Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the negative terminal of the battery to avoid electrical shorts.
Ensure the vehicle is parked on a level surface.

2. Inspect and Replace the Fuse

Tools Required: Fuse puller or needle-nose pliers
Locate the fuse box in the cabin or engine compartment.
Identify the fuse for the rear wiper (refer to the owner's manual for the correct location).
Remove the fuse and inspect it; if the metal wire inside is broken, replace it with a new fuse of the same amperage.

3. Test and Replace the Wiper Motor

Tools Required: Multimeter, screwdriver, socket set
Reconnect the battery terminal.
Use a multimeter to check for voltage at the wiper motor connector while the wiper switch is on.
If voltage is present but the motor does not operate, remove the motor by unscrewing its mounting bolts and disconnecting the wiring harness.
Install the new wiper motor by reversing the removal process. Ensure it is properly secured and connected.

4. Inspect and Repair the Wiper Linkage

Tools Required: Socket set, lubricant
Remove the rear wiper arm by loosening the nut at the base with a socket set.
Detach the plastic cover over the wiper linkage to access the mechanism.
Inspect the linkage for any disconnections or wear. If the linkage is damaged, replace it.
Lubricate any moving parts to ensure smooth operation before reassembling.

5. Reassemble Components

Reattach the wiper arm securely to the motor.
Replace any panels or covers removed during the repair.
Reconnect the negative battery terminal.
