Q: 2012 qx56 AC not blowing cold or even cool air.

asked by on

AC not blowing cold air

Hello. The air conditioner depends on refrigerant to cool the air circulating through the vehicle. If the vehicle is low on refrigerant, the system is not able to cool the air blowing into the cabin. It is similar to the radiator and cooling the engine, except your air conditioner’s evaporator works with a different fluid and is designed to cool faster. You can check the refrigerant at home, as long as you only deal with the low pressure side. You can use at home charging kits to fill the low refrigerant, but it is recommended that you have someone trained and certified work on the air conditioning, due to the toxicity of the refrigerant. If the refrigerant is not low, then you have a clog or other type of pressure issue in the air conditioning system, and further inspection will be needed. For more help, contact our service department to schedule an appointment.
