1. Preparation

Gather necessary tools and parts.
Disconnect the vehicle battery to ensure safety while working on electrical components.

2. Inspect and Replace Fuse

Tools Required: Fuse puller or pliers
Locate the fuse box and find the rear wiper fuse.
Remove the fuse and inspect for continuity using a multimeter.
If blown, replace with a fuse of the same amperage.

3. Test and Replace Rear Wiper Motor

Tools Required: Socket set, multimeter
Disconnect the wiring harness from the rear wiper motor.
Use a multimeter to check for voltage at the motor connector when the wiper is activated.
If voltage is present but the motor does not operate, remove the motor by unscrewing it from the mounting bracket.
Install a new rear wiper motor by reversing the removal steps and reconnecting the wiring harness.

4. Check and Secure Wiper Arm

Tools Required: Wrench set
Inspect the wiper arm for tightness. If loose, tighten the nut securing the arm to the motor shaft.
If the wiper arm is damaged, replace it with a new one.

5. Address Washer Functionality

If the washer function is inoperative, remove the rear cover panel and inspect the hose for kinks or disconnections.
Clear any blockage in the nozzle with a pin or replace the nozzle if necessary.
