Solution

1. Preparation

Gather tools and safety equipment.
Disconnect the negative terminal of the battery to prevent electrical shock.

2. Inspect and Replace Wiper Control Stalk

Tools Required: Screwdriver set, trim removal tool.
Remove the steering column cover by unscrewing the relevant screws.
Carefully detach the wiper control stalk connector and inspect for corrosion or damage.
If damaged, replace with a new wiper control stalk by reversing the removal steps.

3. Check and Replace Fuses

Tools Required: Fuse puller or needle-nose pliers.
Locate the fuse box; refer to the owner's manual for the wiper fuse location.
Remove the wiper fuse and inspect it for continuity.
If blown, replace it with a fuse of the same amperage.

4. Inspect and Replace Wiper Relay

Tools Required: Relay testing tool (optional).
Identify the wiper relay in the fuse box.
Test the relay for continuity; if defective, replace it with a new relay.
Reinstall the relay securely.

5. Test Wiper Motor Functionality

Tools Required: Multimeter, wiring harness connector.
Reconnect the wiper motor connector.
Use a multimeter to check for voltage at the motor terminals while the wiper switch is activated.
If no voltage is detected, further investigate the wiring or the switch.
