Common Problems with Windshield Wipers on the 2020 Toyota Highlander

Windshield wipers are crucial for maintaining visibility in adverse weather conditions. The 2020 Toyota Highlander, like many vehicles, can experience several common wiper-related issues. Below are the symptoms, diagnostic steps, and potential repair instructions for these problems.

Common Symptoms

  1. Wipers Not Working at All

    • Symptoms: Wipers do not move, regardless of switch position.

  2. Inconsistent Wiper Speed

    • Symptoms: Wipers operate at an erratic speed or may not switch between intermittent and continuous modes properly.

  3. Streaking or Poor Visibility

    • Symptoms: Wipers leave streaks on the windshield or do not clear water effectively.

  4. Wiper Motor Noise

    • Symptoms: Grinding or clicking noise when wipers are activated.

  5. Wipers Stopping Mid-Sweep

    • Symptoms: Wipers fail to complete their cycle and stop at odd positions.

Tools Required

  • Multimeter
  • Wrench set
  • Screwdriver set
  • Windshield wiper blade replacement
  • Electrical contact cleaner
  • Lubricant (e.g., silicone spray)
  • Safety glasses
  • Gloves

Step 1: Check Fuses

  1. Locate the Fuse Box: Refer to the owner’s manual to find the fuse box location.
  2. Inspect Wiper Fuse: Identify the fuse related to the windshield wipers and inspect it for continuity using a multimeter.
    • If Blown: Replace the fuse and test the wipers.

Step 2: Test the Wiper Switch

  1. Access the Wiper Switch: Remove the steering column cover to access the wiper switch.
  2. Multimeter Test: With the multimeter, check for power at the switch when activated.
    • If No Power: Inspect wiring and connections for damage.

Step 3: Inspect Wiper Motor

  1. Locate the Wiper Motor: Usually found under the plastic cover at the base of the windshield.
  2. Check Electrical Connections: Ensure all connectors are secure and free from corrosion.
  3. Test Motor Operation: Apply direct power from a battery to the motor terminals to see if it operates.
    • If Motor Fails to Operate: Replace the wiper motor.

Step 4: Inspect Wiper Blades

  1. Visual Inspection: Check the rubber for wear, cracks, or stiffening.
  2. Test Wiper Action: Run the wipers and observe their movement.
    • If Streaking: Consider replacing the wiper blades.

Step 5: Check Wiper Linkage

  1. Access the Linkage: Remove the wiper arms and the plastic cover over the motor.
  2. Inspect Linkage: Look for any loose or damaged connections.
    • If Loose: Tighten or replace the linkage.

  3. Unscrew and Remove the Motor: Use the appropriate wrench to remove screws securing the motor assembly.
  4. Install New Motor: Position the new motor in place and secure it with screws.
  5. Reconnect Wiper Arms: Ensure they are aligned correctly before tightening down.
