Owners Skoda Kodiaq sooner or later you have to face the need to check or replace fuses. The operation of all electrical equipment depends on their serviceability - from headlights and power windows to the multimedia system and driver assistance system. However, find the correct fuse in relay and fuse blocks not always easy: Kodiaq there are several of them, and each is responsible for their own circuits.
In this article we will take a detailed look at where all the fuse boxes are located in Skoda Kodiaq (including restyled versions 2020β2026), we present decoding of circuits indicating the fuse number, its rating and the protected circuit. You will also learn how to correctly remove and replace a fuse without damaging the contacts, and what typical mistakes lead to re-burnout even after replacement.
Where are the fuse boxes in the Skoda Kodiaq
B Skoda Kodiaq There are three main locations for fuses and relays:
- π§ Main unit in the cabin (under the steering wheel, to the left of the pedals) - contains most of the fuses for the electronics and lighting.
- π Block under the hood (near the battery) - this is where the high current fuses are located (for example, for the cooling fan or ABS).
- π Additional unit in the trunk (behind the right trim) - is responsible for the rear light circuits, 12V sockets and some options (for example, heated seats).
The most popular is salon unit, since this is where the fuses for the cigarette lighter, radio, power windows and other frequently used systems are located. To access it, you must:
- Open the driver's door and move the seat all the way back.
- Press the latch of the unit cover (it is located at the bottom, under the steering wheel).
- Carefully pull the cover towards you - it will be removed along with the fastener.
β οΈ Attention: Do not use force when removing the cover! B Kodiaq 2021-2026, the mount is plastic and may break if moved suddenly. If the lid does not budge, check to see if it is caught on the mat.
- Only in case of malfunction
- Once a year for prevention
- Never checked
- I donβt check it myself, I go to a service center
Deciphering the fuses in the Skoda Kodiaq cabin unit
Cabin fuse box in Skoda Kodiaq contains up to 50 fuses and relays, responsible for different circuits. Below is a table with a breakdown of the most popular elements (relevant for all generations, including the 2020 facelift).
| Number | Rating (A) | Protected circuit | Notes |
|---|---|---|---|
| F3 | 10 | Cigarette lighter/socket 12V (front) | It often burns out when using powerful devices (vacuum cleaner, compressor). |
| F10 | 15 | Power window control unit (driver's door) | If all the windows do not work, also check the relay K12. |
| F20 | 7.5 | Multimedia system (radio, navigation) | When replacing, turn off the ignition for 5 minutes to reset the errors. |
| F30 | 20 | Heated front seats | If it burns out, check the resistance of the heating elements. |
| F45 | 15 | Parking sensors (front/rear) | When replacing, calibrate the system through VCDS or in the service. |
Full diagram for your version Kodiaq can be found on the back of the safety lock or in instruction manual (Section "Electrical equipment"). If you have additional options (for example, Skoda Travel Assist or Virtual Cockpit), some fuses may have a different denomination.
Turn off the ignition and remove the key from the lock
Find the circuit on the block lid or in the manual
Prepare tweezers (usually complete with the machine)
Use a safety lock of the same denomination only.

Fuses under the hood: what you need to know
Fuse box under the hood Skoda Kodiaq located next to the battery and covered with a black plastic cover. Here are power fuses (from 30 to 100 A), responsible for:
- β‘ Generator and battery charging circuits.
- π₯ Cooling fan (often burns out when there is a short circuit in the fan motor).
- π¨ ABS/ESP - If there is a malfunction, the lamp on the dashboard lights up.
- π‘ Xenon/LED headlights (if installed).
The special feature of this block is "maxi" type fuses, which differ in appearance from standard βminiβ fuses in the cabin. To replace them, you will need a flat screwdriver or a special puller (sometimes included with the machine).
β οΈ Attention: Never quickly replace fuses under the hood with a piece of wire or foil! This may lead to fire in the engine compartment due to high currents. For example, a fan fuse (F1, 50 A) when shorted is capable of melting the insulation of adjacent wires.
If after replacement the fuse blows again, this is a signal about short circuit in the chain. In such cases it is necessary:
- Disconnect the consumer (for example, disconnect the fan connector).
- Test the circuit with a multimeter in resistance test mode.
- If a short circuit is detected, eliminate the cause (most often it is frayed insulation or oxidized contacts).
How to check a fuse without a tester?
If you donβt have a multimeter at hand, you can visually inspect the fuse in the light - the blown thread will be broken. You can also use the βreplacement methodβ: install a known-good fuse of the same rating. If the device worked, the problem was in the fuse.
Relay in Skoda Kodiaq: purpose and typical faults
Together with fuses in blocks Kodiaq installed relay, which control the activation of powerful consumers (for example, a starter, headlights or a fuel pump). Unlike fuses, relays rarely fail, but their malfunction can be manifested by the following symptoms:
- π Clicks without operation (for example, you can hear the fan relay operating, but it does not turn on).
- π« Complete lack of reaction (for example, the headlights do not work or the starter does not turn).
- π₯ Relay housing overheating (can be determined by touch).
