Media post: Quick Fix for No Heat in Car: Easy Troubleshooting Guide

As the winter comes around, many of us will disappointingly discover that our car’s heating is not working. We get the feeling that comes with it. It can be very annoying and also concerning.

As we all know, car repairs are expensive. If you are not mechanically gifted, fixing your car’s heater can seem daunting. Modern cars are jam-packed with features. So, fixing even the smallest problem feels like you need a degree in automotive engineering.

Well, don’t worry! We will guide you with all you need to know about your car’s heating system. We will tell you all the quick fixes you can do to get your heating back on!

However, it does not have to be that way. Knowing what to look for when your heating system is acting up is half the battle. Here are the common reasons why your car’s heating might be acting up:

1.                  Broken Thermostat

Most engines come with built-in thermostats. These are crucial components for regulating temperature. And they do a good job of it too.

Unfortunately, all mechanical systems are prone to failure. And if your heating is not working, it probably is your thermostat. If your thermostat is the issue, you can simply replace it from reputable suppliers like my auto parts online.

2.                  Low Coolant or Antifreeze

You see, your car’s heating system works in pretty interesting ways. The engine coolant keeps heat away from your engine. Antifreeze, or engine coolant, is crucial for your car’s cooling system to work properly. Which, as you might imagine, makes it super hot.

When there’s enough coolant, some of it gets into the heater core as well. Then the heater core gets pretty warm. So, when the heater fan blows onto this core, you get nice warm air inside your car. Now, the problem is if there is low engine coolant, it does not reach the heater core.

Fortunately, low-engine coolant is the easiest fix. Just add more engine coolant. However, remember never to add engine coolant when the radiator coolant is hot to the touch.

3.                  Trapped Air in the System

Trapped air in the system is another common reason that might be giving you your car heating woes. Trapped air usually happens for other easily fixable issues in your car.

Things like improperly replacing engine coolant, low engine coolant, or replacing engine coolant parts can introduce excess air.

Getting the air out of your car’s heating system is pretty easy though. You can simply bleed your car’s cooling system to remove any excess air bubbles inside the system, and voila! Your car’s heating should be back up and running.

4.                  Faulty Heater Fan

Another reason your car’s heating system might not be working is because of a faulty heater fan. The heater fan does a very simple yet crucial job.

It circulates the cool or hot air into your car’s cabin. So, without it, the hot air inside your heating system is not really going anywhere. As you might imagine, that’s a problem. If no air is coming out when the heater is on, that’s a telltale sign of a fault blower motor or heater fan.

Thankfully, the heater fan is pretty simple to replace. But for this one, we recommend you take it to a mechanic. Especially if you are not familiar with working on a car, it’s the safest option.

5.                   The Heater Core is Clogged

Your heater core is one of the more robust parts in your car’s cooling system. However, in some cases it can cause your car’s heating to not work if it’s clogged.

The heater core can be clogged by debris and other materials settling in there. If this is the case, you are either looking at a full replacement or a major refurbishment.

Regardless, a clogged heater core won’t provide sufficient heat into the cabin as the heater fan blows onto it. Additionally, it can also cause uneven heating issues.

6.                  Broken Radiator

Culprit number six is a broken radiator. See, a car is a modern engineering marvel. Each component is carefully integrated to give you a fully functioning system.

The radiator is a crucial component of that system which distributes the coolant or antifreeze. Therefore, if the radiator is leaking or broken, the antifreeze is not getting dispersed properly.
