Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the battery to ensure safety while working on electrical components.

2. Check and Replace Wiper Fuse

Locate the fuse box and identify the wiper fuse (refer to the owner’s manual for specific location).
Remove the fuse and inspect it; if blown, replace it with a new fuse of the same amperage.
Reconnect the battery and test the wipers.

3. Inspect and Replace Wiper Relay

Locate the wiper relay in the fuse box or under the dashboard.
Remove the relay and test it using a multimeter for continuity.
If faulty, replace with a new relay of the same specifications.

4. Test and Replace Wiper Motor

Locate the wiper motor (usually under the cowl panel).
Disconnect the electrical connector and test for voltage at the motor terminals while activating the wipers.
If there is no voltage, trace back to the switch and wiring. If voltage is present and the motor does not operate, replace the wiper motor.

5. Inspect Wiper Linkage

Remove the wiper arms using a puller tool if necessary.
Inspect the linkage for any signs of wear or disconnection.
If damaged, replace the wiper linkage assembly.

6. Check Washer System

Inspect the washer fluid reservoir for fluid level.
Check hoses for blockages or leaks.
If the washer pump is not working, test it and replace if necessary.