Below is a table with the most important relays in the cabin unit:
| Designation | Purpose | Symptoms of a problem |
|---|---|---|
| K1 | Starter relay | The engine does not start, there is a clicking sound when turning the key. |
| K5 | Fuel pump relay | The engine stalls and does not start (no pressure in the fuel rail). |
| K12 | Power window relay | All windows do not work at the same time. |
| K20 | Heated rear window relay | The rear window does not heat, the heating filaments are broken. |
To test the relay you can use replacement method: install a known-good relay with the same number (for example, K1 and K5 often interchangeable). If the device works after replacement, the old relay is faulty.
If the starter relay (K1) clicks, but the engine does not turn over, check the voltage at the control contact (thin wire). If it is not there, the problem is in the ignition switch or immobilizer.
How to replace a fuse or relay: step-by-step instructions
Replacing the fuse in Skoda Kodiaq - a simple procedure, but requires care. Follow this algorithm to avoid errors:
- Turn off the power. Remove the key from the ignition and open the door (in some cases it is enough to turn off the ignition, but for fuses under the hood it is better to remove the battery terminal).
- Find the faulty fuse. Use the circuit on the block cover or a multimeter in test mode (the resistance of a good fuse is 0 Ohm).
- Remove the fuse. Take tweezers (usually found in the fuse box) and carefully pull it out without touching other contacts.
- Install a new fuse. He must be same denomination! Using a high current fuse may cause a fire.
- Check the operation of the circuit. Turn on the ignition and check if the device works. If the fuse blows again, look for a short circuit.
To replace the relay:
- Gently pull the relay up (sometimes you may need to wiggle it a little from side to side).
- Install the new relay, aligning the legs with the connector.
- Press until you hear a click - this means that the relay is seated.
β οΈ Attention: Do not touch fuse or relay contacts with bare hands if voltage is applied to them (for example, when the ignition is on). Static electricity or accidental short circuits can damage electronic control units.
If after replacement the fuse immediately blows, DO NOT try to install a fuse of a higher rating! This may cause damage to the wiring or even a fire. It is necessary to look for the cause of the short circuit.
Common Kodiaq fuse problems and their solutions
Owners Skoda Kodiaq often encounter repeated blown fuses in the same circuits. Let's look at the most common cases and ways to eliminate them:
- π Cigarette lighter fuse (F3, 10 A). It burns out when connecting powerful devices (vacuum cleaner, compressor). Solution: Use the cigarette lighter in the trunk (fuse
F50, 20 A) or connect devices through a protected splitter. - π Cooling fan fuse (under hood, 50 A). It burns out due to a jammed fan motor. Solution: Check fan rotation manually (with the ignition off) and replace the motor if necessary.
- π‘ Headlight fuse (F25, 10 A). Burns out when installing LED lamps with incorrect polarity. Solution: Return halogen lamps or install LEDs with a canbus (stabilization unit).
- π Audio system fuse (F20, 7.5 A). Burns out when there is a short circuit in the speakers or amplifier. Solution: Unplug the speakers one at a time to find the faulty one.
If a fuse blows for no apparent reason, check:
- Condition of contacts in the block (oxidation or burning).
- Integrity of wire insulation in the corresponding circuit.
- The operation of the consumer (for example, if the fuel pump fuse blows, check the pump itself for jamming).
What to do if the fuse is intact, but the device does not work?
In this case, the problem may be:
- Wire breakage or contact oxidation.
- Malfunctions of the device itself (for example, the window lift motor burned out).
- Failure of the control relay or control unit.
For diagnostics, you will need a multimeter and an electrical circuit diagram.
FAQ: Frequently asked questions about fuses in Skoda Kodiaq
Can fuses of a different rating be used?
No, this is strictly prohibited! The fuse is designed for a certain current, and if you install a fuse with a large rating, this can lead to overheating of wiring and even fire. If the fuse constantly blows, you need to look for the cause (short circuit or faulty consumer).
Where can I find the fuse diagram for my Kodiaq?
The diagram is printed on the back of the fuse box cover. It can also be found in instruction manual (section "Electrical equipment") or on the official website Skoda in the "Documentation" section. For restyled versions (2020β2026), the schemes may differ - check by VIN code.
Why does it blow again after replacing the cigarette lighter fuse?
This happens due to:
- Using powerful devices (more than 120 W), for example, a car vacuum cleaner or compressor.
- Short circuit in the socket (check the contacts for melting).
- Malfunctions of the cigarette lighter itself (for example, a short circuit in the heating coil).
Solution: Use a protected power strip or connect powerful devices directly to the battery via crocodile clips.
How to test a relay without replacing it?
You can check the relay with a multimeter:
- Set the multimeter to dial mode.
- Connect the probes to the contacts
85and86(relay coil) - resistance should be 50β120 Ohms. - Apply 12V voltage to the contacts
85and86- there should be a click. - Check the resistance between
30and87- in the off state it should be β, in the on state - 0 Ohm.
If at least one of the tests fails, the relay is faulty.
What to do if the fuse is intact, but the device does not work?
In this case, the problem may be:
- Broken wire or oxidation of contacts in the circuit.
- Malfunctions of the device itself (for example, the window lift motor burned out).
- Failure of the control relay or control unit.
- A blown fuse in another block (for example, there may be two fuses for headlights - in the cabin and under the hood).
For diagnosis you will need multimeter and electrical diagram.
