how to fix Tesla Model Y Current (2020-present) windshield wipers not working

Solution

1. Preparation

• Gather all necessary tools and parts.
• Disconnect the vehicle's 12V battery to ensure safety while working on electrical components.

2. Check and Replace Fuse

• Locate the fuse box, typically under the dashboard or in the trunk.
• Remove the cover and find the windshield wiper fuse (refer to the owner's manual for exact location).
• Use a multimeter to check for continuity. If blown, replace with the same amperage fuse.
• Reinstall the fuse cover and reconnect the battery.

3. Inspect and Repair Wiring

• Inspect the wiring harness connected to the wiper motor for any visible signs of damage or corrosion.
• If damaged, repair the wiring using solder and heat shrink tubing or replace the harness as necessary.
• Ensure all connectors are secure and free from corrosion.

4. Test Wiper Motor

• Disconnect the wiper motor from its connector.
• Use jumper wires to apply power directly to the motor (positive to positive, negative to negative).
• If the motor operates, reconnect it properly; if not, replace the wiper motor.

5. Reassemble and Test

• Reassemble any components that were removed during the inspection.
• Reconnect the vehicle's battery.
• Test the windshield wipers to confirm proper operation.
