Where do I find the fuse for the air con and heater fan?

[Fuzz1]

I had the issue of blocked wheel arch drains creating a paddling pool in the drivers footwell. The fan worked during the leak and for 2 days after the leak was resolved. Any idea where the fuse is to check it? My car is the C4 Grand Picasso, 2014, exclusive+ 1.6 Diesel. I’ve had a look at the online literature but not been able to identify anything I can use, also trawled through You Tube with no luck. Cheers in advance for your help.
