How To Use A Car Heater – Short Version
This is a condensed version. I’m assuming you’re trying to stop tricks in the car now. Activating your car’s heater is a simple three-step process. If your car is newer, you may only have one button to press. Either way, you’ll soon see how easy it is.
Modern cars have fairly sophisticated heating systems. They call them air conditioners or HVAC (heating, ventilation, air conditioning). If you have a car that is only a few years old, be aware of the ‘windshield demist’ button on the heater panel.
When Demist is pressed, the heater control module will control the heaters and give priority to cleaning the windshield and side windows.
Step 1:
Start the engine and let it idle. Driving can help speed up the warm-up process. Car heaters don’t really give off heat until the engine has warmed up a bit. A modern car warms up in about five minutes.
Warm-up time depends mainly on how cold it is outside, with older cars, cars with larger engines, and diesel engines taking the longest.
Step 2:
Locate and adjust the temperature control knob. Some vehicles have a simple shift wheel. Others have digital displays. Usually measured from low to high 28 degrees Celsius. The
luxury car has dual climate control. It’s a fancy word for her two temperature controls on the driver and passenger sides. Set both controls to the maximum setting for full heat.
Step 3:
Turn on the fan to turn on the heating system. Set the fan motor to the desired speed. Please note that heating may vary. Sometimes there is no button, but it could be a button instead. Either way, you’ll see a fan icon that is basically an “on” button. The
blower motor is a variable speed fan. Setting the fan speed too high will not regulate the temperature. It just increases the distribution of available or selected heat.
This is it. Enough knowledge to get the heating in the car working.
What Do The Different Heater Controls Do?
Here, we’ll take a closer look at each heater control, how to identify them, what they do, and when to actually use them.
We already know how to turn on a car heater and control the heat, but modern car heaters are such sophisticated pieces of kit that they are no longer called heaters. You name your air conditioner.
air conditioners are managed by our own control device (computer). Heater controls are grouped into panels and located in the center console. The
climate control unit is connected to other control units in the vehicle. They all play a role in climate control inside the cabin. Raising the
heater fan will prove to be helpful for the engine management ECU. Engine revs often increase. The air conditioning system also manages the air conditioning and can take into account the amount of sunlight hitting the car.
Knowing what all these buttons do will help you deal with all weather conditions in your car. It can handle frozen toes, extreme sun, and unpleasant outside odors.
Temperature Controls
A temperature control knob is obviously important to an effective car heating system. We were all in the car when it was too hot or too cold. It’s not a pleasant experience.
Finding the sweet spot requires adaptation, especially when body temperature changes. For this reason, temperature control buttons are perhaps the most important and commonly used on heater control panels. His
heater controls on modern cars usually include a digital display and his two buttons (one for height and one for low). Older vehicles may have colored tilt wheels. It’s effective and gives a great visual cue as to what it’s controlling. Blue represents cool colors and red represents warm colors.
Many vehicles have two temperature controls, one to adjust the driver’s seat area and one to adjust the passenger’s seat area. Some even have temperature-controlled zones for the rear seats.
What’s Blower Motor?
Without a blower (fan), the hot air wouldn’t move through the car or clean the windshield. The ventilation button is the “on button” for the entire heating system.
fans have different speed settings and as you know, faster speed doesn’t mean hotter. It just moves the air faster.
Similar to temperature controls in modern automobiles, fan controls typically have a digital display and two knobs (one for high speed and one for low speed), but simple rotary knobs are also common.
What’s Air Distribution?
Especially on chilly mornings, rainy days or dead heat, the ability to channel air is very important. Heated air can be directed using the controls on the control panel. The most common and important directions are:
- Windshield
- Side window of car
- Passenger feet
- Passenger face
- Feet and face
The air can be further directed by manually adjusting the dashboard-mounted vents. Air is induced by controlling a blend door in the heater box. And with computers now in charge of climate control, there are more and more directional options.
Airflow controls in modern automobiles are primarily occupant digital graphics. A single button to scroll through the set menu is also fairly standard.Older vehicles may have the button identified with a graphic indicating its function.

