Fiat Punto II 188 (1999-2003) – Fuse Box and Relay Diagrams

Fiat Punto II 188 (1999-2003), before the facelift, has a cabin fuse and relay panel below the driver’s side dashboard and another protected carrier next to the battery under the bonnet. The exact arrangement depends on 1.2 petrol, 1.8 16V, 1.9 diesel, air conditioning, ABS, electric power steering and the Speedgear/automatic transmission. The first facelift cars appeared in 2003, so compare the actual fuse holder rather than relying on registration year alone.

All 65 documented rows from the original Polish guide have been preserved: 25 interior fuses, four cabin relays, 24 engine fuses and twelve engine relays. The two original schematics are repeated beside their respective fuse and relay tables. The period Haynes workshop manual covers 1999-July 2003 1.2 petrol Punto models, not the diesel and 1.8 engines. The broader engine variations in this article must therefore be checked against their own factory fuse cards.

Where are the fuse boxes on the Punto II 1999-2003?

Dashboard panel: switch off the ignition and all electrical consumers, then locate the low cover to the left of the steering column, near the driver’s knees. Loosen the two plastic quarter-turn or screw fasteners along the upper edge, pivot the trim down and compare the cavities with the stamped numbers F12-F53. The layout is not a continuous sequence: vacant positions and other numbers can be absent on the actual card. Refit both fasteners when finished. Right-hand-drive trim placement can differ.

Engine compartment: open the bonnet with the cooling fan stopped and find the black fuse carrier next to the battery. Release its retaining cover clips and lift the lid without pulling harnesses. The engine unit protects the ECU, starter/ignition, electric power steering, ABS, fans, fuel pump and lamps. Large MAXI links should only be serviced using appropriate battery isolation, and their current rating must match the installed engine.

Passenger compartment – 25 source entries

F44 (20 A) powers the front cigarette lighter/12 V socket. F51 (7.5 A) provides number-plate and dashboard illumination, not the 20 A socket power. F40 (30 A) protects the heated rear screen, F43 (30 A) the front wiper and wash pumps, F52 (15 A) the rear wiper, and F38 (20 A) central locking. F33/F34 have no assignment in this documented cabin card.

Dashboard relay positions R1 and R11-R13

These four entries identify high-beam, rear-window demister, main electrical supply and supplementary supply relays. They are relay sockets rather than blade fuses, so no interchangeable amp rating is assigned in the second table column. Equipment fitment differs by vehicle.

Under-bonnet protection – 24 fuse/MAXI entries

F1 (70 A) is the main standard dashboard supply and F2 (40 A) the optional equipment feed. The starter/ignition supply uses F3 (20 A), while ABS uses F4 (50 A) and electric power steering uses F5 (60 A). F6 (30 A) is the radiator fan first-speed branch; F7 (40 or 50 A) depends on engine and air conditioning. F8 (30 A) supplies the cabin blower, not the radiator fan.

The powertrain differences are particularly important: F20 is 15 A for variable valve timing on some 1.8 16V petrol cars or 20 A for the heated diesel fuel filter. F21 (15 A) feeds the fuel pump or the 1.9D stop solenoid, while F22 (20 A) feeds injection/ignition and the fuel-pump circuit on 1.2 8V. F54 (60 A) protects diesel glow-plug preheating. These are engine-specific allocations, not simultaneous equipment for all Punto II variants.

Engine compartment relays R2-R20

Separate relays switch the headlamps, horn, A/C compressor, both radiator fan speeds, cabin ventilation blower, engine ECU and fuel pump. The front fog lamp, headlamp washer, diesel fuel heater and automatic gearbox relays are installed only on appropriately equipped cars. Do not assume that an unpopulated socket is a fault.

Pre-facelift versus later Punto Classic

The most easily confused cabin supply is the rear demister: the pre-facelift car shown here uses F40 (30 A), while the later 2004-2011 Punto Classic guide specifies F40 (25 A). Early engine ECU and ABS supplies also have version-specific ratings. Some 2003 registrations can belong to the later facelift. Compare the original box layout and the factory fuse card to prevent fitting a higher-rated fuse from a related model.

For the revised car, follow the dedicated Fiat Punto II Facelift / Classic (2004-2011) guide. The English Fiat index lists the manufacturer’s other model-specific electrical diagrams.

Common Punto II electrical symptoms

No power from the lighter: inspect F44 (20 A) in the cabin; debris in the 12 V socket and faulty accessories are frequent causes. Heated rear glass inoperative: check F40 (30 A), R11 and rear-window terminals; never install the 25 A Classic rating or a larger rating without confirming the exact card.

Electric steering or “City” steering warning: inspect engine F5 (60 A) and cabin F35 (10 A), then the battery voltage, earth points and power steering ECU. Front wipers stopped: check F43 (30 A), motor and linkage, while rear wiping uses F52 (15 A).

Radiator fan not operating: check engine F6 (30 A), the appropriate 40/50 A F7 and relays R6/R7, then the resistor and temperature-control circuitry. Petrol engine cranks without starting: F21 (15 A), F22 (20 A) on 1.2 8V and fuel-pump relay R10 may be involved. On a diesel, confirm the 1.9D fuel solenoid and the F54 (60 A) glow-plug link without importing a petrol schematic.
