The air-conditioning condenser is a radiator positioned between the car’s grille and the engine-cooling radiator in which the gaseous refrigerant sheds heat and returns to a liquid state. The liquid refrigerant flows to the evaporator inside the dashboard, where it cools the cabin. Not cool enough for you? It might result from a clogged air-conditioning condenser or disabled cooling fan. A leak in the condenser will also result in a loss of refrigerant.
