To remove the small bolts inside the door panel of the Mazda 3 driver side mirror, you will most likely need a wrench with a 10 mm or 12 mm head. These sizes are commonly used for small bolts in automotive applications, including those used in the door panels of the Mazda 3.
However, it's always a good idea to double-check with the vehicle's owner manual or consult with a qualified professional to ensure you have the correct size wrench before attempting to remove the bolts.
