[Quick & Easy Steps] How To Turn On Heater In Car?

How To Turn On Heater In Car
  • If your car’s heater isn’t working, the first thing you should do is check the thermostat. If it’s set too low, the heat won’t come on. If it’s set too high, the heat will come on but it won’t be as strong as it could be. The next thing to check is the radiator. Make sure there is enough coolant in it. If not, add more until it reaches the full line.
  • If your car has an automatic climate control system, make sure it is turned on and set to “heat.” If you have manual controls, turn the knob to “hot” or to the right.
  • If your car has heated seats, it may not work because the switch is turned off. Check the switch and turn it on if it’s in the off position.

What Is The Manual Way to Turn On The Car Heater?

In some older models of cars, you do not have the option of an automatic climate control system. Some of you may prefer manual operation so you can adjust the car’s temperature as your body temperature changes. Alternatively, if you don’t have or don’t wish to use an automatic heater and cooler, you can manually turn on the car heater.

We are back to the simple three steps from before. Let your vehicle warm up by starting the engine and letting it idle for a few minutes. You can turn the heat up by toggling the temperature button, spinning the wheel or dial, or pressing the increase button on your digital display. When you turn on the fan and set the fan speed, warm air will start blowing out and distributing throughout the cabin.

How Do the Different Heater Controls Work?

How Do the Different Heater Controls Work?

Often, vehicle heating system controls can appear complicated and intense. The functionality of your heating controls is actually quite simple once you know what each button or dial does.

1. Temperature Controls

Typically, the temperature controls are easily spotted. Many vehicles, particularly older models, have color coding: turn towards blue for cold air and red for hot air. However, cars with digital displays may skip the color coding and simply show you the actual temperature the system is set at.

Also, your vehicle might have dual temperature controls that can be customized differently for the driver’s and passenger’s sides. Adjust the temperature controls until you reach the desired temperature.

2. Controls for Fan Speed

Besides the temperature toggles, fan speed controls may be among the most important heater controls. You can adjust the fan speed of the blower motor with the fan speed controls. The faster the speed, the faster the air moves around the cabin.

3. Air Direction

Directly controlling the direction of airflow inside a vehicle is air direction control. The controls allow you to choose where the air will blow out from, and there are typically a few choices:

  • Windshield vents
  • Dashboard/face vents
  • Feet vents
  • Face and feet vents
  • Windshield and feet vents

You’ll usually see an image of a person with arrows pointing in different directions. Choose your preferred air-blowing option.

4. The Recirculation Button

The car heater system draws in outside air, circulates it through the heat exchanger, and distributes it throughout the interior cabin. The recirculation button typically depicts a curved arrow and halts the heater system’s circulation of outside air, instead of circulating the air in the cabin.

This button is particularly useful when first warming up your vehicle because it will be quicker to heat up partially warm air than the cold outside air. You may also wish to employ the recirculation button when the outside air quality is poor.

When I Turn On the Heat, My Car Blows Cold Air

Your thermostat may be malfunctioning if your car blows cold air when your heat is on. Ensure that your vehicle is diagnosed and repaired by a mechanic who is certified in HVAC work.

How Should I Turn On the Car Heater?

Start your engine and let it idle for five to ten minutes before turning on your car heater. It will also be helpful to employ the recirculation button when you turn the heater on so the heating system stops pulling in outside air and instead recirculates the cabin air.


Turning on your car’s heater is a relatively simple process and one that you can do in just a few minutes. By following these steps, you’ll be able to warm up your car quickly and get on with your day. We hope this article has helped you learn How To Turn On Heater In Car.
