Yes, a faulty thermostat can cause the heating system to blow cold air. If the thermostat is not functioning properly, it may not signal the furnace to turn on and produce warm air. It's important to have a professional inspect and replace the thermostat if needed to ensure proper heating.
If the unit is a heat pump, and the fan switch is set to ON, the unit compressor will cycle to maintain room temperature. Thus, it would blow hot or cold, depending on if the compressor was on, and the thermostat was calling for heat. Turn the fan switch to off, and let the thermostat bring the fan on. Not working part, no comment on that.
