Solution

1. Preparation

Gather tools: socket set, multimeter, flathead screwdriver, and replacement parts if necessary.
Ensure the vehicle is parked on a flat surface and the ignition is off.

2. Inspect and Replace the Wiper Fuse

Locate the fuse box, usually found under the dashboard or in the engine compartment.
Identify the wiper fuse using the diagram on the fuse box cover.
Remove the fuse using a fuse puller or pliers.
Inspect the fuse for continuity; replace it if it is blown with a new fuse of the same amperage.

3. Test the Wiper Motor

Disconnect the wiper motor connector.
Set the multimeter to measure DC voltage and connect the leads to the motor connector.
Turn the wiper switch to the ON position to check for voltage; if voltage is present, the motor may need replacing.
If no voltage is detected, trace wiring back to the fuse box and investigate further.

4. Inspect the Wiper Linkage

Remove the wiper arms using a flathead screwdriver to carefully pry off the caps and unbolt the arms.
Remove the cowl cover to access the wiper linkage.
Check for any loose or damaged joints; replace any faulty components.
Reassemble the linkage, ensuring it moves freely.

5. Replace Wiper Motor (if necessary)

If the motor is faulty, unbolt it from its mounting.
Disconnect the electrical connector and remove the motor from the vehicle.
Install the new motor by securing it in place and reconnecting the electrical connector.

Tools Required:
