What can cause your car’s air conditioning to stop working?
Having your car’s air conditioning system stop working can be very inconvenient, especially on hot, summer days or cold winter foggy or frosty days or nights.
Your car’s air conditioning system is probably one of its most overlooked components. That is, until you need it. The air conditioning system consists of many different parts which work together to create cold air. Problems with any of these parts can lead to issues such as there be no cold air or no air at all.
Below are some of the most common reasons for air conditioning not working:
- Clogged cabin air filter – The cabin air filter cleans the air as it enters your car via the heater and air conditioning system. Over time, it can become blocked with debris and contaminants. This can limit the amount of air which reaches the interior. A blocked cabin air filter can also cause a strange, unpleasant smell to come from your car’s vents.

- Leaks in the air conditioning system – Your car’s air conditioning system contains a refrigerant which allows for the cooling of air. A leak in the system can cause the refrigerant to leave, thus preventing the air conditioning from working correctly. If your air conditioning system is only blowing warm air, the problem may be due to a leak in the o-rings, seals, hoses or other components.
- Malfunctioning blower motor – The blower motor sends air into your car’s interior. Over time, the blower motor can fail. This will lead to no hot or cold air entering your car. Sometimes, the blower motor will fail due to a bad relay, blown fuse or similar electrical fault. In these cases, the motor will not be replaced but the electrical components will.
- Malfunctioning AC compressor – The compressor is one of the most crucial components in your car’s AC system. It is responsible for pressurising the AC system and allowing the refrigerant to flow properly. Problems with the air conditioning compressor can lead to warm air flowing through the vents
- Damaged AC condenser – The air conditioning condenser is a device which converts the refrigerant from a gas to a liquid. This allows it to flow through the air conditioning system. Problems with the condenser can reduce the amount of cold air which reaches the cabin of your car.
Symptoms of a malfunctioning AC system:
- The car is only blowing warm air – This can be caused by a lack of refrigerant or leaks in the air conditioning system. It can also be caused by a failing compressor or condenser or jammed or broken valves or linkages.
- There is no air being sent through to the cabin when the air conditioning or heater is turned on – This can be caused by a blockage in the cabin air filter or problems with the air blower motor.
- There is very little cold air coming through the vents – This can be caused by a build-up of mould inside the evaporator core, or a blockage in the system.
