Fuses, Fusible Links & Circuit Breakers for 2005 Bmw 325?

The fusible link is a short length of wire, integral with the engine compartment wiring harness and should not be confused with standard wire. The fusible link wire gauge is smaller than the circuit which it protects. Under no circumstances should a fusible link replacement repair be made using a length of standard wire cut from bulk stock or from another wiring harness.

Fusible link wire is covered with a special thick, non-flammable insulation. An overload condition causes the insulation to blister. If the overall condition continues, the wire will melt. To check a fusible link, look for blistering insulation. If the insulation is okay, pull gently on the wire. If the fusible link stretches, the wire has melted.

Fusible links are often identified by the color coding of the insulation. Refer to the accompanying illustration for wire link size and color.

Circuit Breakers

Resetting & Replacement

Circuit breakers are located inside the fuse panel. They are automatically reset when the problem corrects itself, is repaired, or the circuit cools down to allow operation again.

Fuses

Replacement

Use the provided plastic fuse puller located in the fuse panel to remove fuses. The upper lid of the fuse panel has a diagram of the fuse locations and amperage ratings for each circuit. The fuse is removed by simply pulling upward on the fuse with the removal tool.

The fuses are easily checked by visual inspection. With the ignition switch OFF pull the fuse out of the holder. Check the fuse filament. It should be continuous and not broken. If the filament is broken, replace the fuse with one of the same amperage rating.

The fuse and relay box on the E30 and E36 models is located in the engine compartment. The E36 models also has relay boxes located under the left side of the dashboard.

Flashers

The flashers are located behind the bottom center of the lower instrument trim panel.

Fuses & Relays

The fuse box is located under the engine hood on the left side, near the upper strut housing or near the battery.

Various relays are also mounted on the fuse box for easy accessibility.
