I arrived with the problem "the air conditioner is not working", the master opened the hood, screwed on the hoses of the freon injection device, after which he said that I had a low-pressure nozzle of the compressor to the radiator and there was no point in doing anything. I was charged 5,000 rubles for such a "diagnosis".
After that, I asked how much the repair would cost.
They said that the repair would cost 15,000 rubles. At the same time, a new tube (along with gaskets) on the market cost me 3,500 rubles and it is held on two nuts. I changed the tube myself, refueled the system for 1,500 rubles, and the problem of the "non-working" air conditioner, with which I arrived, turned out to be not in the pipe at all.
This is the diagnosis for 5 thousand.
A month ago, I changed the oil in the air conditioner compressor, the craftsmen seem to be smart, everything was quickly disassembled and assembled, but when dismantling the compressor, they dropped it from a height of 2 meters and bent the iron belt clutch. Of course, everything was fixed, but the sediment remained, and the prices are certainly not cheap, 5K for oil change, refueling and replacing the bearing on a 1997 Nissan is still expensive.
