Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the negative battery terminal to prevent electrical shock.
Ensure the vehicle is parked on a level surface with the ignition off.

2. Inspect and Replace the Wiper Switch

Tools Required: Screwdrivers, multimeter
Remove the wiper switch from the steering column by unscrewing and disconnecting the wiring harness.
Test the switch with a multimeter for continuity in each position.
If defective, replace with a new wiper switch and reconnect the wiring harness.

3. Check and Replace the Wiper Fuse

Tools Required: Fuse puller or pliers
Locate the fuse box (refer to the owner's manual for the exact location).
Remove the wiper fuse and inspect it for damage; replace if blown (usually a 20A fuse).
Reinsert the new fuse and ensure it is secure.

4. Test the Wiper Motor

Tools Required: Multimeter, socket set
Reconnect the battery terminal.
Access the wiper motor, typically located under the cowl panel.
Use the multimeter to check for voltage at the motor connector while activating the wiper switch.
If voltage is present but the motor does not operate, replace the wiper motor.

5. Inspect and Repair the Wiper Linkage

Tools Required: Socket set, pliers
Remove the wiper arms by loosening the retaining nut and gently pulling them off.
Inspect the wiper linkage for wear or disconnection from the motor.
If damaged, replace the wiper linkage assembly.
