I took the car to an AC Mec. He had checked the switch mounted on the AC filter bottle through a tester. It was not getting the current. (On which one can see the gas flow as there is a transparent window). So after that he just pulled a relay as shown in the pic. This relay was behind the battery having around 8 pins or so.(The relay no as shown in the pic is 003-545) While he was pulling the relay I heard the compressor getting engaged for a second. So he just cleaned the legs of the relay and plugged it back to its place.

For the whole day my car AC was working very fine. I asked the tec that what was the defect. He laughed and said even he never knew what was it……………… But thanks God the AC is working till now………
