1. Check the blower motor. The blower motor is what actually circulates the air inside your car. If the blower motor is not working, no air will be blown out of the vents, even if the air conditioning is on. To check the blower motor, turn on the air conditioning and listen for a noise coming from the dashboard. If you don't hear anything, the blower motor may be faulty and will need to be replaced.
2. Check the cabin air filter. The cabin air filter helps to remove dust, pollen, and other allergens from the air that comes into your car. If the cabin air filter is clogged, it can restrict the airflow and prevent the air conditioning from blowing air effectively. To check the cabin air filter, open the glove box and look for a small, rectangular filter. If the filter is dirty, it should be replaced.
3. Check the evaporator core. The evaporator core is a part of the air conditioning system that helps to cool the air. If the evaporator core is clogged or damaged, it can prevent the air conditioning from blowing cold air. To check the evaporator core, look for a small, black box under the dashboard. If the evaporator core is clogged or damaged, it will need to be replaced.
4. Check the refrigerant level. The refrigerant is the gas that circulates through the air conditioning system and helps to cool the air. If the refrigerant level is low, the air conditioning will not be able to blow cold air. To check the refrigerant level, you will need to take your car to a qualified mechanic.
If you have checked all of these things and the air conditioning is still not blowing air, it is likely that there is a problem with the air conditioning system itself. You will need to take your car to a qualified mechanic to have the air conditioning system diagnosed and repaired.
