Windshield Wiper Malfunction Repair for 2022 Toyota Highlander
Tools Required
  • Flathead screwdriver
  • Phillips screwdriver
  • Multimeter
  • Replacement fuses (if necessary)
  • Wrench set
  • Pliers
  • Safety glasses
  • Torque wrench (for reassembly)
Repair Instructions

1. Replacing the Wiper Fuse (if blown)

  • Access the fuse box as described.
  • Replace the blown fuse with a new one of the same amperage.
  • Re-test the wiper operation.

2. Replacing the Wiper Motor

  1. Remove the Wiper Arms:

    • Use a flathead screwdriver to gently pry off the plastic covers at the base of the wiper arms if present.
    • Use a 14mm or appropriate socket to remove the wiper arm nuts. Pull the wiper arms straight up and off the splined shaft.

  2. Remove the Cowl Panel:

    • Unscrew the screws securing the cowl panel (these may be Phillips or Torx screws).
    • Carefully pull the cowl panel away to expose the wiper motor.

  3. Disconnect the Wiper Motor:

    • Unplug the electrical connector from the wiper motor.
    • Remove the mounting bolts (usually 10mm) securing the motor to the vehicle.

  4. Install the New Wiper Motor:

    • Position the new motor in place and secure it with mounting bolts.
    • Reconnect the electrical connector.

  5. Reassemble the Cowl Panel and Wiper Arms:

    • Reinstall the cowl panel, ensuring it fits snugly and all screws are tightened.
    • Position the wiper arms back onto the splined shafts, ensuring they are aligned correctly.
    • Tighten the wiper arm nuts and replace the plastic covers.

3. Testing the Repair

  • Turn on the ignition and test the wipers through all settings (off, low, high, intermittent).
  • Ensure the wipers operate smoothly and return to the resting position.
Conclusion

If the windshield wipers are still malfunctioning after performing these steps, the issue may be more complex, potentially involving the vehicle’s Body Control Module (BCM) or wiring issues. In such cases, it is advisable to consult professional assistance or a certified Toyota technician.
