After a period of quite strong rains in the place where I live, my car began to present a fairly rare failure, it turns out that the first time that happened, walking with the car on the 15 min (for saying something), the temperature needle marked up to the stop, the climate compressor went out and drummed to lift the chest, to my surprise, the car did not present signs of being overheated, the level of the refrigerant It was fine, I did not throw water, the refrigerant does not boil, the fan was on, I have moved it three or four times after the first fault and remains the same, it is desperate because every time I finish some route I have to disconnect the battery since the fan stays on until the temperature that is marked on the board is lowered and I already stayed without battery on one occasion, what can it be?
