Fuse box diagram (fuse layout), location, and assignment of fuses BMW X3 (E83) (2003, 2004, 2005, 2006, 2007, 2008, 2009, 2010).
Checking and Replacing Fuses
The fuses protect electrical systems against excessive current. When a device does not work, you must check the fuse element inside the blade fuse for a break/melt.
Look at the silver-colored band inside the fuse. If the band is broken or melted, replace the fuse. Check those fuses first that protect the failed component, but check all the fuses before deciding that a blown fuse is not the cause. Replace any blown fuses with another with the same amperage (same color) and check the component’s operation.
WARNING!
- Before replacing a fuse, make sure that the ignition is off and that all the other services are switched off and/or disengaged.
- Never attempt to repair a blown fuse, and do not replace a defective fuse with a substitute of another color or amperage rating, as this could lead to a circuit overload, ultimately resulting in a fire in the vehicle.
- If the replaced fuse blows again, contact an authorized dealer.
