Symptoms
  • Wipers do not operate at all when the control stalk is activated.
  • No sound or movement when the wipers are turned on.
  • Check the wiper control on the dashboard for any warning lights.
  • Intermittent wiper function may be erratic or completely non-functional.
Diagnostic Steps

  1. Check for Power:

    • Use an OBD-II scanner to check for any related error codes that may indicate a malfunction in the wiper system or related electrical components.

  2. Inspect the Wiper Fuse:

    • Locate the fuse box (usually found under the dashboard or in the engine compartment).
    • Refer to the owner's manual for the specific fuse related to the windshield wipers.
    • Remove the fuse and inspect it. If it appears blown, replace it with one of the same amperage.

  3. Test the Wiper Switch:

    • With the multimeter, check the power at the wiper switch.
    • If no power is detected at the switch, the switch may be faulty and require replacement.

  4. Check the Wiper Motor:

    • Find the wiper motor (usually located under the cowl panel).
    • Disconnect the electrical connector and use a multimeter to test for power at the motor terminals when the wiper switch is activated.
    • If there is power but the motor does not operate, the motor may be defective.

  5. Inspect Wiring and Connectors:

    • Check for any loose or damaged wiring and connectors leading to the wiper motor.
    • Ensure all connections are secure and free of corrosion.
Repair Instructions

  1. If the Fuse is Blown:

    • Replace the blown fuse with a new one of the same amperage. This usually takes about 10 minutes.

  2. If the Wiper Switch is Faulty:

    • Remove the steering column covers using a socket set.
    • Disconnect the wiring harness from the wiper switch.
    • Replace with a new switch (part number can be found in the manual).
    • Reassemble the steering column covers and test the wipers. Estimated time: 30-45 minutes.

  3. If the Wiper Motor is Defective:

    • Remove the wiper arms (use a wiper arm puller if necessary).
    • Unscrew and remove the cowl panel to access the motor.
    • Disconnect the motor's electrical connector and unscrew the motor from its mount.
    • Install the new motor in reverse order, ensuring all connections are secure. Estimated time: 1-2 hours.
Safety Warnings
  • Always disconnect the vehicle battery before working on electrical components to avoid shocks or shorts.
  • Use appropriate tools and safety gear to prevent injury. When working under the cowl, be cautious of sharp edges and components.
