yep got a re-gas recently  the guy said it didn't really need a top up.. the air con wouldn't blow cold at the time , he had the bonnet poped and he said the air con systm sounded like it wanted to go but wasn't kicking in,, he told me to drive for a while and keep hitting tie air con button on/off and it might encouagre it to work,

 

eventually after a week or so it didi work but only for a few days? and ideas

Time to visit an A/C specialist.

Its on MAX fan on COLD (blue) with air con light on and in recirculation mode on dual setting (both for driver and passenger)?

 

I had a problem before when my air con in my former car kept cutting out at a set temp.

It meant it was never cold - but u can hear from the engine a CLICK every couple of seconds. Not sure wot the dealer did - but they fixed it.

 

So if the air con service checked the top up and leaks then it s something else.

As Silver1011 said - maybe see a specialist...

As silver said: go see an a/c specialist. It could be something major like a faulty compressor, or something minor like a faulty temperature sensor.
