A method for controlling a rear glass defroster for a vehicle upon start-up is presented. First, one or more factors are determined, which are selected from a temperature of an environment immediately outside the vehicle, a humidity of the environment, a dew point of the environment, a barometric pressure of the environment, a temperature of a rear glass of the vehicle, a temperature of an internal cabin of the vehicle and a sun load on the vehicle. Next, the one or more factors are compared to one or more corresponding predetermined thresholds or ranges that are indicative of conditions suitable for frost formation on a rear glass of the vehicle. Then, if the comparison indicates that the one or more factors meet the frost formation conditions, the rear glass defroster is activated. A vehicle rear-glass defrost system which uses the foregoing method is also presented.
