Video “Replacing the Opel Astra fuse”

This video shows the process of replacing fuses in a block located in the engine compartment of an Opel Astra.

To identify the vehicle and reliably select the Opel Astra J Hatchback fuse box , you should carefully select the vehicle modification. To do this, use clarifying information with data containing: power, measured in horsepower (example 103 hp), engine size (example 1.6 liters), type (example gasoline) and model + engine code, as a rule, this parameter rarely used, but you can only find it in the vehicle title, you can also pay attention to the drive axle (there are rear, front or all-wheel drive), and a mandatory parameter is the release date, which divides the vehicle model into restyling, pre-restyling, first and last year production.

This data serves to uniquely install spare parts during a certain production period, as manufacturers are constantly upgrading cars off the assembly line.

Fuse location

Before you find out where the power supplies are located in the Opel Astra G, you must remember that the car should always have an additional set of fuses. If one element fails, it is advisable to immediately replace it, but in no case should you use wire.

Some car owners take an ordinary piece of wire or a paper clip and place both ends of it in the place of the burnt fuse. They motivate this by the fact that “there’s nothing wrong with it, if you drive like this for a short time before replacing the fuse.” But it is strictly forbidden to do this, otherwise it may be necessary to replace the power supply.

Power supply circuit

On Opel Astra G models, most of the fuses are located in the block, which is located under the dashboard of the car. In particular, it is installed under the dashboard on the left side opposite the driver's seat behind the glove compartment. To get to the power supply unit, you need to dismantle the facing part of the small items box, then pull the bottom of the unit and bring it into working position. Below is a diagram of the device's location.

In addition, these car models also have an additional unit responsible for protecting electrical equipment and other devices. This protection is optional for the vehicle and this PSU contains eight main fuses. The power supply is located in the engine compartment on the driver's side. Below are diagrams of both blocks.

Purpose of fuses

Now let's look at the purpose of the elements of both power supplies.

Designation of power supply components located in the vehicle interior. Some of these elements are reserved, we will skip them in the table.

Designation of elements located in the main mounting power supply installed in the engine compartment.

How to dismantle and replace fuses?

Replacement of elements in the power supply located in the car interior.

1. First, find the small items drawer located on the driver's side of the seat. Empty the glove compartment.
2. Using a wrench, unscrew the screws securing the glove box trim.
3. To put the power supply into working condition, you need to pull it towards you by the lower part.
4. Having done this, you can replace the fuses. To dismantle a burnt element, you can use special tweezers designed specifically for removing components. They are located on the right side of the power supply. Please note: before removing the fuse, you must turn off the device for which the element is responsible. To do this, turn off the ignition in the car or disconnect the battery. To determine whether a component is working, just look at it. The metal thread in it will be burnt out.
5. After removing the old power supply component, install a new one in its place. At the same time, do not forget that the nominal values ​​of the components, that is, the numbers, must match each other. They will also have the same color.
6. After replacing a component, reassemble everything in reverse order.

Let's start replacing the relays located in the power supply in the engine compartment. Before starting the process, you must turn off the ignition and turn off the engine.

In all Opel Astra H models, two fuse boxes are usually installed - in the engine compartment (driver's side) - under the outer trim cover in the trunk (driver's side)

Depending on the configuration of your car, the diagrams of these blocks may be different - with a different number and arrangement of elements.

The fuse box in the engine compartment is located on the left.

Before looking for it, be sure to turn off the engine and turn off the ignition (turn the key to the OFF position). If you do not do this, you may receive an electric shock or short circuit some contacts with a screwdriver, which may result in a fire.

To open the cover, you can use a screwdriver. There are two clips on the left side of the cover.

Insert a screwdriver into the gap between the cover and the clip - bend the latch a little and lift the cover so that it does not latch when you release it - do the same with the second clip - lift the cover up (to a vertical position), after which the cover can be removed by pulling it up and removed .

In some Opel models (opel astra a), the fuse box consists of two parts. You can remove the cover from the large relay and fuse mounting block by pressing on both sides on the internal clips that hold the cover tightly to the body.

The cover can be removed from the main fuse mounting block by simply pulling it upward. It contains the main fuses.

Under the cover you will see a set of fuses and relays.

Each fuse is responsible for a separate device in the car and is designed for a specific current, so it will be useful to know the fuse ratings.
