If your 2020 Toyota Highlander’s windshield wipers are not working, it could be a result of several possible issues. Below, I will outline the symptoms, diagnostic steps, tools required, and repair instructions to help you troubleshoot and resolve the problem effectively.

Tools Required
  • Multimeter
  • Screwdrivers (Phillips and flathead)
  • Wrench set
  • Pliers
  • Trim removal tools
  • Replacement fuses (if necessary)
  • Replacement wiper motor (if necessary)
Repair Instructions

Step 1: Replace the Wiper Fuse

  1. Locate the Fuse: Refer to the owner’s manual for the exact location of the wiper fuse.
  2. Remove the Fuse: Using a fuse puller or pliers, gently pull out the fuse.
  3. Inspect the Fuse: Check if the metal strip inside the fuse is broken. If it is, replace it with a new fuse of the same amperage.
  4. Test the Wipers: Turn on the wipers to see if they function correctly.

Step 2: Replace the Wiper Motor (if necessary)

  1. Disconnect the Battery: Disconnect the negative terminal to prevent any electrical shorts.
  2. Access the Wiper Motor: Remove the wiper arms using a flathead screwdriver and a puller if necessary. Remove the cowl cover to access the wiper motor.
  3. Remove the Wiper Motor: Disconnect the electrical connector from the motor. Unscrew the mounting bolts and remove the motor.
  4. Install New Wiper Motor: Position the new wiper motor in place. Secure it with the mounting bolts and reconnect the electrical connector.
  5. Reassemble: Reinstall the cowl cover and wiper arms.

Step 3: Test All Functions

  1. Reconnect the Battery: Reattach the negative terminal of the battery.
  2. Test the Wipers: Turn the ignition back on and test all wiper functions (low, high, and intermittent).
Conclusion

If after following these steps the wipers still do not work, it may be advisable to consult a professional technician or visit a Toyota dealership for further diagnostics. There may be underlying issues such as a faulty Body Control Module (BCM) or other electrical problems that require specialized equipment to diagnose.
