Claim:
1. A control device for an air conditioner which conducts an air conditioning in an air-conditioner unit, into which inside air or outside air is drawn, using an evaporator and a heater core, the control device comprising: a first actuator and a second actuator which drive a plurality of dampers switching air passages in the air-conditioner unit; and three half bridged circuits which control the first actuator and the second actuator by sharing one of the half bridged circuits, wherein the first actuator is connected to an inside/outside air switch damper, of the plurality of dampers, which switches between the inside air and the outside air, and the second actuator is connected to at least one air mix damper of the plurality of dampers; wherein the first actuator and the second actuator are connected to the three half bridged circuits in a manner that a rotational direction of the first actuator at an inside air mode at which the inside/outside air switch damper closes an outside air intake port and a rotational direction of the second actuator to close an air intake port of the heater core by the air mix damper are opposite from each other.
