Car owners must get their vehicles ready for the harsh weather that the winter months offer, which includes cold and ice. This includes inspecting the heater in your car before venturing outside in the cold. Here are some actions you can do if the heater in your car isn’t working.

How the Heating System in the Car Operates

The air that is blown into the car’s cabin is heated by the heater. When you start the automobile, however, the heater does not immediately begin to blow hot air. It is explained that the longer it takes for your car to heat up and keep you warm, the colder the outside temperature is. The thermostat, a temperature-sensitive valve situated in the cooling system between the engine and the radiator, is mostly to blame for this.

In general, engines operate best between 90 and 104 degrees Celsius; at lower temperatures, they run less effectively and produce more pollutants. The thermostat closes to prevent coolant within the engine from passing through the whole cooling system in order to get there as quickly as feasible. The thermostat opens once the engine has warmed up sufficiently. To keep you warm, the now-warm coolant circulates into the heater core.

Typical Car Heater Issues
90% of the time, issues with car heaters are caused by one of the following:

• Possible flaws in the heater switching system.
• The heater core’s airflow may be constrained if the cabin air filter is clogged.
• It’s possible that the thermostat valve is malfunctioning.
• Perhaps the heater core is clogged.
• What to Do If Your Car Heater Doesn’t Work
• You must identify the cause of the issue before you can resolve it. Before sending your automobile to a mechanic, you can attempt a few things on your own. Try these things:

Whether the heater in your car isn’t working properly, put the blower up to the highest level to see if the heat is turning on. If that’s not the issue, see if the heat settings may be changed. Move the heater settings around in your car until you find a comfortable temperature.

In the event that this is unsuccessful, it is time to investigate potential engine problems. Make that there are no fluid leaks, hose breaks, or loose connections. It’s crucial to make sure the exhaust manifold is not hot or damp to the touch. If the engine compartment appears to be in good shape, you could want a replacement cabin air filter.

You may have an engine obstruction issue if the heater in your car is no longer pumping cold air but is still blowing warm air. You can try directing a garden hose onto the exhaust manifold to check it out. Any debris that might be obstructing the heater core can be removed using this. You can also solve this issue by starting your automobile and letting it run for around 15 minutes.

What to Do If the Heater in Your Car Is Still Not Working

It might be prudent to take your car to a pro if everything you’ve tried so far has failed. There is a possibility that the heater core has to be replaced if the issue isn’t under the hood.
