European Ford Focus Mk2 facelift, B4/C307 post-MCA (from 3 December 2007) has two main fuse carriers: positions 1-36 under the bonnet and positions 100-143 beneath the passenger glovebox. This is the facelift version known as Focus Mk2.5, not the preceding model-year fuse system or the North American Focus.
These 106 complete fuse and relay rows retain every engine, gearbox, ST/RS and cabriolet alternative from the original Polish article, as well as unused slots. Some assignments differ between 1.6/2.0 petrol, TDCi diesels and Focus ST/RS. The fuse legend fitted to the car takes precedence over a chart for a different production date.
Ford Focus Mk2 facelift – where are the fuses?
Engine compartment: with the ignition switched off, open the bonnet and locate the main covered distribution housing near the battery. Release the cover clips and identify the numbered 1-36 positions. Large 40-80 A supply links and smaller blade fuses share the housing; follow the manufacturer’s electrical isolation instructions when dealing with high-current connections.
Under the front passenger dashboard: move the passenger seat back, remove the lower trim section below the glovebox, release the retaining fittings, and gently fold the junction box down and toward you to expose the 100-143 fuse carrier. Compare each number with the fuse legend from the vehicle. Refit and secure the assembly before replacing the trim.
Under-bonnet fuses – full positions 1-36
The original C307 facelift engine chart includes radiator cooling, power steering, two main cabin feeds, ABS/ESP, starter, engine management and windscreen heating. F14 (40 A) supplies the right heated-windscreen half and F16 (40 A) the left. F17 (30 A) is used by the factory convertible roof. This assignment is not interchangeable with pre-facelift cards that may show another F1 rating.

Engine compartment relays R1-R14
Equipment changes the purpose of some relay positions. R5 is associated with diesel preheating or selected petrol ventilation control; R12 and R14 also vary by engine. The amp column uses “-” because a relay is not a fuse with an interchangeable blade-fuse rating.

Passenger fuse box – positions 100-143
F109 (20 A) protects the front cigarette lighter and a rear accessory socket. The separate luggage socket uses F119 (15 A) or 25 A with the appropriate factory towing module. F128 and F130 are unused in the documented card. Heated front seats, keyless systems and convertible controls are optional.

Passenger compartment relays
The interior junction assembly contains the petrol fuel pump relay and an equipment-dependent second relay. Some relays may be fitted on the rear face of the module; removing the module without identifying connectors and fasteners risks damage.

| R1 | – | Fuel pump relay, petrol engine |
| R2 | – | Unoccupied relay position or equipment-specific relay |
Focus ST and RS engine fuse differences
Performance variants cannot use the normal 1.6/2.0 engine fuse card without checking their equipment. F26 supplies the permanent PCM feed at 10 A on ST/RS rather than the 15 A automatic-transmission application; F33 can also rise from 10 A to 20 A for the ST/RS heated oxygen sensor. All four original comparison entries are retained.
| Pozycja | Amperaż [A] | Chroniony obwód / funkcja |
|---|---|---|
| F26 | 15 / 10 | 15 A automatic gearbox supply or 10 A ST/RS permanent PCM supply |
| F32 | 10 / 10 | 10 A automatic gearbox supply or 10 A ST/RS fuel injector supply |
| F33 | 10 / 20 | 10 A normal petrol oxygen sensor / diesel intercooler valve, or 20 A ST/RS oxygen sensor heating |
| F35 | 10 / 15 | 10 A ordinary PCM/solenoids or 15 A expanded ST/RS engine control load |
Diesels: F6 (60 A) protects glow plugs, F24 (15 A) supplementary heating and F28 (10 A) glow monitoring. Cabriolets: F17 (30 A) and interior F101 (20 A) may feed retractable-roof electronics. Never assume the same fuse is populated in every body style.
Common Focus Mk2 facelift electrical faults
12 V socket not working: check F109 (20 A) under the passenger dash; a boot socket can be on F119 instead. Remove the adapter and check for conductive debris in the socket.
Only half the windscreen heating works: check F14 and F16 individually and the R7 relay. Wiper problems: cabin F129 (20 A) controls the front wipers and F131 (15 A) the rear. Heated rear window: cabin F105 (25 A).
Petrol engine will not start: F111 (15 A) is the fuel pump supply, in addition to its relay. Headlamp failure: F139/F140 are the right/left high beam (10 A), while F142/F143 protect the right/left dipped beam (15 A).
