Seat Arosa diesel wiper problem

The described symptoms, specifically the non-functional windshield wipers and the stored error code, do indeed point towards an electrical issue within the wiper system. Given the suspicion of a defective cable or plug connection, it would be prudent to begin with a thorough visual inspection of the wiring harness and associated connectors, particularly those located near the steering column and the wiper motor itself. Pay close attention to any signs of corrosion, damage, or loose connections. Does the Arosa have a rain sensor? If so, its wiring and connection to the wiper system should also be examined.

Where exactly should I look near the steering column? Is there a specific plug or wire I should be checking first?

Considering your expertise level, I would recommend a cautious approach. The wiring harness runs along the steering column, and the wiper switch is connected to it. Look for any obvious breaks or disconnections. However, without diagnostic equipment, pinpointing the exact location will be difficult. If you are not comfortable performing electrical troubleshooting, it might be best to have a qualified technician diagnose the issue to avoid further complications. The error code stored in the memory would provide valuable information for a professional. It seems your estimation of 95€ for repair is reasonable.

Workshop confirmed a faulty connection in the wiring harness near the steering column. 95€ fixed it. Thanks for the input.
