Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the negative terminal of the battery to ensure safety during electrical repairs.
Tools required: Socket set, multimeter, wiring harness repair kit (if needed).

2. Check and Replace Fuse

Locate the fuse box, typically found on the dashboard or under the hood.
Identify the fuse for the rear wiper using the fuse diagram located inside the fuse box cover.
Remove the fuse using a fuse puller or pliers and inspect for damage.
If blown, replace it with a fuse of the same amperage (check the owner's manual for specifications).

3. Inspect the Rear Wiper Motor

Access the rear wiper motor by removing the interior panel on the tailgate if necessary.
Disconnect the wiring harness from the motor.
Use a multimeter to check for voltage at the connector while engaging the wiper switch; if voltage is present, the motor is likely faulty.
If testing confirms a faulty motor, remove the motor by unscrewing the mounting bolts and disconnecting it from the wiper arm.
Install a new rear wiper motor in reverse order of removal and reconnect the wiring harness.

4. Check Wiring and Connections

Inspect the wiring leading to the rear wiper motor for any signs of wear, fraying, or disconnection.
Repair any damaged wires using a wiring harness repair kit.
Ensure all connectors are clean and securely attached.

5. Test the Rear Washer Pump

If the rear washer is not functioning, inspect the washer fluid reservoir for adequate fluid levels.
Remove the rear washer pump from the reservoir and test it by applying power directly from a battery to see if it operates.
Replace the washer pump if it does not work.
