Ford Fiesta Mk5 facelift (1999-2002) is the updated version of the 1995-2002 Fiesta family. Depending on the country and catalog, this facelift is also labelled late Fiesta Mk4. The model uses a central dashboard fuse box and an additional under-bonnet fuse and relay carrier. A manufacturing change around September 1999 and differences between petrol, 1.8 diesel and Scandinavian-market equipment mean not every 1999 car uses the same fuse panel.
These five tables preserve all 72 fuse, diode and relay source entries: 22 dashboard fuses, one optional F43 daytime running light fuse, 14 rear-of-cabin relays, 23 engine positions including the three diode sockets and petrol/diesel alternatives, plus 12 engine relays. All three original fuse-box drawings are included. The dashboard listing is consistent with the 2000 Ford Fiesta owner’s handbook for this configuration, but the manufacturing date and label fitted to the car take precedence.
Ford Fiesta 1999-2002 – where are the fuse boxes?
Central interior fuse carrier: switch off the ignition, remove the key, move the driver’s seat back and locate the fuse box under the driver’s side dashboard. Remove the lower plastic access cover to expose the panel. The fuses are numbered in two staggered rows, not consecutively from left to right, so check the printed slot numbering before removing a fuse. Ford used two versions of the module at the rear of this panel; reaching the relays may require opening or removing further trim without forcing harness plugs.
Engine compartment: with the cooling fan stationary, open the bonnet and locate the additional fuse box on the left side of the engine bay. The period owner’s handbook describes removing the adjacent rubber seal and releasing five lid clips. This carrier contains fuses 23-40, three diode positions and the engine/fan/headlamp relays. Keep the cover sealed afterwards and observe proper battery isolation for 40-60 A main fuses.

Central passenger compartment fuse box – positions 1-22
On the shown 2000-2001 European fuse card, fuse 1 (15 A) supplies the front 12 V cigarette lighter/accessory socket, fuse 12 (20 A) the front windscreen wipers and washer, and fuse 16 (30 A) the cabin blower. The list also retains separate heater/demister, brake, lighting, central locking, electric window and airbag protection. Do not compare fuse colors alone with a pre-facelift 1999 car whose assignments may differ.

Supplementary fuse F43 – Scandinavian daytime running lights
F43 (10 A) is documented behind the central fusebox for the daytime-running-light resistor on certain Scandinavian-market vehicles. Cars without factory DRL may have no fuse fitted at this location. This separate position is not part of the ordinary 1-22 front row.
| Pozycja | Amperaż [A] | Chroniony obwód / funkcja |
|---|---|---|
| 43 | 10 | F43 – 10 A daytime running light series resistor, mainly Scandinavian-market cars |
Rear face of central fusebox – relays I-XIV
The cabin module supports ignition, heated front and rear screens and optional daytime-running-light control. The archived 2000 configuration leaves several relay sockets unused. Note that cabin relay III is unoccupied in the documented interior panel, while engine-bay relay III has an active petrol pump or diesel fuel heater function. They are two different physical modules with independent Roman numbering.

Engine compartment fuses 23-40 and diodes D1-D3
The engine box supplies individual left/right dipped and main beams, ABS, petrol fuel injection, diesel fuel heating, radiator fans, horn/lighting through relays and the heated windscreen. The first three table rows represent diodes D1-D3, not fuses with an interchangeable amp rating.
Two engine-specific alternatives are retained: F27 is 10 A for the petrol catalytic/emissions circuit or 15 A for diesel fuel heating; F35 is 10 A for the petrol fuel pump or 3 A for the diesel PATS immobiliser supply. They are not interchangeable within one vehicle. F36-F40 include larger 40-60 A electrical distribution circuits. The old source correctly lists F23 as the left high beam (10 A), not an unused position.

| Pozycja | Amperaż [A] | Chroniony obwód / funkcja |

| D1 | – | D1 – engine control circuit diode, not a fuse |
| D2 | – | D2 – unoccupied diode position |

Engine-bay relay panel I-XII
These relays control air conditioning, engine ECU, the petrol fuel pump or diesel heater, fog lamps, low/high beams, radiator fans, diesel glow plugs and starter. Relay III differs by petrol/diesel engine and relay X is diesel preheating only. All relay amp values are marked “-” because the cells identify relay sockets, not replaceable blade fuses.

1999 transition, Mk4/Mk5 naming and equipment
Cars made around the 1999 facelift may carry a different central fusebox type, especially where a vehicle built before September 1999 is listed simply as Fiesta Mk4 by its owner or parts catalog. The displayed layout is based on the later central-box version used around 2000; confirm with the fuse labels and part numbers of the installed panel rather than transferring a similarly numbered diagram.
Equipment differences can include the heated front windscreen, ABS, air conditioning, factory fog lamps, petrol vs 1.8 diesel and Scandinavian DRL. A missing optional fuse or relay may be correct. Conversely, identical-looking relay housings can have different pin configurations and should not be swapped at random.
Common electrical faults in this Fiesta
12 V cigarette lighter dead: check cabin F1 (15 A), remove the accessory and inspect the socket contacts for conductive debris. Front wipers stopped: cabin F12 (20 A), the wiper motor and the stalk switch. If the wipers work but fail to park, check the control circuit rather than assuming only a fuse fault.
Heated front windscreen not working: inspect engine F37 (40 A) and interior relay II, plus the screen connectors. Rear window heater dead: cabin F4 (20 A), rear relay X and the screen heating strips; the engine power supply F38 (60 A) also feeds relevant high-current cabin consumers.
Headlamp failure: under-bonnet F23/F24 (10 A each) are left/right main beams, F25/F26 (10 A each) left/right dipped beams. Petrol engine cranks but will not start: F35 (10 A) and engine relay III concern the fuel pump, while the diesel version uses F35 (3 A) for PATS instead. The relevant engine control and relay supply must be diagnosed using the actual engine.
ABS warning: engine F30 (3 A), F31 (30 A) and F33 (30 A) when fitted, then diagnostic trouble codes. Cooling fan not engaging: check engine F36 (60 A) as well as relays VIII/IX and the temperature controls before replacing a fan motor.
The contemporary Ford Puma I (1997-2002) has related Fiesta-era engineering, but does not use identical fuse numbering. The later Ford Focus Mk2 facelift is a different Ford electrical platform.
