The video above shows how to replace blown fuses in the interior fuse box of your 2002 Infiniti Q45 in addition to the fuse panel diagram location. Electrical components such as your map light, radio, heated seats, high beams, power windows all have fuses and if they suddenly stop working, chances are you have a fuse that has blown out. If your Q45 is experiencing electrical problems, you should always check the fuses first, because they are relatively easy to check and cheap to change. Some Infinitis have multiple interior fuse boxes including in the trunk - the video above will show you where the interior fuse box of your 2002 Q45 is located. If your Q45 has many options like a sunroof, navigation, heated seats, etc, the more fuses it has. Some components may have multiple fuses, so make sure you check all of the fuses that are linked to the component in question.
If you need to replace a blown fuse in your Q45, make sure you replace it with one that has the same amperage as the blown fuse. If checking and replacing the fuse for the component in question doesn't work, we recommend seeking assistance from a trusted professional mechanic. They should be able to figure out if the component needs to be replaced or if there is a short or some other problem with your Q45.
