Did this issue start after the thermostat was replaced, or was the thermostat replaced because it had this issue? If it started after the thermostat was replaced, you probably have an air pocket in the system that is preventing the coolant from circulating. This will cause it to overheat and will also keep the heater from blowing hot air.
