I have been facing this serious issue for many days where the wiper starts and stops anywhere on its own. I have changed the motor, checked the fuses and relay. What is the solution for this issue?
The rear wiper and both water power jets work fine. I have also checked the rain sensor wiring and changed the wiper switch on the steering wheel. Please suggest.

Hello,

There is a wiper module called an upper electronic module forward of the roof console. Which is sounds like is going out. Here is a wiring diagrams to help you see how the system works. I would start by removing the electrical connector and looking for corrosion which will cause the issue.

Check out the wiper wiring diagrams (below). Please let us know what you find.

Cheers, Ken
