Right Side windshield wiper problem

[Fjalle]

C5 -08 new model.
Wiper goes up and stays there. Wiper engine vorks. It's not broken.
Left wiper works ok.
Very grateful for Your help

It sounds like the gearbox has jammed or broken. They are quite easy to remove, 3 x 10mm bolts from memory after you remove the cover. Take the opportunity to clean and grease the other side as well.
