Have a look here:
Always worth paying a bit more for a known members car which will eliminate all the unnecessary traveling that you mention.
I know that the proposed sale has been withdrawn, however may well be worth a PM.
I would go back and check all the fuses in the other fuse boxes with a multi meter before you start looking elsewhere.
I would also check the specific relays.
There are a few common fuses in there, so pay particular attention to those.
How did you get on with the CPS?
I will take that as a no then.
It is within the fuseable link.
It is the only fuse on its own.
The other fuses within the link are all in a row as per your image.
And remember and check your CPS.
The general rule of thumb is to avoid Nissan dealerships.
Also. most Nissan dealerships body swerve JDM imports.
There is a guy about an hour along the coast from you who may be prepared to help, however you would have to get the car to him and I am not sure if this is an option due to the distancing rules that are in place at the minute.
