Solution

1. Preparation

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

2. Inspect and Replace the Fuse

Locate the fuse box, usually found under the dashboard or in the engine compartment.
Remove the cover and identify the wiper fuse using the diagram.
Check the fuse; if blown, replace it with one of the same amperage.

3. Test and Replace the Wiper Switch

Remove the steering column cover to access the wiper switch.
Unplug the switch connector and use a multimeter to check for continuity when the switch is activated.
If faulty, replace the wiper switch with a new one.

4. Check and Replace the Wiper Motor

Remove the wiper arms by loosening the nuts at their bases, then gently lifting them off.
Unscrew the wiper motor from its mounting position.
Disconnect the wiring harness from the motor and inspect for damage.
Install a new wiper motor if the old one is defective, securing it in place and reconnecting the harness.

5. Inspect Wiring and Relays

Follow the wiring harness from the wiper motor to the fuse box, checking for any visible damage or disconnections.
If the wiring appears intact but issues persist, locate the wiper relay in the fuse box and test it.
Replace the relay if it fails to operate correctly.
