If the outside temperature is high and we turn on the air conditioning or climate control set to 24 degrees, but the air coming out inside the cabin is hot, it may be due to…

Correct answer: a refrigerant gas leak in the system.

Air conditioning cools using a refrigerant gas that circulates through a closed system. If there is a leak, the system has too little gas and provides little or no cooling, even if you set it to 24 degrees. Take the car to a repair shop to have the leak located and the refrigerant recharged. The lubrication system lubricates the engine and has nothing to do with the air in the passenger compartment. In the image, the climate control shows 24 degrees with the air conditioning on, and hot air comes out of the vents.
