Repair Instructions

Step 1: Replace the Washer Pump (if necessary)

  1. Remove the Washer Fluid Reservoir:

    • Locate the mounting bolts that secure the reservoir to the vehicle (usually on the top and sides).
    • Use a socket or wrench to remove the bolts.
    • Disconnect the washer fluid hose from the bottom of the reservoir.

  2. Disconnect the Electrical Connector:

    • Locate the washer pump on the bottom of the reservoir.
    • Carefully disconnect the electrical connector from the pump.

  3. Remove the Old Pump:

    • Twist or pull the washer pump out of the reservoir (some models may require a gentle pry).
    • Ensure the old pump is cleanly removed without damaging the reservoir.

  4. Install the New Washer Pump:

    • Insert the new washer pump into the reservoir, ensuring it is seated properly.
    • Reconnect the electrical connector to the new pump.

  5. Reattach the Reservoir:

    • Reconnect the washer fluid hose to the bottom of the reservoir.
    • Position the reservoir back into place and secure it with the mounting bolts.

Step 2: Test the System

  1. Refill Washer Fluid:

    • Use a funnel to refill the washer fluid reservoir with appropriate washer fluid.

  2. Activate the Washer System:

    • Turn on the ignition, if necessary, and activate the washer control to test the pump.
    • Ensure fluid sprays from the nozzles and that there are no leaks.

  3. Check for Proper Operation:

    • Inspect the spray pattern and ensure both nozzles are functioning.
    • If the system works correctly, close the hood and perform a final check.
Conclusion

By following these steps, you should successfully diagnose and repair the windshield washer pump issue in your 2023 Toyota Highlander. Always ensure that you are using the correct replacement parts and follow all safety protocols when working on your vehicle. If problems persist after these steps, further diagnosis may be necessary, potentially involving scanning for error codes with an OBD-II scanner.
