BMW 3 Series E36 Fuses and Relay Diagrams

DIY


In this guide, we'll explain the location of the fuses and relays in the BMW 3 Series E36 (1990 – 2000).

In this guide, we will try to figure out where the fuses and relays are located on BMW 3 series E36 generation cars (1990 – 2000).

On vehicles with petrol engines, the fuses are located in a fuse box in the rear of the engine compartment, on the left side. The circuits protected by the fuses are indicated on the cover of the unit.

On vehicles with diesel engines, the fuses are located in two boxes, one in the engine compartment and one under the rear seat. The fuses are of the plug-in type, each with its own color and gauge of fusible link. There is also an 80A fuse installed near the battery under the rear seat that protects all circuits powered directly from the battery.
