What Is a Fuse Diagram?
A BMW E90 fuse diagram is a map of all the fuses in your car. It tells you which fuse controls what electrical component, from the headlights to the radio to the air conditioning. If something isn’t working in your car, the fuse diagram is a great place to start troubleshooting.
The fuse box in the BMW E90 is located under the hood on the right side of the engine compartment. The fuse box cover has a diagram of the fuses and their respective functions.
How to Read a Fuse Diagram
Reading a fuse diagram can be confusing at first, but it’s actually quite simple. Each fuse has a number that corresponds to its location on the diagram. The fuse diagram will also tell you the amperage rating of each fuse, which indicates the maximum amount of electrical current the fuse can handle before it blows.
The fuse diagram may also use different symbols to indicate different types of fuses. For example, a blade fuse may be represented by a rectangle with a line through the middle, while a glass tube fuse may be represented by a rectangle with a wavy line inside.
