1. Faulty Switch: The rear wiper switch itself may be faulty and stuck in the on position. Try operating the switch multiple times to see if it resolves the issue. If it doesn't, the switch may need to be replaced.
2. Wiper Motor or Relay Issue: The rear wiper motor or the relay that controls it could be malfunctioning. Check for any loose connections, damaged wires, or corrosion around the motor and relay. If there are any issues, they will need to be repaired or replaced.
3. Faulty Wiring: There may be a problem with the wiring that controls the rear wiper. Inspect the wiring for any breaks, loose connections, or shorts that may be preventing the wiper from turning off. If you find any issues, repair or replace the damaged wiring.
4. Body Control Module (BCM) Issue: The BCM controls various electrical functions in the vehicle, including the rear wiper. If the BCM is malfunctioning, it may cause the wiper to stay on continuously. You may need to have the BCM diagnosed and repaired or replaced.
5. Water Ingress: If there has been water ingress in the area around the rear wiper motor or the BCM, it could cause electrical issues and prevent the wiper from switching off. Check for any signs of water damage and have the affected components dried and repaired.
If you are unable to identify or fix the issue yourself, it is recommended to consult with a trusted mechanic or an authorized Skoda service center. They can properly diagnose and repair the rear wiper issue to ensure it functions correctly.
