Safety Function In The Event Of Failure (Motor Block)

Two types of motor block can be distinguished in the rain sensor control module:
1. The front windscreen wiper does not leave the parking position when activated. If the windscreen wiper does not move despite the appropriate power supply, actuation of the windscreen wiper motor is interrupted after 3 seconds.
2. The front windscreen wiper locks after leaving the parking position.
In both cases all operating modes are blocked after a motor block. The system can only be reactivated after the steering column switch has returned to the >OFF< position.
If one of these faults is present, replace the rain sensor control module.
