Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Disconnect the 12V battery to ensure safety during the repair.

2. Inspect and Replace the Fuse

Locate the fuse box under the dashboard or in the front trunk.
Remove the cover and find the wiper fuse (consult the owner’s manual for the exact location).
Use a fuse puller to extract the fuse and inspect it for continuity.
- If blown, replace it with a new fuse of the same amperage (typically 10A or 15A).

3. Check the Wiper Motor

Reconnect the battery and turn on the ignition.
Access the wiper motor, usually located under the cowl panel at the base of the windshield.
Inspect the wiring harness for any damage or loose connections.
Use a multimeter to test for voltage at the motor connector while operating the wiper switch.
- If no voltage is detected, further investigate the wiring or switch.

4. Inspect and Repair the Wiper Linkage

Remove the wiper arms using a puller tool if necessary.
Disconnect the wiper motor from the linkage.
Examine the linkage for wear, corrosion, or binding.
- If damaged, replace the wiper linkage assembly.
- Lubricate moving parts as needed with suitable grease.

5. Test the Wiper Fluid Pump

Locate the wiper fluid reservoir and ensure it has fluid.
Disconnect the pump's electrical connector and test for voltage while activating the wiper fluid switch.
- If no voltage, check the wiring and switches.
- If voltage is present but the pump doesn’t operate, replace the wiper fluid pump.
