Common Causes & How To Turn On Heat In Car?

Currently, car manufacturers are always trying to give users the best experience. The company always develops each design, such as heating, air filtration, or entertainment, to ensure modern and convenient criteria.

However, sometimes that development will give users specific difficulties during use. A typical example is the car heating system. The following article will guide you on how to turn on heat in car efficiently and quickly.

Heating Systems And Their Working Principle

Heating systems, also known as heaters, are installed directly on cars. The system is located in the vehicle’s air conditioning instrument cluster with temperature balancing between the two environments. Usually, the heating system will do its best in cold and snowy weather patterns.

Currently, each car model will be fitted with a different heating system: shape, capacity, or temperature range. However, the principle of operation of most heaters is the same.

The car’s cabin will heat up when starting the heating system as the engine coolant heats up. The coolant will absorb heat and warm up the engine. Then it will be transferred to the heatsink – the heating core. The heating core will transmit hot air through the car’s exhaust fan system.

Usually, it will take about 5-10 minutes to reach the right temperature. So, if the time is longer than 15 minutes, your car is most likely having a heating problem. You can quickly identify through the heating time or the car’s temperature gauge. Drivers should refer to the “car temperature gauge goes up and down while driving” to understand car meters better.

Many people still wonder how to start the heating system for their car. You can refer to how to turn on the heating below.

How To Turn On Heat In Car
In general, to turn on the car heating system, you need to perform the following 3 general steps:

  • Step 1: Engine on
  • Step 2: Set the desired temperature
  • Step 3: Turn on the fan speed

However, in order to perfect the healing process, you need to learn and delve into each vehicle type or design type. Here are the detailed steps to enable the driver to activate the heating after 5 minutes:

Step 1: Start the engine so that it is idling.

That way, the driver can assist with a quicker start-up. Warm-up time depends mainly on the difference between the environment inside and outside the vehicle. For vehicles with large engines or diesel engines, warming up may take longer than 5 minutes.

Step 2: Locate and adjust the temperature calibration button.

With some cars, the control knob may be a gear knob, and others will be a digital display. Usually, the temperature will be calculated in degrees Celsius from low to high, and the maximum is 28 degrees Celsius.

In particular, for some modern cars, the heating system will be designed in a dual form. At that time, both the driver and the passenger can manually adjust the temperature at will. This provides a great user experience. For full heat, you need to move both controls to the maximum setting.

Step 3: Proceed to turn on the heating system by turning on the fan.

You need to adjust the fan motor to your desired speed. Depending on the vehicle, the adjustment button will be in the form of a button or a knob. However, you can still change quickly based on the fan icon on the control panel.

For some cases when you have started the heating, but it is not heating up as expected, you need to find out the cause of the failure of the heating system. You can refer to some of the problems that cause the heater to fail below:

Some Causes Of Heating System Failure

The thermostat is broken

This is a relatively common cause of heating system failure. Because it is a worn-out part, the capacity decreases after a period of use.

According to the principle of operation, the thermostat always allows cooling water to flow through the engine. It will make it difficult for the engine to warm up in cold temperatures. If the thermostat fails, your car will have an overheating problem, which will affect the quality of the heating system.

Dirt on the cooling system

Dirt on the cooling system is a common condition for many drivers. If dust clogs the heater core, that will be why hot air is not being blown into the car. To fix it, you need to rinse several times to push all the dirt and buildup out of the heater core.

Blower fan is broken

The following reason why the heating system is not working properly could be a damaged blower fan. If the fan fails, it won’t be able to push air from the heater core into the car’s compartment. It would help if you went to the service center immediately to replace the new fan.

Some Frequently Asked Questions

What is the heat button in a car?

What is the heat button in a car
The heat button on the car is also known as the recirculation button. It plays a vital role in generating heat for your car. The heat button recirculates the air to keep your car cooler when the A/C is on.

Why is my car blowing cold air when the heat is on?

You can refer to some of the reasons below:

  • No air
  • Cold air escaping from the heating system
  • Faulty thermostat
  • Low coolant level
  • Heater core malfunction
  • The heating controller and mixing door have problems

Why is the heat in my car not turning on?

Some reasons why your car won’t turn on the heating:

  • Low antifreeze in radiator due to a cooling system leak
  • Thermostats are inefficient due to the long usage time.
  • The blower system is broken.

Conclusion

Hopefully, the article will help you quickly start your car’s heating system. On average, to get the desired heat level, you will need 5 to 10 minutes.

Therefore, if after 15 minutes the system still has not reached the desired temperature, your heating system is most likely to have a problem. You need to immediately go to the nearest service center to repair the heater.
