AC not cooling when the car is not moving

Hi everyone,
I hope this community is still live Our cars are getting older and older so probably most of you moved to new cars already.
I have one issue that is causing me trouble when I travel. The AC unit is cooling pretty well, it is filled with freon every 2 seasons so no issues with that. However, after about 30 minutes of driving, the next time I stop at a traffic light, I hear a sound like a muffled click, and then the AC doesn't cool anymore, instead warm air is being blown inside. The AC or something else is then trying to turn on something I guess, because I hear this "click" sound on 5 seconds, it seems like something needs to be turned on, but very fast it is turned off again. When the car moves again the cooling is back. This is not a big issue, as traffic lights do not last long, however during summer I travel to Greece, and sometimes at the border crossings, you have to wait in the car for about 1-2h on30-40c degrees. If I hit on a gas pedal (when idle) the cooling comes back, but that is not a solution as the revs need to be really high and everyone else is looking at you, like what is this guy trying to do and you cannot sustain that for an hour or two.
I have taken the car to an AC specialist, but they told me that the AC unit is ok, and that there could be something wrong with the Engine, which (probably) doesn't give enough power to the AC unit. I was quite disappointed that this AC repair shop didn;t find the cause for trouble. Any suggestions?
My Megane is 1.9 dci, 2004.
Thank you in advance!
