Hot summer day and you need your a/c blowing in your car and the vents are only blowing warm? Have your Freon levels checked.
When the air conditioning no longer blows cool, the a/c system needs to be recharged. First you will need your system inspected. Most of the time cars are low in Freon. There could be a small leak, or you may need your system recharged. The technician will determine the correct Freon necessary for your vehicle.
