Rear View Mirrors - Exterior, Heated

The rear window defrost switch controls operation of the heated exterior mirror glass. The heated exterior mirror glass only operates when the rear window defrost system is active. The heated exterior rear view mirror glass deactivates when the rear window defrost deactivates. The heated mirror glass receives voltage from the rear window defrost relay located inside the BJB (Battery Junction Box). The LH (Left Hand) and RH (Right Hand) heated mirror glass does not share the same ground.

Component Description

Heating Ventilation Air Conditioning (HVAC) Module

The DATC (Dual Automatic Temperature Control) system uses inputs from the FCIM (Front Controls Interface Module), FDIM (Front Display Interface Module) and voice commands to provide the interface for the vehicle occupants to control the climate control system. The system uses a remote HVAC (Heating, Ventilation, and Air Conditioning) module that is separate from the control interface. When rear window defrost is selected, the FCIM (Front Controls Interface Module), FDIM (Front Display Interface Module) or voice command communicates the selections through the CAN (Controller Area Network) to the HVAC (Heating, Ventilation, and Air Conditioning) module to turn ON the defrost relay.

The optional heated power exterior mirrors are available with heated exterior mirror glass.
