Location
Open the tailgate and look at the left-hand side trim of the luggage compartment, behind a rectangular cover. Unclip the cover at its notch to reveal the fuse carrier; a spare-fuse holder and puller are usually clipped to the inside of the cover.
The Astra J has two fuse boxes: this one in the luggage compartment (body and comfort circuits) and a main one in the engine compartment. Positions differ slightly between hatchback, Sports Tourer and GTC bodies. Fuse assignment varies by equipment level and production year. Always confirm with the label on the fuse box cover or the owner's manual.
