Fuse diagram for Škoda Felicia: where is the block located, decoding and replacement

Owners Škoda Felicia (1994–2001) sooner or later face the need to check or replace fuses. Electrical faults - from non-functioning headlights to heater failure - are often associated with burnt-out fuse links. However, finding an up-to-date fuse box diagram for this model is not easy: in manuals from different years of manufacture, the arrangement of elements may differ, and on forums there is conflicting information.

In this article we have collected detailed fuse diagrams for all Felicia modifications (including 1.3 MPI, 1.6 MPI and 1.9 TDI), indicated their exact ratings and purpose, and also explained how to correctly diagnose and replace fuses without the risk of a short circuit. Particular emphasis is placed on hidden fuses for the ignition relay and fuel pump, which are often overlooked even by experienced car owners.

Where is the fuse box in the Škoda Felicia

B Felicia There are two main fuse blocks:

• 🔧 Main unit — located under the steering column, behind the plastic cover. To gain access, just pull the cover towards you (it is secured with latches).
• ⚡ Additional relay block - located next to the main unit, but can be hidden behind the casing (depending on the year of manufacture). In 1998+ models it is often located separately, under the glove compartment.
• 🔋 Generator fuse - in some versions it is installed separately, next to the battery (fuse on 80–100A in a black case).

Important: in Felicia Combi (station wagon) and Pickup the arrangement of the blocks is identical to the sedan, but a fuse for the rear fog lamp can be added (F25 in some modifications). If you don't find the unit the first time, check the space under the glove box - additional relays for the heating system are sometimes installed there.

Main Unit Fuse Diagram (1994–2001)

Below is a universal diagram for most versions Felicia. Fuse ratings may vary slightly depending on the configuration (for example, in cars with air conditioning a fuse is added F17 on 10A for compressor).

Designation	Rating (A)	Purpose	Notes
F1	10	Interior lighting lamps, instrument lighting	Often burns out when installing LED lamps
F2	10	Direction indicators, hazard warning lights	If both turn signals do not work, check the relay K2
F3	10	Windshield wipers, windshield washer	Models with rear wiper add F23
F7	20	Heater fan	If it burns out, check the heater motor for jamming
F10	15	Low beam (left headlight)	Paired with F11 (right headlight). Denomination may be 10A in earlier versions

The complete diagram for your modification can be found on the inside of the fuse box cover (if it is not worn off). If the inscriptions are illegible, use the color of the wire that goes to the fuse as a guide:

• 🔴 Red - usually powered by a battery (constant "+").
• 🔵 Blue/black — “ground” or control signals.
• 🟢 Green/yellow - ignition or lighting circuits.

How to check a fuse without a tester?

If you don’t have a multimeter at hand, you can visually inspect the fuse using light: the blown thread will be broken. An alternative method is to replace the suspect fuse with a known good fuse of the same rating (for example, F1 and F2 often interchangeable).

Hidden fuses and relays: what is often missed

Many electrical problems in Felicia are connected not with the main block, but with additional fuses and relays, which are not specified in the standard scheme. For example:

• 🔥 Fuel pump fuse - in models with 1.9 TDI often located separately under the hood (next to the pump relay). Denomination - 15A, but in some versions it may be 20A.
• 🔋 Ignition relay (K35) — responsible for powering the ECU and injectors. If it fails, the engine will not start, although the starter will turn.
• 💡 Fog light fuse — in Felicia FL (facelift) can be hidden behind the glove compartment (F24, 10A).

Particular attention should be paid generator fuse (usually 80–100A in a black case). It is located next to the positive terminal of the battery and often oxidizes, leading to loss of charge. If after replacing the fuse it blows again, check:

⚠️ Attention: If the generator fuse blows immediately after installation, do not try to install a fuse of a higher rating - this may lead to a fire in the wiring. First, check the diode bridge of the generator and the condition of the battery terminals.

Check the fuel pump relay (does it click when you turn the ignition on)

Inspect the generator fuse for oxidation.

Make sure the fog light fuse is not “hidden” behind the glove compartment.

Test the ignition relay circuit (K35) for starting problems-->

How to properly replace a fuse: step-by-step instructions

Replacing the fuse in Felicia It seems like a simple procedure, but there are nuances that will help avoid short circuits or failure of electronics. Follow this algorithm:

1. Turn off the ignition and remove the terminal from the battery (especially if you are working with fuses F10–F15related to lighting).
2. Use tweezers from the fuse kit (or plastic tweezers to avoid damaging the block contacts).
3. Install a fuse of the same rating. For example, if you burn out F7 (20A), don't put 25A - this may damage the stove fan.
4. Check the chain after replacement. If the fuse blows again, look for a short (usually in the wiring harness under the hood or in the driver's door).

