Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the vehicle's battery to ensure safety while working on electrical components.
Tools Required: Socket set, multimeter, flathead screwdriver, and wrenches.

2. Check and Replace Fuse

Locate the fuse box under the dashboard or in the engine compartment.
Identify the rear wiper fuse using the fuse diagram.
Remove the fuse and inspect it; replace it with a new fuse of the same amperage if it is blown.

3. Inspect Wiring and Connectors

Remove the rear wiper arm by loosening the retaining nut with a socket wrench.
Carefully pull off the wiper arm from the shaft.
Inspect the wiring harness leading to the rear wiper motor for frays, corrosion, or disconnections.
Clean any corroded connectors using electrical contact cleaner and reconnect.

4. Test and Replace Wiper Motor (if necessary)

Connect the battery back and use a multimeter to check for voltage at the wiper motor connector when the switch is activated.
If voltage is present but the motor does not operate, replace the rear wiper motor.
To replace the motor, remove the screws or bolts securing it, disconnect the wiring harness, and install the new motor in reverse order.

5. Reassembly

Reattach the rear wiper arm and tighten the retaining nut to the manufacturer's specified torque (typically around 10-15 ft-lbs).
Reconnect the battery and test the rear wiper for proper operation.
