Fiesta ZS Mk7 fan won't stop cooling

[Pixie2203]

For some reason my fan came on as soon as I turned my engine on and it's not stopped since, this hasn't happened before normally it'll come on for a few minutes once I've turned my engine off. I'm assuming this isn't normal? Can anyone advise me on what I should do? 

 

***update, my battery has gone flat yet my car wasn't on, now my car won't even lock so waiting on breakdown recovery***

Sounds like the fan relay is jammed on. Get the recovery man to start your car then thump the relays to release the current flow. Or remove relay so when you do stop again it won't stay on.new relay is required asap.
