Wiper motor replacement?

Unfortunately, we don't have a manual on this specific vehicle so I can't give you the repair process for it because it is not offered in the USA. However, we do have a similar vehicle that the process is going to be almost identical so it should help get you to where you need to be.

Plus here is a general video that shows how to replace a wiper motor that will help as well:
