Front wiper C3

Hello, very good, I address you to see if you can help me since I have a problem I call in a C3 1.4 HDI.
The owner of the car tells me that Ivan running a rainy day with the clean and good at first stops working. I bring it to me and it does not work when I give him in command of the one with 2000. But then I act on the lever to me. For the water to jump and it is brought intermittently.
I have looked at him fuses and everything is crazy. If you could give me advice thanks.
