Hello. I have a problem with climate. in May I bought air conditioning and after 1 month it did not cool. Service has found a leak under the coolant tank. The air conditioning was repaired and refilled. After another month, there is no refrigerant again. I gave the car to another service and they do not see the leak. Where else could the fault be? Maybe under the car and a plastic cover? Where is the second heater? I am asking for advice.
