C4 grand Picasso AC not working / fuses?

[Matchbookfail]

Morning all
I have a Grand C4 Picasso, Petrol 1.2l PureTech Auto, 2017
(As an aside does this have a short designation? I see some posts referring to their cars as such eg ‘X7’)

It’s happened a couple of times now, but when it has been really hot the AC stops working (providing cold air), turning the car off and on again provides cold air for a minute then it goes back warm, the next day it has been fine and worked as it should.
I wonder if this is heat soak in the engine/ac system, and as a protection to stop extra heat being added to the engine bay from the ac system it is disabled?

Alternatively is there a separate fan for the ac Rad (I thought not) but I found on the fuse list there seems to be.
Here is the details of fuse board 1; which I can’t seem to find behind the glove box.
Fuse box 2 seems to be behind a load of connectors but I can’t find 1.

Attached pictures

Thanks in advance

You might be on the right track with this statement. However, it is very important to state whether the aircon is producing cold air or not.
If it is producing cold air and the radiator fan is running as the outside temperature is getting hot, then the system might be over charged.
As the car is only 5 years old it should have the correct refrigerant charge from the factory. It really shouldn't have aircon problems this early in it's life...but then again. Are you the original owner? Has the air conditioning ever been "serviced" since new? Has it been serviced recently?
There are a number of possibilities, like a blockage or over charge, but that depends on the answers to the above questions.
