Fuses and relays in the Astra H can be found in two places: in the engine bay and the luggage compartment.
Fusebox in the luggage compartment exists in two variants ("big" i "small") - depending on vehicle equipment.
A car with a variant "small" is devoid of REC module (Rear Electronic Control).
Some circuits are protected by several fuses.
When replacing the fuse, be sure to turn the respective circuit and the ignition off!
Do not replace the fuse until the cause of the fault has been remedied. Especially if in a short time after the replacement, the new fuse also blows.
