peugeot 307 air conditioner blows hot

Hello friends; today i went to the industry for antipollution fault warning, connected it to the computer and turned off the light. But the air conditioner started blowing hot, could the master make a mistake when it was connected to the computer?

When you turn on the air conditioner (ac button), the air conditioner compressor on the alternator belt should be activated with a "click" sound.
If there is no gas in the kilma system, it blows warm and does not cool.

If there is gas in the system, if the compressor is activated, if the pipes behind the right headlight are blowing like hot despite the gray head there, it is not working as the part that separates cold / hot.

it seems as if the air conditioner path seems to be possible. I hope it's a simple thing, it doesn't cost a lot.

There is gas in the system, the compressor comes into play, but it was blowing cold before connecting to the computer that confused me, it started blowing hot when I came out of the mechanic, could there be an error while installing the software? Because while the master adapted the software, the cable did something, then he did something and he collected the computer.

Today I went to another service, the air conditioner vending machine was blocked, the master cleared the error and the problem disappeared. He did not even charge for this transaction.

because of these master-looking butchers, many people are getting cold from their cars.
