I knew it was the compressor. For some reason, the compressor first breaks down on many machines as a part of an air conditioner. I don't know what this is due to, most likely with the low build quality and insufficient quality parts manufactured for cars. You won't believe it, and I once had to change two compressors: a car air conditioner and a home one. I was shocked by the prices then. The repair specialists told me to do an
aircon chemical overhaul, but I didn't believe that it could help, be honest. But after I did it, everything began to work much better, it's all strange, to be honest!
