If your car heater works intermittently, it may be due to clogged hoses and radiators, low coolant levels, or blocked air vents. In this article we’ll discuss these issues and explain what you can do to troubleshoot the problem.
Why Does My Car Heater Work Intermittently?
Your car’s heater relies on a few key components and a regular flow of air from the engine to function correctly. If any of these parts are not working correctly, your heater will either stop functioning completely or work only intermittently. The most common causes for intermittent heating include:
Clogged Hoses or Radiators
Clogged hoses and radiators can prevent the hot air generated by the engine from reaching your car’s heating system. As such, this can cause an inconsistent flow of hot air into the cabin and reduce its effectiveness as a result. Additionally, if there is dirt or debris inside one of your radiator tubes it also has the potential to block hot air from entering your vehicle’s ventilation system. To determine if this is causing your intermittent heating issue you should inspect both the hoses and radiators for signs of blockage or dirt build up.

Low Coolant Levels
Low coolant levels can also cause your car heater to work intermittently. This is because your vehicle’s cooling system needs an optimal level of coolant to properly regulate the temperature of its engine and ensure that the hot air it generates is being distributed throughout the cabin as intended. To check your vehicle’s coolant levels you should inspect both the radiator and overflow reservoir for any signs of leaks or low fluid levels.
Blocked Air Vents
Blocked air vents can also prevent hot air from entering your car’s ventilation system, resulting in intermittent heating issues. To determine if this is causing your problem you should inspect all of your cars interior and exterior vents for signs of dirt, debris or obstructions that may be preventing airflow into the cabin.
How to Fix an Intermittent Car Heater Problem
Once you have determined what is causing your intermittent heater issue you can begin taking steps to rectify it:
Check the Hoses, Radiators and Coolant Levels
If either of these components are blocked or have low fluid levels then it could be causing a disruption in hot air reaching your cabin resulting in your car’s heater working intermittently. To check the condition of these components you should inspect the hoses and radiators for any dirt or debris build up and make sure that coolant levels are at their optimal levels.
Unblock Air Vents
If there is an obstruction blocking your car’s air vents then it could be preventing hot air from entering the cabin, resulting in intermittent heating issues. To rectify this issue you should inspect all of your vehicle’s interior and exterior vents for any obstructions that may be preventing airflow into the cabin and take steps to remove them if necessary.
Intermittent heating problems can be caused by a number of issues with your car, ranging from clogged hoses or radiators to low coolant levels or blocked air vents. If you’re experiencing an intermittent heater issue in your car then by following this article’s troubleshooting advice you can identify what is causing it and take steps to resolve it quickly and effectively.
