Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the negative terminal of the battery to ensure safety.

2. Inspect and Replace the Fuse

Locate the fuse box (refer to the owner’s manual for the exact location).
Remove the wiper fuse using a fuse puller.
Inspect the fuse for continuity; replace if blown with a new fuse of the same amperage.

3. Test the Wiper Switch

Remove the steering column cover using a screwdriver.
Disconnect the wiper switch connector.
Use a multimeter to test for continuity across the switch terminals when toggled.

4. Check the Wiper Motor

Locate the wiper motor, usually found under the cowl panel.
Disconnect the wiring harness from the motor.
Apply 12V directly to the motor terminals using jumper wires to see if it operates.
If it does not operate, replace the wiper motor.

5. Inspect Wiring and Connections

Visually inspect the wiring harness for any signs of wear, fraying, or corrosion.
Repair any damaged wires using solder and heat shrink tubing.

6. Reassemble and Test

Reconnect all connectors and covers.
Reconnect the negative terminal of the battery.
Test the wipers to ensure they function correctly.
