The loss of contact may result in complete failure of the wiper motor. An (additional) earth cable must be mounted to repair this situation.
- Install additional earth cable.
- Check fuse.
- Check operation of windshield wiper motor.
The vehicle manufacturer is already aware of the problem. As part of a service action, the vehicles are checked and a new (additional) earth cable is installed.
Nevertheless, one may assume that for various reasons not all vehicles have been checked and repaired.
