My headlights recently stopped working I had the car checked and it was a fuse, I have replaced the fuse and they have gone again, I was then driving back in the dark and had to replace the fuse with the cooling fan fuse but now that has blown, does anyone know what this can be????

 

Yes, I know what it could be: i am 99% sure that this is a short to ground.

The fuse is never at fault. The fuse blows so the car won't catch on fire. That's a pretty good use of 25 cents isn't it?

Now you need to find the short and fix it. This video might help:
