A / C malfunction

Hello friends, my car 2004 206 x-line, there were leaks in the air conditioner, I had them built right now, there is no leak, but the air conditioner does not come on, although the gas is full. What do you think could be the reason why they said we could take the breast and I brought the car.

They said that there is a button in the chest and it came to me a lot. Could it be from the pressure sensor?

Let me tell you, when the air conditioner button is pressed, its light is on but the air conditioner is not activated. They couldn't find the reason for that

thank you thank you

greetings lie under the front bumper air conditioner comp. the plug can be unplugged or engraved. The same thing happened to me. If you check the socket is open and where the water can get wind, maybe the breakdown is there.
