There is disclosed a vehicle air conditioner device which is capable of continuing air conditioning of a vehicle interior also in a case where a failure occurs in a solenoid valve to change a flow of a refrigerant in each operation mode. A vehicle air conditioner device 1 includes a solenoid valve 17 for cooling, a solenoid valve 21 for heating and a solenoid valve 22 for dehumidifying to switch respective operation modes of the vehicle air conditioner device. A controller changes and executes the respective operation modes of a heating mode, a dehumidifying mode, and a cooling mode. The controller has a predetermined air conditioning mode during failure, and failure detecting means for detecting failure of the solenoid valve. In a case where the failure detecting means detects that the solenoid valves fail in the respective operation modes, the controller selects the air conditioning mode during failure in which vehicle interior air conditioning by the operation mode is achievable, to continue the air conditioning of the vehicle interior.
