The invention relates to an automobile air conditioner control system. A temperature adjusting signal collection circuit of the system is connected with a controller; a power module is connected with the controller and is connected with an inner and outer circulation mode actuator, a mode actuator, a temperature actuator and the like through a motor power supply overcurrent protection circuit; a temperature adjusting partial voltage rheostat in the temperature adjusting signal collection circuit is connected between two partial voltage branch resistors; when golden finger copper foil of an outer temperature adjusting knob slides at input ends of different gears, the controller collects two paths of voltage signals, the working temperature of an air conditioner is adjusted according to the voltage difference between the two paths of signals, and the temperature control precision is improved. The motor power supply overcurrent protection circuit supplies power to the actuators through an overcurrent protection circuit composed of a first overcurrent protection audion and a second overcurrent protection audion. Voltage output to the actuators by the controller is monitored by a feedback resistance circuit and a switching tube circuit, and the system stability is improved.
