  • Inspect for any blown fuses in the wiper circuit.
• Wipers Moving Slowly or Intermittently:
  • Check for any obstructions on the windshield or wiper arms that might be impeding movement.
  • Ensure the wiper blades are not excessively worn or stiff, which can increase motor load.
  • Verify the power supply is stable and not experiencing voltage drops.
• Wipers Not Parking Correctly:
  • Check the connection to the 'Self Park' wire (Wire 1).
  • Ensure the motor is correctly installed and not misaligned.

If these steps do not resolve the issue, it is advisable to seek assistance from a qualified automotive or marine technician.
