Do you notice that your car’s heater not circulating hot air in the car’s cabinet? If yes, then you should read this article, where we will share some simple techniques to fix a car’s heater. So, let’s get started:
1. A Blown Fuse
The car’s heater sometimes won’t function because of a blown fuse. This happens when there is a problem with the car’s climate control system. If you encounter this problem, you need to open the fuse box and remove the blown fuse. You should immediately remove the fuse because it affects the delicate electric components. If you can’t find the fuse, you should check the owner’s manual. If the fuse is causing the problem, replacing it may get the heater running.
2. A Faulty Thermostat
The thermostat is a common problem in many cars with malfunctioned car heaters. This happens when the thermostat fails to open and let coolant flow through its opening. As a result, the car will overheat, which may negatively influence the engine’s performance. Therefore, you need to replace the thermostat immediately to save yourself from huge repair costs.
3. A Bad Blower Fan
The coolant circulates through the heating system and reaches the heating core. Coolant is a mixture of water and antifreeze. When the heating system properly works, the fan at the heating core blows the heat into the car’s cabin, passing through the filters. However, if the fan stops working, the coolant won’t evaporate. Furthermore, it heats the engine causing other severe problems.
When you turn on the heater and couldn’t hear the sound of the fan from the dashboard, this indicates that the fan isn’t functional. Therefore, you need to open the dashboard, remove the heating core along with the fan, and place a new working fan.
4. A Cooling System
The cooling system consists of coolant that flows through hoses and valves throughout the heater. Furthermore, coolant plays an important role in transferring the water into the heating core. The core heats the water, and the fan distributes the air inside the vehicle’s cabin. However, when the coolant mixture is low, the cooling core won’t properly work. This disrupts the heater’s performance and prevents hot air to flow into the vehicle. You need to add coolant to the vehicle to complete the heating process to solve the problem. Also, when the coolant contains rust particles or other contaminants, the heating process disrupts. You need to replace the contaminant coolant with a new mixture in this condition.
You can save sufficient money now that you know how to solve a faulty car’s heater. Simply, identify the problems and follow the steps to solve them. The only time-consuming process would be determining the actual cause for the malfunctioned heater. Once you pinpoint the issue, you can simply replace the component and enjoy the hot air inside the cabin throughout the winter season.
