If your car heater is not removing condensation, chances are something is wrong. When your windscreen is fogged up it can be dangerous to drive due to your lack of visibility, so it needs to be fixed as soon as possible.

What causes condensation in your car?

When you get into your car on a cold morning, the heat from your body and your breath warms the air inside the car and increases the moisture levels. When the moist, warm air comes into contact with the cold glass it condenses and causes your windows to fog up.

How do I get rid of condensation in my car?

The main way to remove condensation is to crank your car’s heater up. If this doesn’t work – then chances are something is wrong with your heating unit and it will need to be repaired by your mechanic.

If your heater is at least partially working, try these tips:

  • Make sure that the hot air coming out of your vents is directed at your windscreen and windows, and turn the fan up on full.
  • You don’t want to overload your car with really hot air straight away, so start with a lower temperature and slowly turn up the heat.
  • Turn your air conditioning on, it will help to dry the air out more quickly.
  • Make sure you have your heating unit set to fresh air, and not recirculated air.

Why is my car heating not working?

A car heater can stop working for several reasons, including:

  • Your antifreeze/ water level in your radiator but might low, which could be caused by a leak in your cooling system
  • Your engine cooling system thermostat might be faulty
  • Your blower fan might have stopped working
  • You might have a blockage in your heating core that is stopping air from circulating probably into the interior of your car.

These are just a few of the common causes of heaters not working properly, its best to get your mechanic to examine it to know for sure.


Reasons your car heater won’t remove condensation

If your car heater is unable to remove condensation from the interior of your vehicle, there could be several reasons for this issue. Here are some possible causes:

  • Malfunctioning HVAC System: The heating, ventilation, and air conditioning (HVAC) system in your car plays a crucial role in removing condensation. If the HVAC system is not functioning correctly, it may not effectively dehumidify the air inside the car, leading to persistent condensation.
  • Clogged HVAC Drain: The HVAC system has a drain that removes moisture collected during the dehumidification process. If the drain becomes clogged or blocked, water may accumulate, preventing the system from effectively removing condensation.
  • Faulty Blower Motor: The blower motor is responsible for circulating air throughout the HVAC system. If the blower motor is not working correctly or operating at a reduced speed, it may not be able to distribute dry air effectively, leading to condensation issues.
  • Damaged Heater Core: The heater core is a component of the HVAC system that helps warm the air before it enters the cabin. If the heater core is damaged or leaking, it can introduce moisture into the air, exacerbating condensation problems.
  • Cabin Air Filter Issues: A dirty or clogged cabin air filter can restrict airflow and hinder the HVAC system’s ability to dehumidify the air. This can contribute to condensation buildup inside the car.


Should I get my car heater fixed?

It is important to get your car heater looked at by your mechanic ASAP, it can be extremely dangerous to drive without the ability to quickly remove condensation. At the end of the day if you don’t get it looked at and fixed it won’t go away by itself and might become worse over time.
