Why's my Mazda 2 power mirrors not working?

The most common reason that the power mirrors are not working in Your Mazda2 are going to be because the fuse has been blown on them. You're going to want to access the fuse box under the hood of the vehicle. It's going to be near the battery. You'll have to remove a lid off the top of it in order to access the fuses. If replacing the fuse didn't fix it then it's possible the wiring has become damaged and will need to be replaced. You'll probably want to have a professional take a look at this.
