Solution
1. Preparation
  • Tools Required: OBD-II scanner, multimeter, socket set, flat-head screwdriver, Torx screwdriver.
  • Disconnect the negative terminal of the 12V battery to ensure safety while working on the electrical system.
2. Inspect the Wiper Control Stalk
  • Remove the steering column cover using a Torx screwdriver.
  • Disconnect the wiper control stalk wiring harness.
  • Visually inspect the stalk for any damage or debris.
  • Clean the connectors and reassemble the stalk, ensuring it is securely connected.
3. Reset the Wiper System
  • Reconnect the negative terminal of the 12V battery.
  • Power on the vehicle and check the wiper operation.
  • If the wipers are still running, disconnect the battery again.
4. Test the Wiper Motor
  • Locate the wiper motor (usually under the cowl).
  • Use a multimeter to check for voltage at the motor connector while toggling the wiper control.
  • If there is voltage present and the motor does not operate, the motor may need replacement.
5. Replace the Wiper Motor (if necessary)
  • Disconnect the wiring harness from the wiper motor.
  • Remove the mounting bolts securing the motor using a socket set.
  • Install the new wiper motor by reversing the removal steps.
  • Torque the mounting bolts to manufacturer specifications (typically around 10-15 ft-lbs).
