Today's modern car models are fully equipped with a heating mode on the car for winter days. However, drivers often confuse car heating with air conditioning. Therefore, they often do not turn on the heating mode in the car, but close the car door to reduce heat loss and save fuel. But in fact, this heating mode is operated based on the amount of heat that the engine generates when operating. People have taken advantage of them and warmed up the space inside the car compartment, so it does not consume much fuel. So, how to turn on heater in car? Find out with CouponUpto in the article below.
Working Principle Of Car Heating Mode
The working principle of a heater in a car is to take the heat emitted from the car engine through the operation of the coolant and the cooling system. For car heating mode, the water pump will play the role of pushing the coolant through the cooling system. Here there is a fireplace core that will convert hot air and eventually warm the interior space. The heater takes heat from the engine, so it takes time for the engine to warm up. So the driver can start and wait for the engine to warm up a few minutes before to feel the effect of the heating mode.
How To Turn On Heater On Car?
Heating systems (or air/temperature control systems) are quite diverse on modern car models. Therefore, not all drivers know how to turn on heater on car.
Step 1: The first thing you need to do is to press the windshield defrosting button so that the car system controls the heating system to work to dissolve the fog on the windshield, window glass on both sides of the front seats on (for cold and foggy days).
Step 2: Next, the driver starts the engine of the car, which will make the temperature rise in the cabin. Normally, the heating system does not release heat as soon as the windshield defrost button is pressed, but it will take a few minutes for the car engine to warm up. If the outdoor temperature is cold, the car has been used for a long time, the engine is large, or the vehicle runs on diesel fuel, the heating mode usually takes longer to take effect.
Step 3: Set car temperature. You can adjust the desired temperature through the digital display of the temperature in your car. Many high-end car models are also equipped with two temperature control knobs for the front and rear seats.
In addition, users can also start the car heating mode by turning on the fan and adjusting it to the desired speed. Depending on the model, the blower can be easily turned on by pressing a button or using a knob marked with the fan symbol.
Why Is The Car Heater Not Working?
The causes usually stem from faulty parts in the engine. Therefore, when the heating mode is not working, the driver can easily find out and fix the common errors below.
Faulty thermostat
This is a common cause of the cabin not warming up when the heater is on. A faulty or broken thermostat can also affect the engine's cooling system.
Low coolant
Low coolant (antifreeze) will not reach the heater core and as a result the passenger compartment is not heated. This can happen when the car engine is overloaded, overheated, or the coolant is not replenished regularly.
Defective Heater Fan
The heater fan plays the role of blowing hot air into the passenger compartment. This part when broken or has an electrical problem is also the reason why the heating mode on the car doesn't work.
Faulty Fan Motor Resistor
This situation occurs when the blower cannot adjust the speed of blowing hot air into the car cabin or even completely prevent this air from entering the passenger compartment.
Heating Core is Clogged
Although this is a rarer occurrence than the above failures, the heating core can become clogged when debris enters the cooling system. To fix this problem, the driver needs to clean or replace the heating core.
Radiator Leak
A radiator leak will prevent the coolant from reaching the heating core or even damage the car engine.
Faulty HVAC Control
Faulty HVAC controls are one of the most common causes of car heating not working. The display screen is faulty or the knobs and buttons are broken or damaged, leading to incorrect operation and causing the cabin to not be heated.
Faulty Power Cord or Blown Fuse
Broken wires or faulty fuses will prevent the car's heating mode from working when the driver pushes the buttons to turn on the system.
Note When Using Car Heating Mode
Drivers should regularly check the coolant level and add if necessary, promptly detect leaks to ensure stable operation of the heating system. In addition, the heating mode needs time to warm up the cabin, so the driver should not increase or adjust the temperature too much compared to the outside when starting the car.
In particular, the driver can use the "air recirculation" feature to get the air inside the car to warm up, which will help reach the desired temperature faster and avoid unpleasant odors from the outside environment. Car owners should also regularly get their cars to the service workshop to maintain the heating mode on the car, to ensure that the engine is always running smoothly, providing maximum comfort for the user.
Conclusion
Car heating mode will be extremely useful for drivers on cold winter days. However, users need to know how to use the heating system to bring high efficiency as well as save fuel. With the above guide about heating systems and how to turn on heater on car, we hope you will take full advantage of their features to provide comfort when using.
