This question applies to all cars in general. When you first start driving a car with a cold engine, the car only blows cool air even when the temp. setting is on hot. Does this mean that the heat we get is from the heat of the engine?

almost all car heaters get the heat that they put out from the engine coolant. When the engine is cold there is no heat for the system to use... there are a few systems that can use other sources for the heat source until the engine warms up but they seem to be mostly in commercial trucks and the like.

When you first turn on the car when it's cold, you'll notice the temp. gauge in the instrument panel is at C or whatever the cold symbol is for your car. As the car is running or as you drive, the engine gets warmed up, the temp gauge moves towards the middle, and that's where the heat comes from.

The coolant runs through a smaller version of a radiator called a heater core. It's located behind the dash on the passenger side. The fan circulates the air through it.

Where do you think the heat comes from?
