Hello. the forum is always there to help. I'm counting on you. Air conditioning system after the service. gas is. Tightness tests are good. I have a strange situation. Whether in the machine or I give manual control of the air conditioning temperature in the back for the 2nd row of seats, I have cool air. The climate works fine. It is worse at the front. The passenger is worse than the back. It is poorly cooling the driver's area. What's the problem?
