Solution

1. Preparation

Gather tools including a multimeter, socket set, and screwdrivers.
Ensure the vehicle is parked on a level surface and the ignition is off.
Disconnect the vehicle battery to prevent electrical shock.

2. Replace Blown Fuse

Locate the fuse box; it is usually found under the dashboard on the driver's side or in the engine compartment.
Remove the cover and locate the wiper fuse (refer to the diagram on the fuse box cover).
If the fuse is blown, replace it with a new fuse of the same amperage.

3. Repair or Replace Wiper Switch

Remove the steering column cover using a screwdriver.
Disconnect the wiring harness from the wiper switch.
Test the switch with a multimeter to check for continuity.
If faulty, replace the wiper switch with a new one and reconnect the wiring harness.

4. Test and Replace Wiper Motor (if necessary)

Locate the wiper motor (usually under the cowl panel).
Disconnect the wiring harness from the wiper motor.
Use a multimeter to test for voltage at the connector when the wiper switch is activated.
If no voltage is present, the issue may be with the wiring; repair as needed.
If voltage is present and the motor does not operate, replace the wiper motor.
- Remove the mounting bolts and disconnect the wiper linkage.
- Install the new motor, reattach the linkage, and secure it with bolts.

5. Reassemble and Test

Reassemble any panels or covers that were removed.
Reconnect the vehicle battery.
Test the wipers by activating the switch in different settings.
