Repair Instructions

Step 1: Check Washer Fluid Level

  • Action: Open the hood and locate the washer fluid reservoir. Ensure it is filled with washer fluid. If low, refill as necessary.

Step 2: Inspect and Test the Washer Pump

  • Action:
    1. Disconnect the washer fluid pump connector.
    2. Set the multimeter to the DC voltage setting.
    3. With the ignition on and the washer switch activated, probe the pump connector terminals.
    4. If there’s no voltage, trace back to the switch or check for a blown fuse.

Step 3: Replace the Washer Pump (if necessary)

    2. Disconnect the pump wiring harness and the washer fluid hose.

    2. Use compressed air or a fine pin to clear any debris.
    3. Adjust the nozzle angle if necessary for better spray coverage.

Step 5: Check and Replace Fuse (if blown)

  • Action:
    1. Consult the owner’s manual to locate the fuse associated with the windshield washer system.
    2. Remove the fuse and inspect it for continuity. Replace with a new fuse of the same amperage if blown.

Step 6: Test the System