What’s Windshield Demist?
All modern air conditioning systems have a demister knob. Some models may have different names. Defroster, etc. It’s a single button, and its function is to clean the windshield and side windows in no time, without having to mess around with other controls.
Dehumidifies the air using air conditioning with pre-programmed settings. This is the correct setting for a frozen or fogged windshield. However, after it disappears, the demist setting should be turned off.
There is often a delay between pressing a button and performing an action. This is because the heater has not yet received enough heat from the engine.
What’s The Auto Setting For?
Auto setting adjusts the temperature at which the temperature is set. Some climate systems may call it differently. The
Auto button, such as comfort mode, automatically controls air conditioning, fans, and other settings to maintain the desired temperature inside the vehicle. This is the perfect setting for everyday use. Just set the temperature and press Auto.
What’s Recirculation Button Do?
Car heaters typically use outside air to heat the interior of the car. Air is taken in from the outside air outlet, passes through the cabin filter that catches bugs and dust, and passes through the heat exchanger. The heated air is distributed to the air vents inside the vehicle.
So what’s a recirculate button and why would you use it?
An air recirculation button prevents outside air from entering the cabin. Cars take a long time to warm up from a cold start, so recirculating the partially heated cabin air is the most efficient and quickest way to bring the cabin to the desired temperature.
The same applies to cabin cooling. Air conditioners cool already-chilled air, so it cools down faster. The
Air Recirculation Button is also useful during brief periods of poor outside air conditions, such as in traffic jams behind a stinking diesel engine. However, prolonged use will fog up the windows and reduce the air quality inside the car.
Two recirculating symbols are common. A circular symbol with arrows for modern cars and a car with an arrow symbol inside for older cars.
Rear Heated Window
A heated rear window is ideal for frosty weather. When switched on, heat is generated in the rear window. Heated rear windows are not technically climate control buttons, but they are usually grouped with them.
The heated rear window consumes a lot of power and is wired to turn off automatically. The workshop repair manual covers all aspects of vehicle operation, maintenance and repair, including a troubleshooting section. It’s a few bucks and contains a lot of useful information.
How do you use the heater and air conditioner?
Relying on the trim stage of your vehicle, you’ve got a manual heater, air conditioner, or an automatic weather control machine. If your machine is manual, here’s how to use it:
- Warmth: To show the heat, modify the temperature gauge from bloodless to heat. The AC may be on or off, and you can set the blower stage to your selected setting.
- Air Conditioner: To turn off the air, clearly press the AC button, which regulates the temperature to manipulate your selected temperature. Modify the blower dial to your chosen setting. Pressing the max AC button will flip the system to most cooling.
- Defrost: To turn on the defrost for defrosting your car, simply press the front defrost button on the heating and air conditioner controls, after which modify the blower and temperature to your liking.

Does the car heater work with the engine off?
No, the engine needs to be turned on. The heater does not drain the car’s battery; the fans that blow the heat do that.
The fans of the heater get power from the accessories connection of the start/ignition switch. So if the car is off or the engine of the car is off, the fan will not receive any power, so it won’t be able to work.

How to make a car heater work better?
To make your car heater work better, use the following tips
- Let your car warm up before you drive it as the car’s heater takes warm air from the engine and pouches it to the cabin. If you suddenly just turn the heater too fast, it’s more like turning on a cold oven and leaving its door open. So let your engine warm up before turning the heater on.
- Never keep the heat too high, as the heater gets warm air from the engine; you can run out of the engine if you turn the heat too quickly. Always keep it on low or medium setting until you have been driving for a long time.
- Always warm up the whole car instead of focusing on a particular area. If you keep a lower heat setting with a high fan, this will spread warm air in the whole car.

How to use a car heater in winter?
Step 1. Make sure your vehicle is in a safe, warm place.
Don’t let your vehicle be in too cold places. It should be outside in some open air, not in the garage.
Step 2. Turn on the vehicle, the engine, and defrost.
The defroster will help clear the windows, and the car will come to average temperature while the engine is warming up. Is window fogging a problem? Then you need to wait until it warms down.
Step 3. Let the engine run for 2-5 minutes.
That’s all most vehicles that are old or newer need. If it is freezing outside and your vehicle is parked in the garage or outside it is covered in snow or ice, give it a minute or two to warm up.
Step 4. Start slow and take it easy for the first 5-15 minutes.
Idling your car for long periods can be bad for your engine. What will help is to remember to start slowly and keep the gas pedal down for about 5-10 minutes when driving in cold weather. Otherwise, you could strain your engine before it can reach normal performance levels.
Step 5. Now turn on your car’s heater at a medium speed, not too high, as it will damage your engine.
