Fuses and relays in the Astra H can be found in two places:
in the engine bay and the luggage compartment.
Fusebox in the engine compartment exists in two variants (1 i 2).
They differ from each other in that they have different assigned fuses to protect
individual circuits.
Some circuits are protected by several fuses.
Variant 1 is used for vehicles manufactured before facelift (2006) and above, if the are equipped with a big fuse box in the luggage compartment.
So variant 2 can be found in cars manufactured since 2006 and equipped with a small fuse box in the luggage compartment.
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.
