how to fix my Volkswagen Passat B8 (2015-2022) windshield wipers not working?

Solution

1. Preparation

• Gather all necessary tools and parts.
• Ensure the vehicle is parked on a level surface, and the engine is off.
• Disconnect the battery to prevent any electrical shorts.

2. Inspect and Replace the Fuse

• Locate the fuse box, typically found under the dashboard or in the engine compartment.
• Identify the specific fuse for the windshield wipers (refer to the owner's manual for the exact location).
• Remove the fuse using a fuse puller or pliers.
• Inspect the fuse for continuity; replace if blown with a new fuse of the same amperage.

3. Test and Replace the Wiper Motor

• Reconnect the battery temporarily.
• Turn on the ignition and engage the wiper switch to check if the motor runs.
• If the motor does not operate, disconnect the battery again.
• Remove the wiper arm and cover to access the wiper motor.
• Disconnect the wiring harness from the motor.
• Use a multimeter to check for voltage at the motor's connector when the wiper switch is activated. If voltage is present, the motor is faulty and needs replacement.
• Replace the wiper motor with a new one, ensuring all connections are secure.

4. Check Wiper Linkage

• With the motor removed, inspect the wiper linkage for any disconnections or damage.
• Ensure that the linkage moves freely and is properly connected to the motor.
• If any components are damaged, replace them accordingly.

5. Reassemble and Test

• Reinstall the wiper motor and any covers removed during the process.
• Reattach the wiper arm, ensuring it is positioned correctly.
• Reconnect the battery and test the wipers in all settings (intermittent, low, high).
