Windshield Wiper Malfunction in 2022 Toyota Highlander

Step 1: Visual Inspection

  • Tools Required: None
  • Inspect the wiper blades for condition. Look for cracks, tears, or missing parts.
  • Check the wiper arms for damage or looseness.
  • Ensure that the wiper linkage is intact and not disconnected.

Step 2: Check Wiper Fuse

  • Tools Required: Fuse puller or needle-nose pliers
  • Locate the fuse panel. For the 2022 Toyota Highlander, the fuse panel is typically located under the dashboard on the driver’s side or in the engine compartment.
  • Inspect the diagram on the fuse panel cover for the windshield wiper fuse (often labeled "Wiper" or "WIPER").
  • Pull the fuse and inspect it. If the fuse is blown, replace it with one of the same amperage.

Step 3: Test Wiper Switch

  • Tools Required: Multimeter
  • Turn the ignition to the ON position (do not start the engine).
  • Using a multimeter, check for power at the wiper switch.
  • If there is no power, the wiper switch may need to be replaced.

Step 4: Check the Wiper Motor

  • Tools Required: Multimeter, socket set
  • Disconnect the wiper motor connector located at the base of the motor.
  • Use a multimeter to check for voltage at the connector while toggling the wiper switch.
  • If there is no voltage, the issue may lie with the wiper relay or wiring.
  • If voltage is present but the motor does not operate, the wiper motor may be faulty and require replacement.

Step 5: Inspect Wiper Relay

  • Tools Required: Multimeter, socket set
  • Locate the wiper relay in the fuse panel (check the owner’s manual for exact location).
  • Swap the wiper relay with another identical relay (e.g., horn relay) to test functionality.
  • If the wipers work with the swapped relay, replace the faulty relay.
Repair Instructions

Repairing or Replacing Wiper Motor

If the wiper motor is faulty, follow these instructions:

  1. Disconnect the Battery

    • Tools Required: Wrench (10mm)
    • Disconnect the negative terminal of the battery to prevent electrical shock.

  2. Remove Wiper Arms

    • Tools Required: Wiper arm puller (optional), socket set
    • Remove the plastic covers at the base of the wiper arms.
    • Use a socket to remove the nut securing each wiper arm and gently pull them off.

  3. Remove the Wiper Motor

    • Tools Required: Socket set, Torx bits (if applicable)
    • Locate the wiper motor under the cowl (plastic cover at the base of the windshield).
    • Remove the screws or bolts securing the wiper motor.
    • Disconnect the wiring harness from the motor.
    • Carefully pull the motor out of its mounting position.

  4. Install the New Wiper Motor

    • Tools Required: Socket set
    • Position the new wiper motor in place and secure it with screws/bolts.
    • Reconnect the wiring harness to the new motor.

  5. Reinstall Wiper Arms

    • Place the wiper arms back onto their respective posts and secure them with nuts.
    • Replace the plastic covers.

  6. Reconnect the Battery

    • Reconnect the negative terminal of the battery.

  7. Test Operation

    • Turn on the ignition and test the wipers for proper operation. Ensure they function correctly in all modes (intermittent, low, and high).
Conclusion

If the wipers still do not function properly after these diagnostics and repairs, it may be necessary to seek professional assistance, as the problem could be more complex, involving the vehicle’s body control module or other electronic components. Always refer to the vehicle’s service manual for specific details and torque specifications.
