Solution

1. Preparation

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

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 fuse box diagram (refer to the owner’s manual).
Remove the fuse using a fuse puller or pliers.
Inspect the fuse; if it is blown, replace it with a new fuse of the same amperage.

3. Test the Wiper Switch

Reconnect the battery.
Use a multimeter to test the wiper switch for continuity.
If the switch is faulty, remove the steering column cover and disconnect the switch connector.
Replace the wiper switch with a new one.

4. Inspect and Test the Wiper Motor

If the fuse and switch are functioning, locate the wiper motor, typically mounted under the cowl.
Disconnect the electrical connector from the wiper motor.
Using a multimeter, check for voltage at the connector when the wiper switch is activated.
If there is voltage but the motor does not operate, replace the wiper motor.

5. Reassemble and Test

Reattach any panels or covers removed during the inspection.
Reconnect the battery.
Test the wipers to ensure they operate correctly.
