issues with wiper headlights.

[chilin]

Hello,
This is the first post I publish. I read you when I can and I have learned a lot with this forum.
I have a problem with the headlight wipers.
When I put the position light, the headlight wiper on the passenger side (EU version) moves a little. If I go through the cycle of putting on the lights and hitting the water jets, sometimes it works and sometimes it doesn't.
I changed the light switch but it's still the same. Even one day, the ejector pump started up. I have searched for information and I don't know if it is a problem with the relay, the motor, the electrical installation.....
Can someone help and guide me?
Thank you all so much for your help.

Hi again!
I don't know where is the problem.
I disassembled the headlight wiper motor, cleaned and greased it and reassembled it.
Now when I put the lights on, the wiper motor moves a little bit, just like before.
But now the headlight washer pump turns itself on and doesn't stop until I turn off the lights. (The pump works, but doesn’t dischargue water.)I don't know where the problem could be, I even looked at the relay, but I don't know how to check it.any suggestions?
Thank you
