Car Ac Gas Charging || How To Fill Gas In Car Ac(Indica Vista)

I made this video for learning purpose only.
My car ac compressor was not working,so I went to mechanic to diagnose why compressor is not working? Mechanic checked that there was no gas (R134a) in ac system because of that ac compressor was not working. There is a sensor on high pressure pipe/valve which sends signal to car's ECU to start the compressor and there was no gas in ac system due to that sensor was not working and ECU did not allow the compressor to start.
Then ac system was given air pressure to detect the leakage, and it was diagnosed by mechanic that there is high pressure valve leakage and on account of that car refrigerant got leak. After that both LP and HP valves changed, and ac system was vaccumed by gas charging machine and again machine found leakage in the system. This time, there was leakage in LP valve even after installing new valve, so mechanic suggested to replace the valve port from small to large one then I got it changed. After that there was no any leakage in the ac system , and finally machine charged the oil and gas in ac system and finally compressor started working.Eventually car started blowing cool air.
