How to Turn on the Heater in Your Car? Have you ever been driving on a cold winter’s morning or late at night, only to be frustrated by the frigid temperatures in your car? No worries! Taking control of your comfort is easy when you know how to turn on the heater in your vehicle.
Whether it’s natural gas, electric heat, or just plain old manual cranking that you need for warmth; we’re here to give you all the tips and tricks needed so you can stay cozy no matter what Mother Nature throws your way. So get ready, let’s learn how to turn up the heat in style!
3 Steps To Turn on the Heater in Your Car
Step 1: Turn on your car’s engine.
Regardless of your car’s ignition type, start the engine to generate heat that will be pushed through the vents when you activate the heater.
It usually takes about 5 minutes for the engine to warm up, and you can either begin driving or allow the car to idle for a few minutes.
Step 2: Adjust the temperature dial to adjust the heat level
The temperature dial is typically located in the center console and has blue and red coloring. Blue indicates cold air and red indicates hot, so adjust your dial towards the red (usually to the right).
The further you turn or push the dial to the right, the higher the heat level will be. If your vehicle has a digital display, simply select the temperature control icon and increase the heat by pressing the + button on the screen.
Step 3: Adjust the fan control to your preferred fan speed
Locate the fan speed control, typically placed directly next to or beneath the temperature control, and adjust the dial to the right until reaching a comfortable speed.
Keep in mind that higher fan speed control results in faster car heating. Additionally, you can direct the heat to specific areas by adjusting the airflow dial, usually located adjacent to the fan speed control.

- Dashboard vents
- Windshield and face vents
- Face and feet vents
And there you have it. Now, you know the three easy steps to turn on the heater in your car. Keep in mind that it take up to 5 minutes for car’s engine to generate heat, so be patient. And if you’re still having trouble, don’t hesitate to get it checked out by a professional.
Troubleshooting Car Heater Problems
Check if your heater vents are closed.
On some vehicles, you will need to manually open the vents in order for them to blow hot air.
- Make sure your coolant levels are full and that there aren’t any leaks. Low coolant levels can cause your car heater not to work correctly.
- If your fan speed is set too low, then it won’t push the hot air out of the vents as quickly.
- Check for any blockages in the heater core which may be preventing air from flowing through properly.
- If you’ve tried all of these tips and are still having trouble, then it might be time to take your car into a technician for further diagnosis and repairs.
Check your car’s coolant level.
Low coolant levels can prevent your car’s heating system from functioning properly. Make sure to check your car’s manual for the exact type and amount of coolant needed, then top it up if necessary.
Have your thermostat inspected.
If your car’s heater is not blowing hot air, it could be due to an issue with the thermostat. To fix this, you’ll need to have a qualified auto technician inspect and replace the thermostat as necessary. This should help ensure that your car’s heating system functions properly.
Be sure to keep up with routine maintenance on your car’s cooling and heating system. This can help ensure that everything is working properly and that you don’t run into any issues in the future.
How to manually turn on the car heater?
If your car does not have an automatic heating system, you can manually turn on the heater by following these steps:
- Locate the manual heater knob or switch in your car’s cabin and turn it to the “on” position.
- Adjust the temperature dial to set how hot you want the air to be.
- Adjust the fan control to choose which speed you want the air to be circulated at.
- Wait for the car’s engine to warm up and heat up your car’s cabin space before getting in and enjoying that cozy warmth!
And there you have it – easy steps to manually turn on your car’s heater! Remember to keep up with routine maintenance to ensure that your car’s heating and cooling system works properly. And don’t hesitate to contact a professional if you have any further questions or troubleshooting needs.
The Common Issues with Car Heaters
There are several reasons why your car heater might not be working as it should. Some common issues and their solutions include:
- Low coolant level: A low coolant level can prevent the heater core from receiving enough hot coolant, resulting in insufficient heat. Check the coolant level and top it off if necessary.
- Malfunctioning thermostat: A stuck-open thermostat can prevent the engine from reaching its optimal operating temperature, affecting the heater’s performance. In this case, the thermostat needs to be replaced.
- Clogged heater core: Over time, debris and contaminants can accumulate in the heater core, restricting the flow of hot coolant. A clogged heater core will need to be flushed or replaced.
- Faulty heater control valve: A malfunctioning heater control valve can prevent the flow of hot coolant to the heater core. The valve may need to be adjusted, repaired, or replaced.
- Blower motor issues: If the blower motor is not functioning correctly, it may fail to blow air over the heater core. This can be caused by a blown fuse, a faulty motor, or a damaged resistor.
What Does the “Recirculation” Button Do?
The “Recirculation” button, often represented by a circular arrow icon, allows you to choose between fresh air from outside or recirculated air from inside the cabin.
When the recirculation mode is activated, the heating system will use the air inside the car, which is already somewhat warm, resulting in faster heating.
However, it’s essential to switch back to fresh air mode after a while to ensure proper ventilation and prevent fogging of the windows.
FAQ Turn on the Heater
Where is the heater switch in a car?
The heater switch is usually located in the center console of your vehicle. It may be a dial with red and blue markings or a digital display with an icon for temperature control.
Typically, the blower motor is located under the hood along the engine’s firewall or behind the glove box. If you can’t find the resistor switch near the blower motor, check behind the panel that holds the heater knobs.
Do you turn on AC for heater in car?
No, you do not need to turn on your car’s air conditioning system for the heater to work. The AC and the heater are two separate systems that operate independently of each other. Simply adjust the temperature control to a warmer setting in order to activate your car’s heating system.
Should the heater be on auto or on?
The heater should be on auto when you’re using it to heat the cabin of your vehicle. This setting will allow the car’s computer system to automatically adjust the temperature inside the car based on external temperatures and your preferences. If you’d like to manually control the temperature, then select the “on” setting instead.
How does heater work in car?
The car heater uses the engine’s hot coolant to warm air that is then pushed through the vents by a fan. The driver can control the temperature of the heated air using a thermostat and fan speed controller.
When the thermostat is adjusted to a higher setting, more hot coolant flows into the heater core which results in hotter air being blown out of the vents. The fan speed controller is used to adjust the rate at which the hot air is pushed through the vents.
Knowing how to turn on the heater in your car is essential for anyone who wants to stay cool even during the coldest winter months. With a few easy steps, you can quickly take control of the climate inside your vehicle. From natural gas heaters that require no cranking to electric heaters that are more manageable and less costly, our guide has everything you need to know about staying cozy and warming up your car in no time.
