, 2022 and 2022 with sedan, hatchback, and station wagon bodies and was supplied to markets in more than 122 countries, including Russia. This model was restyled in 2014. In our material we will show where the blocks with fuses and relays of the 3rd generation Ford Focus , their description with block diagrams and photographs. We will separately highlight the fuse responsible for the cigarette lighter. We will also show the general location of all electronic control units.
The purpose of the fuses may differ from those presented and depend on the year of manufacture, equipment level and country of delivery of the Ford Focus 3. And if the model generation is not suitable, study other descriptions: Focus 1 and Focus 2.

Replacing the fuse
To change you need to perform a number of steps.
- De-energize the on-board circuit.
- Open the protective panel of the mounting block.
- Remove the module from the slot.
- Here you should find the fuse link number F61.
- Next, using a special tool, remove the fuse from the socket and install a known good one in its place.
You can watch the video to see how to replace the part.

What is he responsible for?
The fusible element has two purposes. In the first modification and the version that underwent restyling in 2012, the essence does not change. The element is directly responsible for the cigarette lighter and the rear socket.
To relieve the load, some drivers install a “smoker” directly from the battery. This makes it possible to connect more powerful equipment to the outlet without the risk of damaging the system.
Fuse diagram
The standard fuse is located in the cabin module and is connected to the on-board circuit at the point where the wiring is broken in front of the consumers and the switch. The entire circuit is protected and there is no chance of damage.
Location
On the third generation Focus, the fuse is located under the glove compartment. The part stays in one place, no matter what modification of the body. It doesn't matter whether it's a station wagon, hatchback or sedan.
To gain access to the module, release the latches of the protective cover and remove it from its seat.
Here the insert is painted yellow and installed in the first left row vertically, fourth slot from the bottom.
