Air works great but now that cold weather is here I have no heat. Could it be the thermostat or the temp sensor switch?

    Start by checking engine temperature - see if it gets actually hot. Check the inlet and outlet hoses of the heater core - scalding hot, or just warm? If they are both scalding hot, then you are looking at a temperature control issue inside the car.
