There is disclosed a vehicle air conditioner device which is capable of continuing an air conditioning operation also in a case where a disconnection failure occurs in a solenoid valve to change a flow of a refrigerant in each operation mode. Respective solenoid valves 17, 20, 21 and 22 to change the respective operation modes of a vehicle air conditioner device 1 are constituted so that the flow of the refrigerant changes to a cooling mode when all the solenoid valves 17, 20, 21 and 22 are non-energized. The vehicle air conditioner device executes a cooling mode during failure in which a controller adjusts all the solenoid valves 17, 20, 21 and 22 to be non-energized and operates a compressor 2, in a case where the disconnection failure occurs in one of the solenoid valves 17, 20, 21 and 22.
