DesignationWhich is responsible for what/what provides

The cost of a set of a new mounting block for the interior is from 2500 - 2800 rubles, for the engine compartment - from 2300 rubles. Individual modules from 200 – 250 rubles (originals), high-quality analogues from 180 rubles.

Characteristic signs of faulty fuses

• Mechanisms, equipment are inactive, the power circuit is not damaged, complete circuits, terminals, limit switches;
• The modules in the mounting block are heated, the temperature regime is unusual;
• The smell of melted plastic can be heard in the car interior and engine compartment;
• An indicator on the dashboard indicates a malfunction in the equipment;
• The car engine does not start.

Typical causes of fuse failure

• Failure to comply with the deadlines for scheduled technical inspections and replacement of worn-out elements;
• Purchase of non-original consumables (modules);
• Violation of installation technology;
• Mechanical damage to the mounting block;
• Short circuit in the electrical circuit;
• Damage to insulation, terminals, power cable ends;
• Terminal oxidation;
• Weak contact fixation;
• Formation (accumulation) of moisture and condensation, which caused a short circuit in the circuit and equipment breakdown.

Cigarette lighter Skoda Octavia A7: replacing the fuse

All modern cars are equipped with this device. Even non-smoking car owners use it. Instead of its intended purpose, the cigarette lighter socket is used as a standard 12-volt outlet for connecting electronic devices:

• tire inflation pump;
• electronic charger for a mobile phone or tablet;
• DVR monitoring the current traffic situation;
• a navigator that calculates a suitable road;
• portable lighting lamp;
• compact vacuum cleaner;
• fan.

A cigarette lighter failure can lead to some hassle or inconvenience. To avoid them, you should know how to replace or repair the cigarette lighter on a Skoda Octavia A7 or A5.

The design and principle of operation of the cigarette lighter

The device is made as follows. The cigarette lighter device is similar for all Skoda models, including Fabia, Rapid or Octavia. Inside the front panel there is a metal socket to which three wires are connected.

1. Main plus (red). Comes to the battery through a protective element (fuse). Responsible for heating the internal spiral.
2. Constant plus (yellow). Connected to a light filter. Responsible for the correct operation of the backlight.
3. Constant minus (black). A mass with one end coming to the body of the device, and the other to the body of the car.

The Octavia A7 cigarette lighter itself is inserted into the connector, inside of which there is a metal spiral. When you press the button, the contacts close and the spiral is exposed to thermal effects. As soon as it heats up to a temperature sufficient to light a cigarette, a special thermal relay snaps the device into its initial position.

Causes of cigarette lighter malfunction

Over time, the device may fail. There are several reasons why you need to remove and repair the cigarette lighter on the Skoda Octavia A7.

1. Blown fuse. The cigarette lighter safety element is a switch that protects the wires from melting or fire in the event of a short circuit. Each section of the electrical circuit School Octavia A7 is designed for a certain current strength. If the maximum value is exceeded, the cigarette lighter fuse blows. You need to get to the mounting block and change the element. The cigarette lighter fuse of the Skoda Octavia A7 with index F24, rated 25 amperes, must be replaced.
2. Short circuit. If the new cigarette lighter fuse on the Skoda Octavia A7 has burned out again, then there is a high probability that the wires are shorted. It is necessary to open the engine compartment and check the battery voltage with the ignition off. Then we turn it on and check the voltage again using a tester. If there is a drawdown of more than 0.5 volts, then a “short one” is walking along the circuit.
3. It is necessary to inspect all wires: there should be no kinks or breaks, the insulation must be intact and not melted. It is worth checking all the cigarette lighter wires for breaks. We take a tester and then check the cables for resistance. If a break is detected, solder the wire or replace it with a new one.
4. Unreliable contacts. Over time, the fixing antennae become loose due to the constant connection of foreign devices, and plaque may form on the contacts themselves. It is not necessary to change the cigarette lighter on the Skoda Octavia A7 - just clean the contacts with a file or sandpaper and bend them for reliable fixation.
5. Burnt out cigarette lighter coil. A thin nichrome thread is installed inside the device, which is constantly heated and cooled. Over time, it may burn out. Repairing it is impractical - it is advisable to install a new cigarette lighter on the Octavia A7.
6. Faulty backlight bulb. Especially for searching for a socket in the dark, the cigarette lighter on the Octavia A7 has a light filter. The light bulb located inside may burn out. It is necessary to disassemble the device and replace the burnt out element.

