However, many owners encounter difficulties in finding a block, deciphering a circuit, or replacing a burnt-out element.

In this article you will find detailed fuse layout diagram for all generations Karoq (including restyled versions), step-by-step replacement instructions with photos, as well as common mistakes, which are allowed by car owners. We will look at how to identify a blown fuse without a tester, what tools you will need for the job, and what to do if the problem does not go away after replacing it. We will pay special attention hidden fuse boxes, the existence of which many do not suspect - their malfunction can cause unobvious malfunctions in the operation of the car.

Where is the fuse box in the ŠKODA Karoq?

B ŠKODA Karoq provided three main fuse boxes, and their location depends on the year of manufacture and vehicle equipment. Main block (aka SB or Safe Box) is located in the passenger compartment under the dashboard on the driver's side. To access it:

1. Open the driver's door and sit in the seat.
2. Press the block cover latch (located to the left of the steering column, under the decorative panel).
3. Carefully pull the cover towards you - it is secured with latches.

Second block (SCB) is located in the engine compartment next to the battery. The third, additional one, can be located in the trunk (in models with the system Virtual Cockpit or advanced comfort options. Important: In the restyled versions (from 2021) the layout of the fuses was changed - some relays were transferred from the cabin unit to the hood.

ŠKODA Karoq fuse box diagram: decoding

Each fuse in Karoq It is responsible for a particular electrical circuit. Below is an updated modeling scheme 2017–2026 (including facelift). Please note: the safety numbers may vary depending on the configuration (for example, in versions with the DCC or Kessy Additional relays are added.

Number	Ampere	Purpose	Note
F1	10A	System system for engine start-up	Responsible for the immobilizer
F10	15A	Low beam (left headlight)	When you burn out, check the lamp.
F25	20A	Multimedia system Amundsen/Columbus	Often fails at KZ in USB ports
F38	30A	Electrical drive of seats with memory	Only for configurations Style and L&K
F45	7.5A	Parking sensors (front/rear)	When burning, check the integrity of the wiring under the bumper

The complete scheme for your configuration can be found on the back of the lid of the fuse block or in the electronic user manual (section Electrical equipment). If there is no information there, use online catalogue ETKAwhere the circuits are tied to the VIN code of the car.

How to find a diagram by VIN?

Go to the site ETKAenter your VIN. Karoq In the search box and select a section Electrical circuits → block of fuses. The system will automatically load the current circuit for your modification.

How to check the fuse in a ŠKODA Karoq without a tester?

If you do not have a multimeter, you can determine the burned fuse visually or using a simple light bulb. Here. three reliable ways:

• 🔍 Visual inspection: remove the fuse and look at the light - if the thread inside is broken or there are traces of melting, the element is faulty.
• 💡 Checking with a light bulb: Take any 12-volt lamp (for example, from the dimensions), connect its contacts to the terminals of the fuse. If the lamp does not light up, the fuse is burned.
• 🔄 Replacement method: Temporarily install a knowingly serviceable fuse with the same nominal value from another chain (for example, a cigarette lighter). If the device is running, the problem is in the fuse.

⚠️ Attention: Never use fuses with large denomination (eg 20A instead of 10A). This may cause the wiring to catch fire! B Karoq chains are especially sensitive F10 (low beam) and F25 (multimmedia) – their overload often causes failures in the work of the CAN bus.

If the fuse blows again after replacement, this indicates short circuit in the chain. In this case, you need to check the wiring for damage or contact a service center for diagnostics.

Step-by-step instructions for replacing the fuse

Replacing the fuse in ŠKODA Karoq takes no more than 5 minutes, but requires care. You will need:

• 🔧 Tweezers (usually comes complete with the car, attached inside the fuse block).
• 🔋 New fuse same denomination (check the ampere on the old body).
• 📱 Flashlight (for illuminating the unit in the cabin).

Turn off the ignition and make sure all power consumers are off

Find a faulty fuse by circuit or visually

Prepare a new fuse (nominal must match!)

Use tweezers to extract so as not to damage adjacent elements.

Sequence of actions:

1. Open the fuse box cover (as described above).
2. With tweezers, carefully remove the burned fuse. Don't pull the wires!
3. Install the new fuse, making sure it is firmly seated in the socket.
4. Close the block cover and check the circuit operation (for example, turn on the headlights or multimedia).

If after replacement the fuse burns out again, do not repeat the procedure This may indicate a serious malfunction (for example, a circuit in the wire harness under the hood or a malfunction of the control unit). In such cases, it is recommended to conduct a computer diagnostics.

Hidden fuse boxes: where to look?

In addition to the main blocks, ŠKODA Karoq yes supplementary moduleswhich are not mentioned in the standard manual. Their malfunction can manifest itself with non-obvious symptoms: from spontaneous inclusion of wipers to malfunctions in work. Adaptive Cruise Control (ACC).

Where to look:

• 🚗 Under the glove compartment: in models with 3-zone climate control Here is a relay unit for fans and a cooling pump.
• 🔌 Behind the back of the trunk: safety-guard Virtual Cockpit And the rear USB ports.
• 🔋 Next to the battery: chain-block Start-Stop (only in versions with engines) 1.5 TSI and 2.0 TDI).

To access these blocks, it may be necessary to remove the decorative panels. For example, for a block under the glove compartment, it is necessary:

1. Open the glove compartment and take out all the contents.
2. Press the locks on the sides and pull the panel on yourself.
3. The block of fuses will be located on the right, behind the plastic cover.

⚠️ Attention: When working with the blocks in the trunk, turn off the battery! V Karoq with the system Kessy circuits remain energized even when the ignition is turned off, which can lead to short circuit.

Common problems and their solutions

Owners ŠKODA Karoq often encounter typical faults related to fuses. Here are the most common cases and how to resolve them:

Symptom	Probable Cause	Solution
Windshield wipers don't work	Fuse burned out F30 (25A) or relay J317	Replace the fuse, check the relay. If the problem remains, diagnose the motor wipers.
Multimedia is not included.	fuse F25 (20A) or a break in the chain CAN-Low	Replace the fuse, check the connectors behind the head unit.
Spontaneous turning on of the light	Relay fault J439 (comfort block)	Replace the relay, update the comfort unit software through ODIS.

If the fuse blows again, don't ignore the problem. For example, frequent burnouts F10 (passing beam) may indicate:

• Breakage in the lamp headlight (replace the lamp with a quality one, for example, Osram Night Breaker).
• Oxidation of contacts in the headlight unit (clean contacts with alcohol).
• Wiring damage in the harness under the hood (check the insulation near the battery).
