Solution

1. Preparation

Gather tools and materials needed for the repair.
Disconnect the battery to ensure safety while working on the electrical system.

Tools Required:

Multimeter
Socket set
Screwdriver set
Pliers

2. Check and Replace the Fuse

Locate the fuse box, typically found under the dashboard or in the engine compartment.
Identify the wiper fuse (refer to the owner's manual for location).
Remove the fuse and inspect it for a blown element.
If blown, replace it with a fuse of the same amperage.

3. Inspect and Replace the Wiper Switch

Remove the steering column cover using a screwdriver.
Disconnect the electrical connector from the wiper switch.
Use a multimeter to test continuity across the switch terminals.
If faulty, replace the wiper switch with a new one and reconnect the electrical connector.

4. Test and Replace the Wiper Motor

Locate the wiper motor, usually found near the base of the windshield.
Disconnect the electrical connector from the wiper motor.
Use a multimeter to test for voltage at the connector when the wiper switch is activated.
If there is voltage but the motor does not run, replace the wiper motor.
If there is no voltage, check the wiring harness for damage.

5. Reassemble and Test

Reinstall any covers or components removed during the process.
Reconnect the battery and test the windshield wipers for proper operation.
