For most of the issues related with the mirrors, it is impossible to diagnose without the usage of a scanner and proper skill; therefore, it is recommended to address a professional repair shop for any electrical issues or problem. Heated feature includes a circuit controlled by either driver's door module or passenger door module; when both the door modules receive data signal from body control module due to connection to rear defog switch, they provide voltage to the heater circuit of mirror. Also, through the help of a memory system, the mirrors are marked to move to a preset position every time a data signal from the door modules will prompt for it to recall the position set for it.
