scenic 2 1.5 dci air con..

Just had my scenic"s air con checked and charged up but the system isn't working. .switch light is on when pressed but nothing.

Guy at ats said it could hopefully be a fuse..

Any help would be appreciated in finding said fuse or fuses as looking at the haynes manual it could have 3??

Is it the 40 amp in the top fuse board in the engine bay?

I quickly tried to test if the compressor was getting power but showed nothing?
