How do you repair the driver's side mirror in a 2003 Mazda?

To repair the driver's side mirror on a 2003 Mazda, first, carefully remove any broken mirror glass and the mirror housing if necessary. Use a flathead screwdriver to pry off the plastic cover, then unscrew the mounting bolts to detach the mirror assembly. Replace it with a new mirror or glass, reattach the assembly, and secure it with screws. Finally, snap the plastic cover back into place and ensure the mirror is aligned correctly.
