The Opel / Vauxhall Astra H is a compact passenger car produced from March 2004 as a five-door hatchback. Late 2004 saw the introduction of the five-door station wagon (estate) and sporty three-door hatchback (GTC) variants. Below are detailed fuse box diagrams and relay location guides for the Opel / Vauxhall Astra (chassis code H; Delta platform) covering model years 2004, 2005, 2006, 2007, 2008, 2009, 2010, 2011, 2012, 2013, and 2014.
Here you will find power distribution box locations, layout diagrams, and reference photographs. Fuses for the “Cigarette lighter” and “Fuel pump” are highlighted in bold.
