Why is my car heater blowing cold air?
The heat is then transferred to the vehicle’s internal through a blowing fan. It is not surprising for the heating system to take time until it starts blowing warm air to the vehicle as it takes some time for the engine to warm up and, therefore, increase the temperature of the coolant fluid. What are the causes of a car heater blowing cold air?
When does your car run hot or cold?
If you are like most drivers, our guess would be almost never. Most drivers look at their temperature gauge so rarely that many vehicle manufacturers don’t even include temperature gauges any more but just lights that will come on if your car is either extremely cold or extremely hot.
Can a car heater be unreliable in the winter?
Unreliable car heaters can make the cold winter months practically unbearable. Several things can potentially go wrong with automotive heaters because, much like a home heating system, there are many components working together to heat your car. If one or more of these issues is present, your vehicle may blow out cool air rather than heat:
What should the temperature of a car heater be?
Some vehicle manufacturers boast their heaters will do 135F-155F (57C-68C) which would make things very toasty indeed. If the temperature is OK, and the cabin of the vehicle is still not getting warm, it might be down to a problem with the fan blower or the ductwork under the dashboard.

How is heat generated in a car heater?
The basic principle of how heat is generated in most vehicles is very simple. When the engine warms up, the coolant around it absorbs some heat and increases its temperature. The heated coolant then goes through a special valve (i.e., the thermostat) to reach the radiator, which reduces its temperature.
What do you need to have a heater in your car?
To have heat, you need: enough water in your engine; a working thermostat, a working heater and heater controls a cooling system that doesn’t leak.
A car heating system blowing cold air can be due to a faulty thermostat, low coolant fluid level, malfunctioning heater core, a leaking cooling system, or problems with heating controls and blend door.
How much fuel does an Espar heater use?
This heater can run for 24 hours on one gallon of diesel, which is excellent, in terms of consumption.
