The invention relates to a windshield glass electrical property detection method. The method comprises the following steps of collecting a resistance value of each phase of a heating film and a resistance value of each temperature sensor; judging whether the resistance value of each phase of the heating film or each resistance value of the temperature sensor exceeds a limit or not; if the impedance characteristic exceeds the limit, sending a corresponding fault driving signal to prompt that the impedance characteristic has a fault; if all the resistance values do not exceed the limit, the mean value of all the resistance values of the heating film or the temperature sensor being calculated; comparing each resistance value of the heating film or the temperature sensor with a threshold range based on the mean value; if one resistance value of the heating film or the temperature sensor exceeds a threshold range, a corresponding fault driving signal being sent to prompt that the impedance characteristic has a fau
