Opel Astra K represents the 5th generation of Opel Astra, which was produced in 2015, 2016, 2017, 2018, 2019, 2020, 2021, 2022. During this time, the model underwent restyling. In this publication, you can find a description of the fuses and relays of the Opel Astra K with block diagrams, their locations and photo examples of execution. Let’s highlight the cigarette lighter fuse.
The purpose of fuses and relays may differ from that shown and depends on the year of manufacture, level of electrical equipment and region of delivery of your vehicle.
Block in the cabin
In the car’s interior, the fuse and relay box is located in the middle of the center console, behind the protective cover.
If the fuse cover has a power connector, it must be removed using an adapter and a screwdriver, which should be located in the glove compartment.
