Hello, for some time I do not work climate in s-max. I set aside to check and fill, they did everything and finally said the compressor to be replaced. I took out the transmitter, the electromagnet is operational. With the engine running, I left the jumper on the contacts after about 2 minutes, the valve exploded and some gas and green liquid spilled out. In this situation, the compressor is in working order or to be replaced? Where to look further for the cause (pressure sensor)?
