Windscreen wiper and broken fuse

Hi everybody

As everyday has got his mecanical problem, today let's speak about windscreen wiper.
Since 2 days, they work 2 minutes and then the 20A fuse breaks... I follow the electric cable and so one... but no idea from where it comes, does someone had got the same problem?

I also see that on the oil plug (yellow) there is always water when it s raining a lot around it... So i m wondering if it can have a link in between my both problem.
See you !!
Have a nice rainy day.

The blowing fuse is most likely to be the wiper motor.

The water which collects around the oil filler comes from the washer jet, allowing water on the bonnet to drip through.
