Cars Q&A

If you are using the heater that comes with the car, that is, by turning a knob on the dashboard, most certainly you are in no danger of anything catching fire. In most cars, the heater is just an air vent that is routed somewhere around the engine block to gather the heat from the engine to warm up the air coming in. If you are plugging some other heater, for example, to the cigarette lighter and an invertor etc., you might be asking for trouble!
