Troubleshooting Windshield Wipers Not Working on a 2020-Present Toyota Highlander (XU70)
Tools Required
  • Screwdriver set (flat and Phillips)
  • Multimeter
  • Fuse puller or needle-nose pliers
  • Wrench set (for wiper arm removal)
  • Flashlight (for better visibility)
Repair Instructions

Step 1: Check the Wiper Switch

  • Action: Turn on the ignition and activate the wiper switch.
  • Test: If the wipers do not operate, proceed to check the fuse.

Step 2: Inspect the Fuse

  • Locate Fuse Panel: Open the driver’s side door and find the fuse panel cover.
  • Remove Fuse: Use a fuse puller to remove the wiper fuse. Inspect it visually.
  • Test with Multimeter: Set the multimeter to continuity mode and check if the fuse is blown. If so, replace it with a new fuse of the appropriate amperage.

Step 3: Examine the Wiper Motor

  • Locate the Motor: Remove the wiper arms by loosening the nuts with a wrench, then lift the arms off.
  • Access the Motor: Remove the plastic cover under the wiper assembly to access the motor.
  • Test Power: Using a multimeter, check for voltage at the motor connector while operating the switch. You should see power at the motor terminals if the switch and fuse are functioning.

Step 4: Check for Obstructions

  • Visual Inspection: Look for ice, snow, or debris blocking the wipers.
  • Manual Movement: Attempt to manually move the wipers to see if they are stuck. If they move freely, reassemble and test again.

Step 5: Test the Wiper Relay

  • Locate Relay: Find the wiper relay in the fuse box.
  • Swap Relay: If you have a similar relay, swap it out. If the wipers start working, replace the faulty relay.
Final Steps
  • If all steps above do not resolve the issue, you may need to replace the wiper motor or further investigate the wiring harness for any breaks or shorts.
  • After any repair, reassemble all components and test the wipers in all settings to ensure proper operation.
Conclusion

By following the above diagnostic steps and repair instructions, you should be able to troubleshoot and resolve the issue with your Toyota Highlander's windshield wipers. If the problem persists, it may be advisable to consult a professional technician for further diagnosis.
