The Saab 9-3 is a compact executive car produced from 1998 to 2014. A key defining feature was the standard use of turbocharged engines across most trim levels and its premium market positioning relative to its donor platform (the Opel Vectra A). This article provides detailed fuse box and relay diagrams for the first-generation Saab 9-3 (chassis code 9400; GM2900 platform; model years 1998, 1999, 2000, 2001, 2002, and 2003).
Below, you will find fuse panel locations, diagrams, and photos of the power distribution centers. Fuses for the “Cigarette Lighter” and “Fuel Pump” are highlighted in bold for quick identification.
