Solution
1. Preparation
  • Gather all necessary tools and parts.
  • Disconnect the vehicle battery to ensure safety while working on electrical components.
  • Tools Required: Socket set, multimeter, flathead screwdriver, torx screwdriver.
2. Check and Replace Fuse
  • Locate the fuse box: Refer to the owner’s manual for the exact location of the rear wiper fuse.
  • Inspect the fuse: Remove the fuse and check if it is blown. Replace with the same amperage if necessary.
  • Reconnect the battery: After replacing the fuse, reconnect the battery.
3. Inspect and Repair Electrical Connections
  • Access the rear wiper motor: Remove the interior trim panel on the rear hatch to gain access to the wiper motor.
  • Inspect connections: Look for any loose, corroded, or damaged wires. Clean or repair as necessary.
  • Reconnect the wiring harness: Ensure all connections are secure.
4. Test the Rear Wiper Motor
  • Direct power test: Disconnect the wiper motor from its wiring harness. Use jumper wires to connect the motor directly to the vehicle battery.
  • Listen for operation: If the motor operates, the issue may be in the switch or wiring. If it does not operate, the motor may need replacement.
5. Replace the Rear Wiper Motor (if necessary)
  • Remove the wiper arm: Use a flathead screwdriver to carefully pry off the wiper arm cap, then remove the arm using a socket.
  • Uninstall the motor: Remove the bolts securing the motor and carefully disconnect the wiring harness.
  • Install the new motor: Reverse the removal process to install the new motor, ensuring all bolts are torqued to specification.
  • Reattach the wiper arm: Place the wiper arm back on the motor shaft and secure it.
