Solution

1. Preparation

Tools Required: Socket set, multimeter, screwdriver, replacement fuse (if necessary), replacement wiper motor (if necessary).
Safety Warnings: Disconnect the battery before working on electrical components to prevent short circuits.

2. Check and Replace Fuse

Locate the fuse box (usually under the dashboard or in the engine compartment).
Identify the rear wiper fuse using the diagram on the fuse box cover.
Remove the fuse using a fuse puller or pliers, and visually inspect it for any breaks in the filament.
Replace with a fuse of the same amperage if it is blown.

3. Test and Replace Wiper Motor

Remove the rear wiper arm by unscrewing the mounting nut and gently pulling the arm off.
Disconnect the wiring harness from the rear wiper motor.
Using a multimeter, check for power at the wiper motor connector while activating the rear wiper switch.
If no power is present, trace the wiring for faults.
If power is present and the motor does not work, remove the motor from its mounting bracket (typically requires unscrewing).
Install the new wiper motor by reversing the removal steps and reconnect the wiring harness.

4. Reassemble Components

Reattach the rear wiper arm securely onto the motor shaft.
Ensure all screws and bolts are tightened to manufacturer specifications (typically around 10-15 ft-lbs for the wiper arm nut).
Reconnect the vehicle battery.
