how to fix the rear window wiper not working on my Toyota RAV4 XA40 (2013-2018)

Solution

1. Preparation

• Gather necessary tools and parts.
• Ensure the vehicle is parked on a level surface with the ignition off.
• Disconnect the battery to prevent any electrical shorts.

2. Check and Replace Fuse

• Locate the fuse box (typically under the dashboard or hood).
• Identify the rear wiper fuse (refer to the fuse diagram).
• Remove the fuse using a fuse puller or pliers and check for a blown filament.
• If blown, replace with a new fuse of the same amperage (typically 15A).

3. Inspect and Replace the Wiper Motor

• Remove the Wiper Arm:
  • Use a 14mm socket to remove the nut securing the wiper arm.
  • Gently pry the wiper arm off the motor shaft using a wiper arm puller if necessary.
• Disconnect the Motor:
  • Locate the motor connector and carefully disconnect it.
• Test the Wiper Motor:
  • Connect the motor directly to a 12V power source to verify it operates.
• Replace Motor if Faulty:
  • If the motor does not run, replace it with a new one. Install in reverse order of removal.

4. Reassemble Components

• Reattach the wiper arm securely and torque the nut to approximately 10 Nm (7 ft-lbs).
• Reconnect the battery and ensure all components are properly secured.
