To remove the passenger mirror on a Lincoln Mark VIII, first, ensure the vehicle is turned off and the battery is disconnected for safety. Carefully pry off the mirror cover if applicable, then locate and remove the screws or bolts holding the mirror in place. Disconnect the electrical connector, if equipped, and gently pull the mirror away from the door. Reinstallation is the reverse of removal; ensure everything is securely fastened.
