If you’re driving a first-generation Mazda CX-9 (TB), you’re probably curious about the fuse box diagrams for your ride. From 2006 up to 2015, Mazda produced these beauties, and we’ve got the scoop on where those fuse panels are hiding inside your car, plus what each fuse actually does.
Your Mazda CX-9 from 2007 through 2015 houses its fuse panels in different spots. Some are tucked away under the hood, while others are chilling out inside the cabin. It’s like having a secret map to keep your Mazda running like a champ.
