A/C in vehicle not blowing cold air, it starts with slowly reduction of cold air over time until the air that comes out the ac vents is warm. This kind of problem usually indicates slow refrigerant leak or a clogged condenser.
Refrigerant serves as the life blood of the a/c system. The refrigerant is the one that carries heat coming from your vehicle compartments, where the passenger is located, out to the surroundings so that the compartment becomes cold and provides comfort to the passengers. When the refrigerant is leaking, as in this problems case it slowly leaking, it will result to a steady reduction of cold air that comes out the a/c vents until the ac in your vehicle is not blowing cold air but instead ac blows hot air.
On the other hand, when the condenser is clogged the air that comes out the vents will also not cold. The condenser is an a/c system component, mounted in front of your vehicle with the radiator, which removes the heat carries by the refrigerant from your vehicle passenger compartment. Overtime the condenser can become clogged with dirt or debris that may results in the reduction of cold air produced by the a/c system but this problem will only contributes why the a/c system is not blowing cold air that causes by slowly leaking refrigerant.
