The invention discloses a vehicle heater fault detection method and device and a vehicle. The vehicle heater fault detection method comprises the following steps: acquiring a communication state of a heater; under the condition that the communication state is abnormal, target current of a heating loop where a heater is located is obtained; and when the target current is greater than the first current threshold and the duration is greater than the time threshold, first fault information is generated, and the first fault information is used for indicating that the heater has a fault. According to the embodiment of the invention, the abnormal operation condition of the heater can be found in time, and the working safety of the heater is improved.
