As of today, the left wiper stopped working lets hope there are parts...
Great news! Always make sure your nuts are tight.So I put on my mechanical hat this morning, pulled away the black cap, tightened the nut and hooray... the wiper is working again.
So apparently it can loose. Was it not tight enough from the factory, was it while cleaning, I don't know, but at least I got it working again.
Thx Lormax and Harleyguy for the tip.
