Fuses and relays Saab 9-5 (YS3E), 1997 - 2009

The first-generation Saab 9-5 was built on the GM2902 platform—a modified and slightly extended (from 2,640 to 2,703 mm) GM2900 chassis shared with the Opel Vectra B. The model underwent two major facelifts: the first in 2001 and the second in 2005. In this article, we provide detailed fuse box diagrams and relay assignments for the first-generation Saab 9-5 (chassis code YS3E; 1997–2009 model years).

This guide details the locations and diagrams for the power distribution boxes. Fuses responsible for the “Cigarette Lighter” and “Fuel Pump” circuits are highlighted in bold.

In the Engine Compartment

Under the hood, there are two power distribution units: the main distribution box (1), housing fuses and relays, and a high-power fusible link box (2) located adjacent to the positive battery terminal.
