Rear View Mirrors - Exterior

Rear View Mirrors - Exterior

Principles of Operation

LH and RH exterior rear view mirror glass movement is controlled by the exterior rear view mirror switch and the LH and RH exterior rear view mirror motors. Adjusting the exterior rear view mirror switch to the LH or RH position determines which exterior rear view mirror motor to control.

Heated Exterior Mirror

The rear window defrost switch controls the operation of the heated exterior rear view mirrors. The heated exterior rear view mirrors only operate when the rear window defrost system is operating. The heated exterior rear view mirror voltage is supplied by the rear defrost relay output from the Body Control Module (BCM) and Central Junction Box (CJB) fuse 25 (7.5A), which isolates the heated exterior rear view mirrors from the rear window defrost system in the event of a fault.
