Steps
Release the door panel trim
Switch off the ignition. Use a putty knife protected with a paper towel to release the handle bezel and door-pull trim. Remove the panel screws, then pull the panel clips free around the edges and support the panel while unplugging the lock connector.
Remove the old mirror
Unclip the mirror harness from the door and disconnect its electrical plugs. Support the mirror from outside while removing its three 10 mm mounting nuts, then feed the harness through the opening and remove the mirror.
Install the replacement mirror
Route the replacement mirror harness through the door and seat the mirror in its mount. Reinstall and tighten the three nuts evenly, secure the harness clip, and reconnect each electrical connector.
Reinstall the panel and verify operation
Align the door panel starting at its upper edge and press the clips into place. Reinstall the screws and door-pull trim, reconnect the lock switch, and secure its bezel. Test the mirror adjustment, lock switch, and door handle before closing the door.
