Hi guys/girls

I have a electrical battery drain on my fiesta turbo, it’s concerning the relay in the fuse box which runs the interior & exterior fan, front fogs ect. I’m sure you know which one I’m talking about.
It constally stays warm 24hours a day 7 days a week. The only thing I’ve done is to change the relay which has had the same effect on both.

Please someone help, I have heard of this problem before I hoping someone can suggest something I can try

PAUL
