Solution

1. Preparation

Tools Required:
- Multimeter
- Screwdrivers (flathead and Phillips)
- Socket set
- Torque wrench
- Pliers
Disconnect the vehicle battery to ensure safety while working on the electrical components.

2. Replace Wiper Fuse

Locate the fuse box under the dashboard or in the engine compartment.
Identify the wiper fuse using the fuse diagram.
Remove the fuse with pliers and inspect it for continuity. If blown, replace it with a new fuse of the same amperage.

3. Test and Replace Wiper Motor

Reconnect the battery and turn on the ignition.
Use a multimeter to test for voltage at the wiper motor connector with the wiper switch activated.
If no voltage is present, trace back to the wiring or relay. If voltage is present but the motor does not operate, proceed to replace the wiper motor.
To replace, remove the wiper arms by unscrewing the nuts, then detach the motor by unscrewing it from its mounting points and disconnecting the electrical connector.
Install the new wiper motor in reverse order of removal.

4. Inspect Wiper Linkage

If the wiper motor is functioning but wipers do not move, the linkage may be faulty.
Remove the wiper arms and motor as described above.
Inspect the linkage for any signs of wear, bending, or disconnection.
If damaged, replace the linkage assembly.

5. Reassemble Components

Reinstall the wiper motor and linkage, ensuring all screws are tightened to manufacturer specifications.
Reattach the wiper arms and secure them with nuts.
Reconnect the battery.
