Depending on how cold it gets it can be bad.
a bad thermostat or miswire of the low voltage wiring or a bad heating relay stuck in the heating mode.

Because that is its job! A thermostat is a device that measures the temperature of a given space or volume, and turns heating / cooling devices on and off accordingly. The thermostat in your house is designed to turn the heating off when the house is warm and turn it on when the house is cold. The thermostat in your car turns the radiator fan on when the oil / water temperature increases to a level that could be damaging to the engine (if you are stuck in traffic for example)
A bad or misadjusted fan limit switch is the first thing I would look for.
