Solution

1. Preparation

Gather tools: socket set, multimeter, flat-head screwdriver, and replacement parts if necessary.
Disconnect the negative terminal of the battery to ensure safety while working on electrical components.

2. Check and Replace Fuse

Locate the fuse box, typically found under the dashboard or in the engine compartment.
Identify the fuse for the rear wiper (refer to the owner's manual for the exact location).
Remove the fuse and inspect it for continuity. Replace if blown with the same amperage rating.

3. Inspect and Replace Wiper Motor

Remove the rear wiper arm by loosening the retaining nut with a socket wrench.
Gently pull the wiper arm off the shaft.
Unscrew the mounting bolts that secure the wiper motor to the vehicle.
Disconnect the wiring harness from the motor.
Install the new wiper motor by reversing the disassembly steps, ensuring all connections are secure.

4. Check Wiring and Connectors

Inspect the wiring harness for any frays or damage. Repair or replace as necessary.
Ensure all connectors are clean and securely fastened. Use electrical contact cleaner if corroded.

5. Verify Washer Fluid Operation

If the washer fluid is not dispensing, check the fluid level in the reservoir.
Test the washer pump by applying 12V directly to it to see if it functions. Replace if defective.
Ensure the washer nozzle is clear of debris.
