The Saab 9-3 is a compact executive car produced from 1998 to 2014. A key feature of the model line is the extensive use of turbocharged engines across most production variants, along with a more premium market positioning compared to its platform donor. The second generation shared GM's Epsilon platform with the Opel Vectra and Cadillac BLS. Below is a detailed reference guide for the fuse box diagrams and relay assignments for second-generation Saab 9-3 (chassis code YS3F; GM Epsilon platform) models covering the 2003–2012 model years.
This guide provides the layout diagrams and photos for each power distribution center. Fuses controlling the “Cigarette Lighter” and “Fuel Pump” circuits are highlighted in bold.
In the Engine Compartment
Two fuse boxes are located in the engine compartment.
