I have a 93 Nissan Maxima, the car runs Ok in warm weather, but when the weather gets cold the following happens: When the engine is idling the Temperature Gauge (in the dash board) is normal and there is sufficient heat. However, when the temperature is cold (at or about freezing) and I start driving the temperature gauge slowly drops and so does the heat in the car, regardless if I have the heat on or not the temperature gauge goes down to C. This condition occurs faster when I am driving at higher speeds (e.g., highway) the temperature gauge goes down slowly to below Cold (C) and the heat goes down with it. I have replaced the thermostat and the coolant has been flushed.
