Why would both of your lighter not work in 2005 BMW x5?

If both lighter sockets in a 2005 BMW X5 are not working, it could be due to a blown fuse, as multiple sockets often share the same circuit. Another possibility is a poor connection or damage to the wiring. Additionally, if the lighter sockets are dirty or corroded, they may not make proper contact. Lastly, check if the devices you're trying to use are functioning properly as well.
