About car air vents:

car air conditioningModern air conditioning systems usually have several air vents which distribute air from the air conditioning system and throughout the vehicle.

Functioning air vents are crucial to your vehicle’s ventilation/air conditioning (AC) system, particularly on hot or cold days. If these vents stop working or have reduced airflow, your air-conditioning system will not work or will have reduced performance. This limits the control you have over your car’s temperature.

What causes air vent issues in cars?

There are several common causes for malfunctioning air vents. These include:

  • A blown fuse – Your vehicle’s ventilation relies on a small fuse to function properly. If the fuse is blown, the circuit will be cut, causing the vents to stop working. In this case, you will need to have the fuse replaced.
  • Broken hose – There are several small hoses used to make your ventilation system work. If any of these hoses are punctured or ripped, your air vents may not produce air as expected.
  • Failing motor – There is a small motor that sends air through the vents in your car. Over time, this motor can become damaged and affect the flow of air to your vehicle’s cabin.
  • Air duct blockages – The air ducts are the channels that carry the air from the blower motor to the vents. If these ducts become blocked or damaged, the airflow can be restricted.
  • Blockages in the air vent hoses – such as small glass fragments from a previously broken windscreen or window, or children putting items into the vents can reduce or block airflow.
  • Blocked Cabin Filter – A cabin filter is part of the vehicle’s ventilation/air conditioning (A/C) system. If it gets blocked it can significantly reduce airflow into the vehicle’s cabin. This will decrease the air conditioning (AC) systems effectiveness and can increase cabin air temperature (on hot days), meaning the engine and air conditioning have to work harder to try to heat or cool the cabin. This uses more engine power to drive the vehicle’s air conditioning and reduces the horsepower available to power the vehicle’s wheels. Another direct effect of a blocked / dirty cabin filter is that increased air pollutants such as pollen and dust may enter the cabin, which is very bad for your general health and especially bad for allergy sufferers.
  • Leaking vacuum lines – The vacuum lines in the car’s AC system control various functions, such as the vent doors and the blend doors. If these lines develop leaks, they can prevent the vents from opening and closing properly, resulting in reduced airflow.
