Does this come with the mounting hardware and brackets?

The mirror assembly ships ready to mount at the factory attachment points. You'll need a screwdriver and basic hand tools to remove your old mirror and secure this one in place—fasteners are standard OEM hardware.

Will the power and heating functions work right away after installation?

Yes, if your vehicle's mirror wiring is intact. Plug the factory harness into your car's existing connector, then test the power adjustment and defrost switches on your door panel. If circuits are broken, you'll need to trace and repair the wiring first.

Is there any prep work before I install this?

Inspect the mounting points on your door for damage or corrosion—clean them if needed so the new mirror sits flush. Check that the factory wiring connector inside your door is clean and accessible. No painting or surface prep is required on the mirror itself.
