how to fix the rear window wiper on my Volkswagen Tiguan First Generation (2007-2018)

Solution

1. Preparation

• Gather tools: Phillips screwdriver, flathead screwdriver, multimeter, wire stripper, and electrical tape.
• Ensure the vehicle is parked on a level surface, and the ignition is off.

2. Remove the Rear Wiper Arm

• Use a flathead screwdriver to gently pry off the plastic cover at the base of the wiper arm.
• Remove the nut securing the wiper arm using a socket set (typically a 13mm socket).
• Gently rock and pull the wiper arm off the motor shaft.

3. Inspect and Test the Wiper Motor

• Disconnect the wiring harness from the wiper motor.
• Use a multimeter to check for voltage at the motor's connector while operating the wiper switch.
  • If there is voltage, the motor may be faulty.
  • If no voltage, trace the wiring back to the switch.
• If testing confirms the motor is faulty, proceed to replace it.

4. Replace the Wiper Motor (if needed)

• Remove any retaining screws holding the motor in place and take out the old motor.
• Install the new wiper motor in reverse order and secure it with retaining screws.
• Reconnect the wiring harness.

5. Reassemble the Wiper Arm

• Position the wiper arm back onto the motor shaft.
• Secure it with the nut using a socket set, ensuring it is tight but not over-torqued.
• Replace the plastic cover over the wiper arm base.

6. Test the Repair

• Turn on the ignition and activate the rear wiper to confirm proper operation.
