If ac not blowing air

  1. Check the Blower Motor: Air is forced through the vents by the blower motor, so make sure it’s working properly. You won’t feel any air if it’s not working. In order to hear any strange sounds coming from the vents, turn on the air conditioning. If you don’t hear anything, the blower motor itself might be malfunctioning.
  2. Examine the Fuse: A fuse often protects the blower motor. The fuse must not be blown in order for the motor to operate. Locate the fuse box in your car’s manual, then check the AC or blower motor fuse. Replace it with a new one of the same rating if it has blown.
  3. Check the cabin air filter: A filthy or clogged cabin air filter might prevent airflow and give the impression that the AC is not functioning properly. The cabin air filter can be found in your car’s manual; if it’s dusty or clogged, replace it.
  4. Verify for Refrigerant Leaks: If your AC system has a leak and is running low on refrigerant, it may not be blowing chilly air. The AC compressor may also fail to operate due to low refrigerant levels. Look under the car for any indications of oil or refrigerant leaks, and if you discover any, have the leak professionally fixed.
  5. Check the AC Controls: Verify that the AC controls on your dashboard are in the right position. Make sure the temperature is set to cool, the mode is set to direct air to the vents, and the fan speed is increased.
  6. Examine the Blower Motor Resistor: The blower motor resistor, which some cars have, regulates the fan speeds. You can lose all or some of the fan speeds if this component malfunctions. Locate the resistor in your car’s manual and make sure it’s working properly.
  7. Check for Electrical Issues: Electrical issues like defective switches or wiring might occasionally stop the air conditioner from blowing. Look for any obvious damage to the wiring and switches, and if necessary, get the help of a technician or electrician to identify and fix any electrical problems.
  8. Have a Professional Inspection Performed: If after checking the aforementioned parts the AC is still not blowing air, it is recommended to have the system inspected by a qualified mechanic. They are equipped with the knowledge and know-how to identify and fix more complicated AC problems, like a broken compressor or evaporator.