Replacing the fuse

One of the most common cigarette lighter failures is the failure of the protective element. In this case, you need to get to the Skoda Octavia fuse box and change the burnt out element. One block is located in the engine compartment: the main relays, fuses for the lambda probe, horn, etc. are located there.

We are interested in the set that is located in the interior of the Octavia A7 car. It is located on the left side of the front panel, behind the decorative cover. To get to it, you need to open the door and disconnect the plastic latches by prying them off with a screwdriver. On the reverse side there is a diagram of the elements:

Fuse box in the passenger compartment

When you open the driver's door completely, you can see the cover at the end of the dashboard, behind which there is a cabin power supply. Opening the lid is easy; just use a flat-head screwdriver.

Engine compartment fuse box

In the Skoda Octavia car, the fuse box installed in the engine compartment near the right wing is covered with a protective cover. In order to unlock it, you need to move the latches.

By removing the cover, you can gain access to the fuses and relays that protect the components located under the hood.

The decoding of the protected electrical circuits of the on-board network of the Skoda Octavia TUR/A5 is given in the table:

Purpose

The installation diagram for fuses and relays is quite extensive, so in order to know which device is responsible for what, you need to familiarize yourself with their features. So, for example, the 5-amp elements of the mounting block in the car interior are responsible for the correct operation:

• ABS and ESC systems;
• driver and passenger airbags;
• climate control and heating systems;
• automatic gearbox;
• rear window wiper electric motor;
• heated front and rear seats.

10-amp are responsible for:

• car central locking;
• switches for external and internal lighting;
• cigarette lighter;
• engine control.

20-amp controls the sockets in the luggage compartment and the windshield and headlight washers of the car.

Fuse box under the hood

We open the hood and the second block is located on the upper right side of the engine. Remove the block cover by moving both brackets down and pulling the cover towards you until it moves away from the body.

In addition to fuses, the module contains relays.

Replacing fuse links

Replacement of blown fuses is carried out in the following order:

1. Turn off the ignition and turn off all energy-consuming devices.
2. Open the cover of the Skoda Octavia TUR/A5 fuse box, which is installed in the engine compartment or inside the dashboard.
3. Determine which of the fuse links has failed. This can be seen from the molten metal insert in the slot in its body.
4. Check the associated electrical circuit for short circuit or overload. Important! It is forbidden to short-circuit the wires to the car body (“ground”), checking the integrity of the wiring for a “spark”. In addition, it is not recommended to use metal tools when working with fuses - you can accidentally cause a short circuit in a working circuit.
5. Take plastic tweezers (located on the inside of the lid) and use it to remove the failed fuse-link from the seat.
6. Using plastic tweezers, install a new fuse-link of the same rating in the appropriate seat. Attention! When replacing, it is not allowed to use fuses of a different rating, homemade “bugs” and fuses of a different design.
7. If, after replacement, the new fuse link fails again, you must contact a certified service station to check the electrical equipment using appropriate equipment.

Replacement

• First you need to turn off the ignition, and it is best to remove the terminals from the battery.
• Carefully inspect the safety block for burnt-out inserts.
• Using tweezers, remove the old (faulty) fuse from the socket.
• The same tools are used to put a serviceable part in place.

Important! You cannot install new protective elements of a higher rating instead of the required ones. In this case, there is a risk of fire.

If, after installing a new protective device, it burns out, this means that the entire electrical circuit needs to be checked or there is a problem with the vehicle's electrical equipment.

Experienced drivers who have driven tens of thousands of kilometers always keep spare protective devices in the trunk for all occasions.

One electrical consumer can be protected by several fuses. One fuse can protect the circuits of several electrical consumers.

In general, the process of replacing the inserts of the Skoda Octavia A5 safety block is simple and any driver can do it independently. The main thing is to do everything on time. If the fault cannot be identified and eliminated, you should contact a service station.

Installing the glove box

• Hook the glove box onto the fasteners (A) (Fig. 214).
• Insert the glove box in the opposite direction of the arrow (4).
• Insert the stopper and lock it with a screwdriver in the opposite direction of the arrow (3).
• Insert the side cover in the opposite direction of the arrow (2).
• Press the side cover in the opposite direction of the arrow (1).
• Close the glove compartment.
