The Astra is a compact car designed and produced by the German manufacturer Adam Opel AG since 1991. It serves as the continuation of the Opel Kadett model line, which originated in 1962. In this article, we will examine the fuse box diagrams and relay assignments for the Opel / Vauxhall Astra (second generation; chassis code G; T platform) covering model years 1998, 1999, 2000, 2001, 2002, 2003, and 2004.
Below you will find power distribution box locations and photo references. Fuses for the “Cigarette lighter” and “Fuel pump” are highlighted in bold.
Underhood Fuse & Relay Boxes
The engine compartment houses two distribution units: a main fuse block and a relay box.

Passenger Compartment Fuse Box
The interior fuse box is located on the driver’s side under the dashboard, behind the glove compartment.
To access the fuses, squeeze the side retainers, lower the glove compartment fully, and detach it. Then turn the retaining screws 90° and remove the carrier. Specific fuse block configurations depend on the model year.
