Solution
1. Preparation
  • Ensure the vehicle is parked on a level surface and power is off.
  • Disconnect the vehicle’s battery to prevent electrical shorts during repair.
2. Inspect Wiper Assembly
  • Remove the wiper arms:
    • Use a 13mm socket to remove the nut securing each wiper arm.
    • Gently lift the wiper arms off the splined shafts.
  • Check the wiper motor and linkage:
    • Visually inspect the wiper motor for any signs of damage or corrosion.
    • Inspect the linkage for any binding or disconnection.
3. Test and Repair Wiper Motor
  • Reconnect the battery temporarily to test the wiper operation:
    • Activate the wipers and observe their movement.
  • If the motor is faulty:
    • Disconnect the battery again.
    • Remove the wiper motor by unscrewing the mounting bolts (typically T20 Torx).
    • Disconnect the wiring harness from the motor.
    • Install the new wiper motor by reversing the removal process.
4. Check and Replace Relay/Fuses
  • Locate the fuse box, typically under the dashboard:
    • Check the wiper fuse (refer to the owner’s manual for the exact fuse number).
    • If the fuse is blown, replace it with the same amperage rating.
  • Test the wiper relay:
    • If faulty, replace it with a new relay.
5. Reassemble and Test
  • Reattach the wiper arms to their respective splines and tighten the securing nuts.
  • Reconnect the battery and perform a final test of the wipers.
  • Ensure they operate correctly and return to the resting position.
