Loose terminations, faulty accessory, damaged cable. If it’s never worked it could be a load of things tbh.
One easy way to do some diagnosis would be to spend a tenner on a socket tester.

I had a spare socket so I swapped it and that seems to work. I didn't know socket testers existed though so thanks for the tip.
