Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface and the ignition is off.
Disconnect the negative terminal of the battery for safety.

2. Inspect and Replace Fuse

Locate the fuse box in the vehicle (refer to the owner's manual for exact location).
Use a fuse puller to remove the wiper fuse.
Inspect the fuse for continuity; replace it with a new one of the same amperage if blown.

3. Check and Replace Wiper Control Stalk

Remove the steering column cover using a socket set.
Disconnect the wiring harness connected to the wiper control stalk.
Replace the control stalk if it shows any signs of damage or malfunction.

4. Test and Replace Wiper Motor

Reconnect the vehicle battery temporarily.
Using a multimeter, check the voltage at the wiper motor connector when the wiper switch is activated.
If no voltage is present, further diagnose the wiring; if voltage is present but the motor does not operate, replace the wiper motor.

5. Inspect and Repair Wiper Linkage

Remove the wiper arms by loosening the retaining nuts with a socket set.
Detach the wiper linkage from the motor and inspect it for damage or wear.
Replace any damaged linkage components and reassemble.

6. Reassemble Components

Reinstall the wiper arms and secure them with nuts.
Reconnect the battery terminal.
Ensure all covers and panels are reattached properly.
