how to fix the windshield wiper issue on my Volkswagen Golf MK5 (2004-2008)?

Solution

1. Preparation

• Tools Required: Socket set, multimeter, screwdriver set, flashlight, safety goggles.

2. Check and Replace Fuse

• Locate the fuse box (usually under the dashboard or in the engine compartment).

• Inspect the fuse; if blown, replace it with a new one of the same amperage.

3. Inspect and Repair Wiring

• Reconnect the battery and use the multimeter to check for power at the wiper motor connector.
• If no power is present, trace the wiring harness for breaks or frays.
• Repair any damaged wiring by splicing in new wire of the same gauge.

4. Replace Wiper Motor (if defective)

• Remove the wiper arms by unscrewing the nut at the base of each arm.
• Disconnect the wiper motor by removing the mounting bolts.
• Replace the motor with a new or refurbished unit.
• Reconnect the motor's electrical connector and ensure it is secure.

5. Reassemble and Test

• Reinstall the wiper arms and secure them with nuts.
• Reconnect the battery and test the wipers for proper operation across all settings.
