Repair Instructions

Step 1: Replace Blown Fuse (if applicable)

  1. Identify the Wiper Fuse:

    • Refer to the fuse diagram in the owner’s manual.

  2. Remove the Fuse:

    • Use the fuse puller tool (often included in the fuse box) to extract the blown fuse.

  3. Install New Fuse:

    • Replace it with a fuse of the same rating (ampere).

Step 2: Replace Wiper Motor (if necessary)

  1. Disconnect Battery:

    • Disconnect the negative terminal of the battery to prevent electrical shock.

  2. Remove Wiper Arms:

    • Use a flathead screwdriver to gently pry off the plastic cover at the base of the wiper arms.
    • Use a socket wrench to remove the nut securing each wiper arm, and lift the arms off.

  3. Access the Wiper Motor:

    • Remove the screws/bolts securing the wiper motor (found under the plastic cowl cover).
    • Carefully lift the cowl cover to expose the motor.

  4. Disconnect Wiring Harness:

    • Unplug the wiring harness from the wiper motor.

  5. Remove Old Motor:

    • Extract the wiper motor from its mounting position.

  6. Install New Motor:

    • Position the new wiper motor and secure it with screws/bolts.
    • Reconnect the wiring harness.

  7. Reinstall Wiper Arms:

    • Position the wiper arms back onto the motor, securing them with the nuts and replacing the plastic covers.

Step 3: Replace Wiper Blades (if necessary)

  1. Remove Old Wiper Blades:

    • Lift the wiper arm away from the windshield.
    • Press the release tab on the wiper blade connector and slide the blade off the arm.

  2. Install New Wiper Blades:

    • Slide the new wiper blade onto the arm until it clicks into place.

  3. Lower Wiper Arms:

    • Carefully lower the wiper arms back onto the windshield.
Final Check
  1. Reconnect Battery: Reconnect the negative terminal of the battery.
  2. Test Wipers: Activate the wipers to ensure they function correctly at all speeds and settings.