For fuses responsible for critical systems (e.g. F10/F11 - low beam), it is recommended to carry spare ones with you. B Felicia standard fuses are often used ATO (knife), which can be bought at any auto store.

Common problems with fuses and their solutions

Here are typical symptoms and how to eliminate them:

Symptom	Probable Cause	Solution
Cigarette lighter and radio not working	Burnt out F18 (15A) or contacts have oxidized	Replace the fuse, clean the block contacts with alcohol
Cooling fan does not turn on	fuse F8 (20A) or relay K6	Also check the temperature sensor and wiring to the fan
Wipers only work at one speed	Burnt out F3 (10A) or the relay is faulty K1	Replace the relay (costs about 300–500 rubles), check the wiper motor

If the fuse F16 (10A)responsible for Engine ECU, burns out regularly, the problem may be:

• Short circuit in the wiring harness under the hood (especially near the fuse box).
• Malfunction of the crankshaft position sensor (check resistance with a multimeter).
• Problems with the ground on the body (clean the attachment points of the ground wires).

⚠️ Attention: If after replacing the fuse F16 the engine does not start or runs intermittently, do not try to "reflash" the ECU — first eliminate the cause of the short circuit. Otherwise, the control unit may be damaged.

Upgrading the electrical system: what can be improved

Standard electrics Felicia is not reliable, but it can be improved:

• 🔌 Additional fuse block — install a separate unit for powerful consumers (for example, for a subwoofer or additional headlights). This will relieve the load on the standard wiring.
• 🔋 Low beam relay — in Felicia The headlights are connected directly, which leads to melting of the contacts. Installing a relay will extend the life of the light switch.
• 💡 LED lamps with protection — if you install LEDs in the interior or dimensions, add voltage stabilizers to avoid burnout F1.

When upgrading, be sure to use fuses with current reserve by 20–30%. For example, if the standard fuse for the radio 10A, and you connect the amplifier, put 15A and lay a separate wire with a cross-section of at least 1.5 mm².

FAQ: Frequently asked questions about Škoda Felicia fuses

Where can I find a fuse diagram for my Felicia modification?

The diagram is usually marked on the inside of the fuse box cover. If it is not there, focus on the year of manufacture:

• 1994–1996 - fuses F10/F11 low beam have a nominal value 10A.
• 1997–2001 — denomination increased to 15A, fuse added F24 for fog lights.

For 1.9 TDI The diagram may differ - look for a separate fuel pump fuse (15A) under the hood.

Why does the heater fuse blow out?F7)?

Main reasons:

1. The fan motor is stuck (check that it rotates freely).
2. Short circuit in the wiring (wires under the carpet on the driver's side often fray).
3. Installation of an abnormal fan with increased current consumption.

Solution: replace the motor (part number 1U2 955 021B), check the wiring and install a fuse 25A (temporarily, for diagnostic purposes).

Is it possible to install fuses of a higher rating?

Categorically not recommended. For example, if instead F10 (15A) put 20A, in the event of a short circuit it may burn out:

• Wiring in the harness to the headlight.
• Light switch on the steering column.
• The lamp itself (especially if high-power halogens are installed).

An exception is a temporary replacement for diagnostic purposes (for example, 20A instead of 15A for 5 minutes), but only if you are sure there is no short circuit.

How to check the relay in Felicia?

Most relays in Felicia standard (type 906.3747-01) and interchangeable. To test the relay:

1. Remove the relay from the block (for example, K2 - emergency alarm).
2. Serve 12V to contacts 85 (mass) and 86 (plus). There should be a click.
3. Use a multimeter to check the resistance between 30 and 87 - must be 0 ohm (closed).

If the relay does not click or the resistance is infinite, replace it. The cost of a new relay is from 200 rubles.

What to do if fuses keep blowing?

This is a sign short circuit or increased load on the chain. Follow the algorithm:

1. Disconnect all consumers connected to the problematic circuit (for example, remove the headlight bulb if it is on F10).
2. Test the wiring with a multimeter in the "test" mode - the resistance between positive and ground should be infinite.
3. Check places where wires are frequently chafed:
   • The harness is under the hood near the fuse box.
   • Wires in the corrugation between the door and the pillar.
   • Wiring under the driver's mat (especially if the floors were flooded).

If you cannot find the problem yourself, contact an auto electrician with experience in working with VW Group (platform Felicia similar to VW Polo Classic).
